Description

The invention relates to supertwist liquid crystal displays (SLCD) having very short switching times and good gradients and angular dependencies and the new nematic liquid crystal mixtures used in these.

SLCD according to the precharacterizing clause are known, for example, from EP 0,131,216 B1; DE 34 23 993 A1; EP 0,098,070 A2; M. Schadt and F. Leenhouts, 17.

A. van Sprang and H. G. Koopman, J. Appl. Phys. 62 (5), 1734 (1987); T. J. Scheffer and J. Nehring, Appl. Phys. Lett. 45 (10), 1021 (1984), M. Schadt and F. Leenhouts, Appl. Phys. Lett. 50 (5), 236 (1987) and E. P. Raynes, Mol. Cryst. Liq. Cryst. Letters Volume 4 (1), pages 1-8 (1986). The term SLCD here includes any highly twisted display element having a twisting angle, according to the content, of between 160.degree. and 360.degree., 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, Kobe, Japan), and the STN-LCDs (DE OS 35 03 259), SBE-LCDs (T. J. Scheffer and J. Nehring, Appl. Phys. Lett. 45 (1984) 1021), OMI-LCDs (M. Schadt and F. Leenhouts, Appl. Phys. Lett. 50 (1987), 236), DST-LCDs (EP OS 0 246 842) or BW-STN-LCDs (K. Kawasaki et al., SID 87 Digest 391 (20.6)).

In contrast to standard TN displays, such SLCD are distinguished by considerably better gradients of the electrooptical characteristic line and associated better contrast values, as well as by a considerably lower angular dependency of contrast. SLCD having short switching times, especially also at lower temperatures, are of particular interest. To achieve short switching times, the viscosities of the liquid crystal mixtures in particular have hitherto been optimized using usually monotropic additives of relatively high vapor pressure. However, the switching times achieved were not adequate for every use.

There is thus still a great demand for SLCD having very short switching times with a simultaneously high working temperature range, high characteristic line gradient, good angular dependency of the contrast and low threshold voltage.

The invention is based on the object of providing SLCD which have the abovementioned disadvantages to only a minor degree, if at all, and at the same time have very short switching times.

It has now been found that this object can be achieved if nematic liquid crystal mixtures containing the following components:

a) at least one component chosen from group A, consisting of compounds of the formulae AI to AVI: ##STR2## wherein R.sup.1 and R.sup.2 each independently of one another are each R and R is alkyl having 1-12 C atoms, wherein one or two non-adjacent CH.sub.2 groups can also be replaced by --O--, --CH.dbd.CH--, --CO--, --O--CO-- or --CO--O--, b) at least one component chosen from group B1, consisting of the compounds of the formulae BI to BIV: ##STR3## wherein R.sup.1 and R.sup.2 each independently of one another have the meaning given for R, Z.sup.2 is --CH.sub.2 CH.sub.2 --, --CO--O--, --O--CO-- or a single bond and ##STR4## and/or at least one component chosen from group B2, consisting of the compounds of the formulae BV to BVII: ##STR5## wherein R.sup.1 has the meaning given for R, Z.sup.9 is --CH.sub.2 CH.sub.2 -- or a single bond and Q is ##STR6## wherein n is 1 to 9, X is CN or F and Y is H or F, and/or at least one component chosen from group B3, consisting of the compounds of the formulae BVIII and BIX: ##STR7## wherein R.sup.1 and R.sup.2 each independently of one another have the meaning given for R and ##STR8## c) 10-80% by weight of a liquid crystal component C, consisting of one or more compounds having a dielectric anisotropy of more than +1.5, d) 0-20% by weight of a liquid crystal component D, consisting of one or more compounds having a dielectric anisotropy of less than -1.5 and e) an optically active component E, in an amount such that the ratio between the layer thickness (separation of the plane-parallel carrier plates) and the natural pitch of the nematic liquid crystal mixture is about 0.2 to 1.3, are used.

