Definitions

  • the invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I,
  • Media of this type can be used, in particular, for electro-optical displays having active-matrix addressing based on the ECB effect and for IPS (in-plane switching) displays or FFS (fringe field switching) displays.
  • IPS in-plane switching
  • FFS far field switching
  • VAN vertical aligned nematic displays
  • MVA multi-domain vertical alignment
  • MVA multi-domain vertical alignment
  • PVA patterned vertical alignment, for example: Kim, Sang Soo, paper 15.4: “Super PVA Sets New State-of-the-Art for LCD-TV”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 760 to 763)
  • ASV advanced super view, for example: Shigeta, Mitzuhiro and Fukuoka, Hirofumi, paper 15.2: “Development of High Quality LCDTV”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp.
  • LC phases which have to satisfy a multiplicity of requirements.
  • Particularly important here are chemical resistance to moisture, air and physical influences, such as heat, infrared, visible and ultraviolet radiation and direct and alternating electric fields.
  • LC phases are required to have a liquid-crystalline mesophase in a suitable temperature range and low viscosity.
  • None of the hitherto-disclosed series of compounds having a liquid-crystalline mesophase includes a single compound which meets all these requirements. Mixtures of two to 25, preferably three to 18, compounds are therefore generally prepared in order to obtain substances which can be used as LC phases. However, it has not been possible to prepare optimum phases easily in this way since no liquid-crystal materials having significantly negative dielectric anisotropy and adequate long-term stability were hitherto available.
  • Matrix liquid-crystal displays are known.
  • Non-linear elements which can be used for individual switching of the individual pixels are, for example, active elements (i.e. transistors).
  • active matrix is then used, where a distinction can be made between two types:
  • the electro-optical effect used is usually dynamic scattering or the guest-host effect.
  • the use of single-crystal silicon as substrate material restricts the display size, since even modular assembly of various part-displays results in problems at the joints.
  • the electrooptical effect used is usually the TN effect.
  • TFTs comprising compound semiconductors, such as, for example, CdSe, or TFTs based on polycrystalline or amorphous silicon.
  • CdSe compound semiconductors
  • TFTs based on polycrystalline or amorphous silicon The latter technology is being worked on intensively worldwide.
  • the TFT matrix is applied to the inside of one glass plate of the display, while the other glass plate carries the transparent counterelectrode on its inside. Compared with the size of the pixel electrode, the TFT is very small and has virtually no adverse effect on the image.
  • This technology can also be extended to fully colour-capable displays, in which a mosaic of red, green and blue filters is arranged in such a way that a filter element is opposite each switchable pixel.
  • MLC displays of this type are particularly suitable for TV applications (for example pocket TVs) or for high-information displays in automobile or air-craft construction.
  • TV applications for example pocket TVs
  • high-information displays in automobile or air-craft construction Besides problems regarding the angle dependence of the contrast and the response times, difficulties also arise in MLC displays due to insufficiently high specific resistance of the liquid-crystal mixtures [TOGASHI, S., SEKIGUCHI, K., TANABE, H., YAMAMOTO, E., SORIMACHI, K., TAJIMA, E., WATANABE, H., SHIMIZU, H., Proc. Eurodisplay 84, September 1984: A 210-288 Matrix LCD Controlled by Double Stage Diode Rings, pp. 141 ff., Paris; STROMER, M., Proc.
  • the disadvantage of the MLC-TN displays frequently used is due to their comparatively low contrast, the relatively high viewing-angle dependence and the difficulty of generating grey shades in these displays.
  • the invention is based on the object of providing liquid-crystal mixtures, in particular for monitor and TV applications, based on the ECB, UB-FFS, IPS or FFS effect, which do not have the disadvantages indicated above, or only do so to a reduced extent.
  • it must be ensured for monitors and televisions that they also work at extremely high and extremely low temperatures and at the same time have very short response times and at the same time have an improved reliability behaviour, in particular exhibit no or significantly reduced image sticking after long operating times.
