Supertwist liquid crystal display
The invention relates to supertwist liquid
crystal displays (SLD) having very short switching times
and good steepness and angle dependence, and also to the
novel nematic liquid crystal mixtures used therein.
SLD according to the preamble are known, for
example from EP 0,131,216 B1; DE 3,423,993 A1; EP
0,098,070 A2; M. Schadt and F. Leenhouts, 17th Freiburger

Raynes, Mol. Cryst. Liq. Cryst. Letters volume 4 (1),
pages 1-8 (1986). The term SLD here comprises any more
highly twisted display element with an amount of twist
angle between 100 and 600, such as, for example, the
display elements according to Waters et al. (C. M. Waters
( et al., Proc. Soc. Inf. Disp. (New York) (1985) (3rd
Intern. Display Conference, Robe, Japan), the STN-LCD

Application 0,246,842) or BW-STN-LCD (R. Kawasaki et al.,
SID 87 Digest 391 (20.6)).
' Compared with standard twisted nematic displays,
SLD of this type are distinguished by substantially
better steepness of the electro-optical characteristic
and thus associated better contrast values and by a
substantially smaller angle dependence of the contrast.
SLD with very short switching times are here of par-

ticular interest, especially also at relatively low
temperatures. To achieve short switching times, the
viscosities of the liquid crystal mixtures have hitherto
been optimized with the use of, in most cases, monotropic
additives having a relatively high vapour pressure.
However, the switching times achieved were not adequate
for some applications.
To achieve a steep electro-optical characteris
tic, the liquid crystal mixtures should have relatively
high wide (sic) values for K3/K1 and relatively small
values for oE/E1.
Beyond the optimization of the contrast and
switching times, mixtures of this type have to meet
further important demands:
1. a wide d/p window
2. a high chemical fatigue stability
3. a high electrical resistance
4. a low frequency dependence of the threshold voltage.
The parameter combinations achieved are not yet
nearly sufficient, in particular for high-multiplex STN
(1/400). In part, this is to be ascribed to the fact that
the various demands are affected in opposite directions
by material parameters.
There is thus still a great demand for SLD which
have very short switching times coupled with, at the same
n time, a wide range of working temperatures, high steep
ness of the characteristic, good angle dependence of the
contrast and low threshold voltage and which meet the
demands given above.
The invention is based on the object of providing
SLD which show the above-indicated disadvantages only to
a smaller extent or not at all and, at the same time,
have very short switching times.
It has now been found that this object can be
achieved if the nematic liquid crystal mixture
a) is based on component A containing one or more
compounds seleted from group A comprising compounds
of the formulae IIa to IIk~c

threshold voltage vlo~ciao and of the flow viscosity r~ and are
diatinguis_rled by fairly high or high values of the optical
anisotropy. These mixtures are preferred.
For component D, a large number of chiral doping
substances, some of which are commercially obtainable, are
a~Tailable to those skilled in the art. The choice of these is
not critical per se.
The liquid crystal mixtures used in the SLD according
to the inven~l.ion are dielectrically positive with ~F z 1.
Liquid cry9tal mixtures with Ds _> 3 are particularly preferred,
and very particularly those with a~ ? 5.

invention have advantageous values of the threshold

voltage Vloioiao and of the flow viscosity n. If the value
of the optical path difference den is given, the value
.of the layer thickness d is determined by the optical
anisotropy en. Using i.a. liquid crystal mixtures accord-
s ing to the invention with a relatively high or high value
of the optical anisotropy is preferred, especially in the
case of relatively high or high values of don, since the
value of d can then be selected to be relatively small,
which brings about more advantageous values of the
switching times. However, those liquid crystal displays
according to the invention which contain liquid crystal
mixtures according to the invention having smaller values
of en are also characterized by advantageous values of
the switching times. The liquid crystal mixtures accord-
ing to the invention are characterized further by advan-
tageous values of the steepness of the electro-optical
characteristic and can be operated at high multiplex
rates. Moreover, the liquid crystal mixtures according to
the invention have high stability and advantageous values
of electrical resistance and of frequency dependence of
the threshold voltage. The liquid crystal displays
according to the invention have a wide range of working
temperatures and good angle dependence of the contrast.
The structure of the liquid crystal display
elements according to the invention from polarizers,
,' electrode base plates and electrodes with such a surface
treatment that the preferential orientation (director) of
the adjoining liquid crystal molecules from one electrode
to the other is in each case twisted usually by an amount
of 160 to 360 relative to one another, corresponds to
the type of construction which is conventional for such
display elements . The term co~entional type of construc-
tion is here used in a wide meaning and also comprises
all variations and modifications of the supertwist cell,
and in particular also matrix display elements and the
display elements containing additional magnets according
to German Offenlegungsschrift 2,748,738. The surface tilt
angles at the two carrier plates can be equal or dif-
ferent. Equal tilt angles are preferred.

However, an essential difference between the
display elements according to the invention and the
.hitherto conventional ones on the basis of the twisted
nematic cell resides in the choice of the liquid crystal
components of the liquid crystal layer.
The liquid crystal mixtures which can be used
according to the invention are prepared in a manner
conventional per se.
As a rule, the desired quantity of the components
used in a smaller amount is dissolved in the components
representing the main constituent, advantageously at an
elevated temperature. It is also possible to mix
solutions of the components in an organic solvent, for
example in acetone, chloroform or methanol, and, after
thorough mixing, to remove the solvent again, for example
- by distillation.
The dielectrics can also contain further addi
tives known to those skilled in the art and described in
the literature. For example, 0-15% of pleochroic dyes can
be added.
The examples which follow are intended to explain
the invention, without limiting it.
In the examples:
S-N is the smectic/nematic phase transition
temperature,
c.p. is the clearing point,
visc. is the viscosity (mPa.s),
Ton is the time from switching on until 90% of the
maximum contrast is reached, and
Tuff is the time from switching off until 10% of the
maximum contrast is reached.
The SLD is activated in multiplex operation
(multiplexing ratio 1:100, bias 1:11, operating voltage
18.5 volt).
Above and below, all temperatures are given in
°C. The percentage figures are percent by weight. The
values of the switching times and viscosities refer to