The invention thus relates to an SLCD having

two plane-parallel carrier plates which, with an edging, form a cell, a nematic liquid crystal mixture of positive dielectric anisotropy in the cell, electrode layers with superimposed orientation layers on the insides of the carrier plates, an angle of incidence between the longitudinal axis of the molecules on the surface of the carrier plates and the carrier plates of about 1 degree to 30 degrees and a twisting angle of the liquid crystal mixture in the cell from orientation layer to orientation layer, according to the amount, of between 160.degree. and 360.degree., characterized in that the nematic liquid crystal mixture contains a) at least one component chosen from group A, consisting of compounds of the formulae AI to AVI: ##STR9## wherein R.sup.1 and R.sup.2 each independently of one another are each R and R is alkyl having 1-12 C atoms, wherein one or two non-adjacent CH.sub.2 groups can also be replaced by --O--, --CH.dbd.CH--, --CO--, --O--CO-- or --CO--O--, b) at least one component chosen from group B1, consisting of the compounds of the formulae BI to BIV: ##STR10## wherein R.sup.1 and R.sup.2 each independently of one another have the meaning given for R, Z.sup.2 is --CH.sub.2 CH.sub.2 --, --CO--O--, --O--CO-- or a single bond and ##STR11## and/or at least one component chosen from group B2, consisting of the compounds of the formulae BV to BVII: ##STR12## wherein R.sup.1 has the meaning given for R, Z.sup.0 is --CH.sub.2 CH.sub.2 -- or a single bond and Q is ##STR13## wherein n is 1 to 9, X is CN or F and Y is H or F, and/or at least one component chosen from group B3, consisting of the compounds of the formulae BVIII and BIX: ##STR14## wherein R.sup.1 and R.sup.2 each independently of one another have the meaning given for R and ##STR15## c) 10-80% by weight of a liquid crystal component C, consisting of one or more compounds having a dielectric anisotropy of more than +1.5, d) 0-20% by weight of a liquid crystal component D, consisting of one or more compounds having a dielectric anisotropy of less than -1.5 and e) an optically active component E, in an amount such that the ratio between the layer thickness (separation of the plane-parallel carrier plates) and the natural pitch of the nematic liquid crystal mixture is about 0.2 to 1.3, and in that the nematic liquid crystal mixture has a nematic phase range of at least 60.degree.

The expert can easily adjust this content to establish the desired threshold voltage, it being possible on principle to use all the customary liquid crystal compounds of .DELTA..epsilon.>+1.5. If predominantly less highly positive terminally fluorinated compounds (see above) are used, the total content varies more in the above range (about 35% to 80%), whereas if terminally cyano-substituted compounds are used, the content can be lower (about 10% to 35%).

Such compounds are known, for example derivatives of 2,3-dicyanohydroquinone or cyclohexane derivatives containing the structural element ##STR30## in accordance with DE-OS 32 31 707 and DE-OS 34 07 013.

Preferably, however, compounds having the structural element 2,3-difluoro-1,4-phenylene will be chosen, for example compounds according to DE-OS 38 07 801, 38 07 861, 38 07 863, 38 07 864 or 38 07 908. Tolanes having this structural element according to International Patent Application PCE/DE 88/00133 are particularly preferred, especially those of the formulae ##STR31## wherein R.sup.1 and R.sup.2 each independently of one another are preferably n-alkyl having 1 to 7 C atoms or n-alkenyl having 3 to 7 C atoms and Z.sup.0 is --CH.sub.2 --CH.sub.2 -- or a single bond.

The component D has the effect, in particular, of improving the gradient of the characteristic line.

In a particularly preferred embodiment, the mixtures contain about 5% to 35%, particularly preferably about 10% to 20%, of liquid crystal tolane compounds.

The expert has available a large number of chiral doping substances, some of which are commercially available, for component E. Their choice is not critical per se.

The build-up of the liquid crystal display elements according to the invention of polarizers, electrode baseplates and electrodes having a surface treatment such that the preferred orientation (director) of the liquid crystal molecules in each case adjacent thereto is usually twisted from the one electrode to the other by, according to the amount, 160.degree. to 360.degree. relative to one another, corresponds to the usual construction for such display elements. The term usual construction here is interpreted widely and also includes all the variations and modifications of the supertwist cell which are known from the literature, in particular also matrix display elements, as well as the display elements, containing additional magnets, according to DE-OS 2 748 738. The surface tilt angle of the two carrier plates can be identical or different. Identical tilt angles are preferred.

However, an essential difference between the display elements according to the invention and those which were hitherto customary and are based on the twisted nematic cell is in the choice of liquid crystal components in the liquid crystal layer.

The liquid crystal mixtures which can be used according to the invention are prepared in a manner which is customary per se. As a rule, the desired amount of the components used in the smaller amount is dissolved in the components which make up the main constituent, preferably at elevated temperature. It is also possible to mix solutions of the components in an organic solvent, for example in acetone, chloroform or methanol, and to remove the solvent again, for example by distillation, after thorough mixing.

The dielectrics can also contain other additives which are known to the expert and are described in the literature. For example 0-15% of pleochroic dyestuffs can be added.

The liquid crystal mixtures according to the invention can certainly additionally contain, apart from the components mentioned here, further customary components. One skilled in the art can determine by routine tests which other components can be employed and in which amounts without eliminating the advantages of the invention. Preferably, the mixtures predominantly comprise the components mentioned (more than 60% of them) and in particular almost exclusively these components (more than 80%, particularly preferably 100% of them).

The following examples are intended to illustrate the invention without limiting it.

The examples have the following meanings:

S-N smectic-nematic phase transition temperature, cp. clearing point, visc. viscosity (mPa.s), T.sub.on time from switching on to reaching 90% of the maximum contrast T.sub.off time from switching off to reaching 10% of the maximum contrast

The SLCD is driven in multiplex operation (multiplex ratio 1:100, bias 1:11, operating voltage 18.5 volts).

All the temperatures above and below are given in .degree.C. The percentage figures are percentages by weight. The values for the switching times and viscosities are based on 20.degree. C.