  • a reliability parameter which can be specifically influenced here is the voltage holding ratio after exposure to light, such as, for example, exposure to UV light (sun test) or exposure by the backlighting of an LCD.
  • the use of stabilisers of this type increases the voltage holding ratio after exposure to light.
  • the invention thus relates to a liquid-crystalline medium which comprises at least one compound of the formula I and at least one compound from the group of the compounds of the formulae ST-1 to ST-16.

  • Media of this type can be used, in particular, for electro-optical displays having active-matrix addressing based on the ECB effect and for IPS (in-plane switching) displays or FFS (fringe field switching) displays.
  • The principle of electrically controlled birefringence, the ECB effect or also DAP (deformation of aligned phases) effect, was described for the first time in 1971 (M. F. Schieckel and K. Fahrenschon, “Deformation of nematic liquid crystals with vertical orientation in electrical fields”, Appl. Phys. Lett. 19 (1971), 3912). This was followed by papers by J. F. Kahn (Appl. Phys. Lett. 20 (1972), 1193) and G. Labrunie and J. Robert (J. Appl. Phys. 44 (1973), 4869).
  • The papers by J. Robert and F. Clerc (SID 80 Digest Techn. Papers (1980), 30), J. Duchene (Displays 7 (1986), 3) and H. Schad (SID 82 Digest Techn. Papers (1982), 244) showed that liquid-crystalline phases must have high values for the ratio of the elastic constants K3/K1, high values for the optical anisotropy An and values for the dielectric anisotropy of Δε≦−0.5 in order to be suitable for use in high-information display elements based on the ECB effect. Electro-optical display elements based on the ECB effect have a homeotropic edge alignment (VA technology=vertically aligned). Dielectrically negative liquid-crystal media can also be used in displays which use the so-called IPS or FFS effect.
  • Displays which use the ECB effect, as so-called VAN (vertically aligned nematic) displays, for example in the MVA (multi-domain vertical alignment, for example: Yoshide, H. et al., paper 3.1: “MVA LCD for Notebook or Mobile PCs . . . ”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book I, pp. 6 to 9, and Liu, C. T. et al., paper 15.1: “A 46-inch TFT-LCD HDTV Technology . . . ”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 750 to 753), PVA (patterned vertical alignment, for example: Kim, Sang Soo, paper 15.4: “Super PVA Sets New State-of-the-Art for LCD-TV”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 760 to 763), ASV (advanced super view, for example: Shigeta, Mitzuhiro and Fukuoka, Hirofumi, paper 15.2: “Development of High Quality LCDTV”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 754 to 757) modes, have established themselves as one of the three more recent types of liquid-crystal display that are currently the most important, in particular for television applications, besides IPS (in-plane switching) displays (for example: Yeo, S. D., paper 15.3: “An LC Display for the TV Application”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 758 & 759) and the long-known TN (twisted nematic) displays. The technologies are compared in general form, for example, in Souk, Jun, SID Seminar 2004, seminar M-6: “Recent Advances in LCD Technology”, Seminar Lecture Notes, M-6/1 to M-6/26, and Miller, Ian, SID Seminar 2004, seminar M-7: “LCD-Television”, Seminar Lecture Notes, M-7/1 to M-7/32. Although the response times of modern ECB displays have already been significantly improved by addressing methods with overdrive, for example: Kim, Hyeon Kyeong et al., paper 9.1: “A 57-in. Wide UXGA TFT-LCD for HDTV Application”, SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book I, pp. 106 to 109, the achievement of video-compatible response times, in particular on switching of grey shades, is still a problem which has not yet been satisfactorily solved.
  • Industrial application of this effect in electro-optical display elements requires LC phases, which have to satisfy a multiplicity of requirements. Particularly important here are chemical resistance to moisture, air and physical influences, such as heat, infrared, visible and ultraviolet radiation and direct and alternating electric fields.
  • Furthermore, industrially usable LC phases are required to have a liquid-crystalline mesophase in a suitable temperature range and low viscosity.
  • None of the hitherto-disclosed series of compounds having a liquid-crystalline mesophase includes a single compound which meets all these requirements. Mixtures of two to 25, preferably three to 18, compounds are therefore generally prepared in order to obtain substances which can be used as LC phases. However, it has not been possible to prepare optimum phases easily in this way since no liquid-crystal materials having significantly negative dielectric anisotropy and adequate long-term stability were hitherto available.
  • Matrix liquid-crystal displays (MLC displays) are known. Non-linear elements which can be used for individual switching of the individual pixels are, for example, active elements (i.e. transistors). The term “active matrix” is then used, where a distinction can be made between two types:
    • 1. MOS (metal oxide semiconductor) transistors on a silicon wafer as substrate
    • 2. thin-film transistors (TFTs) on a glass plate as substrate.
  • In the case of type 1, the electro-optical effect used is usually dynamic scattering or the guest-host effect. The use of single-crystal silicon as substrate material restricts the display size, since even modular assembly of various part-displays results in problems at the joints.
  • In the case of the more promising type 2, which is preferred, the electrooptical effect used is usually the TN effect.
  • A distinction is made between two technologies: TFTs comprising compound semiconductors, such as, for example, CdSe, or TFTs based on polycrystalline or amorphous silicon. The latter technology is being worked on intensively worldwide.
  • The TFT matrix is applied to the inside of one glass plate of the display, while the other glass plate carries the transparent counterelectrode on its inside. Compared with the size of the pixel electrode, the TFT is very small and has virtually no adverse effect on the image. This technology can also be extended to fully colour-capable displays, in which a mosaic of red, green and blue filters is arranged in such a way that a filter element is opposite each switchable pixel.
  • The term MLC displays here covers any matrix display with integrated non-linear elements, i.e. besides the active matrix, also displays with passive elements, such as varistors or diodes (MIM=metal-insulator-metal).
  • MLC displays of this type are particularly suitable for TV applications (for example pocket TVs) or for high-information displays in automobile or air-craft construction. Besides problems regarding the angle dependence of the contrast and the response times, difficulties also arise in MLC displays due to insufficiently high specific resistance of the liquid-crystal mixtures [TOGASHI, S., SEKIGUCHI, K., TANABE, H., YAMAMOTO, E., SORIMACHI, K., TAJIMA, E., WATANABE, H., SHIMIZU, H., Proc. Eurodisplay 84, September 1984: A 210-288 Matrix LCD Controlled by Double Stage Diode Rings, pp. 141 ff., Paris; STROMER, M., Proc. Eurodisplay 84, September 1984: Design of Thin Film Transistors for Matrix Addressing of Television Liquid Crystal Displays, pp. 145 ff., Paris]. With decreasing resistance, the contrast of an MLC display deteriorates. Since the specific resistance of the liquid-crystal mixture generally drops over the life of an MLC display owing to interaction with the inside surfaces of the display, a high (initial) resistance is very important for displays that have to have acceptable resistance values over a long operating period.
  • There is thus still a great demand for MLC displays having very high specific resistance at the same time as a large working-temperature range, short response times and a low threshold voltage, with the aid of which various grey shades can be generated.
  • The disadvantage of the MLC-TN displays frequently used is due to their comparatively low contrast, the relatively high viewing-angle dependence and the difficulty of generating grey shades in these displays.
  • The market for VA, PS-VA, IPS, FFS and UB-FFS applications is looking for LC mixtures having fast response times and very high reliability. One approach for achieving fast response times is the identification of highly polar LC materials having low rotational viscosities, whose use in LC mixtures facilitates the desired effect. However, the use of highly polar LC materials of this type has an adverse effect on the reliability parameters, in particular after exposure to light.
  • The invention is based on the object of providing liquid-crystal mixtures, in particular for monitor and TV applications, based on the ECB, UB-FFS, IPS or FFS effect, which do not have the disadvantages indicated above, or only do so to a reduced extent. In particular, it must be ensured for monitors and televisions that they also work at extremely high and extremely low temperatures and at the same time have very short response times and at the same time have an improved reliability behaviour, in particular exhibit no or significantly reduced image sticking after long operating times.
  • Surprisingly, it is possible to obtain fast response times of LC mixtures at the same time as good reliability through the use of the compounds of the formula I if suitable stabilisers are added. A reliability parameter which can be specifically influenced here is the voltage holding ratio after exposure to light, such as, for example, exposure to UV light (sun test) or exposure by the backlighting of an LCD. The use of stabilisers of this type increases the voltage holding ratio after exposure to light.
  • The invention thus relates to a liquid-crystalline medium which comprises at least one compound of the formula I and at least one compound from the group of the compounds of the formulae ST-1 to ST-16.
  • The mixtures according to the invention preferably exhibit very broad nematic phase ranges with clearing points 70° C., preferably 75° C., in particular 80° C., very favourable values of the capacitive threshold, relatively high values of the holding ratio and at the same time very good low-temperature stabilities at −20° C. and −30° C., as well as very low rotational viscosity values and short response times. The mixtures according to the invention are furthermore distinguished by the fact that, in addition to the improvement in the rotational viscosity γ1, relatively high values of the elastic constants K33 for improving the response times can be observed. The use of the compounds of the formula I in LC mixtures, preferably having negative dielectric anisotropy, the ratio of rotational viscosity γ1 and elastic constants Ki is reduced.

  • The invention furthermore relates to an electro-optical display having active-matrix addressing based on the dem ECB, VA, PS-VA, PA-VA, IPS, PS-IPS, FFS or PS-FFS effect, characterised in that it contains, as dielectric, a liquid-crystalline medium according to one or more of claims 1 to 16.

  • The expression “have a nematic phase” here means on the one hand that no smectic phase and no crystallisation are observed at low temperatures at the corresponding temperature and on the other hand that clearing still does not occur on heating from the nematic phase. The investigation at low temperatures is carried out in a flow viscometer at the corresponding temperature and checked by storage in test cells having a layer thickness corresponding to the electro-optical use for at least 100 hours. If the storage stability at a temperature of −20° C. in a corresponding test cell is 1000 h or more, the medium is referred to as stable at this temperature. At temperatures of −30° C. and −40° C., the corresponding times are 500 h and 250 h respectively. At high temperatures, the clearing point is measured by conventional methods in capillaries.
  • The liquid-crystal mixture preferably has a nematic phase range of at least 60 K and a flow viscosity ν20 of at most 30 mm2·s−1 at 20° C.
  • The values of the birefringence Δn in the liquid-crystal mixture are generally between 0.07 and 0.16, preferably between 0.08 and 0.13.

  • The liquid-crystal media according to the invention have relatively low values for the threshold voltage (V0). They are preferably in the range from 1.7 V to 3.0 V, particularly preferably ≦2.5 V and very particularly preferably ≦2.3 V.
  • For the present invention, the term “threshold voltage” relates to the capacitive threshold (V0), also called the Freedericks threshold, unless explicitly indicated otherwise.
  • In addition, the liquid-crystal media according to the invention have high values for the voltage holding ratio in liquid-crystal cells.
  • In general, liquid-crystal media having a low addressing voltage or threshold voltage exhibit a lower voltage holding ratio than those having a higher addressing voltage or threshold voltage and vice versa.
  • For the present invention, the term “dielectrically positive compounds” denotes compounds having a Δε>1.5, the term “dielectrically neutral compounds” denotes those having −1.5≦Δε1.5 and the term “dielectrically negative compounds” denotes those having Δε<−1.5. The dielectric anisotropy of the compounds is determined here by dissolving 10% of the compounds in a liquid-crystalline host and determining the capacitance of the resultant mixture in at least one test cell in each case having a layer thickness of 20 μm with homeotropic and with homogeneous surface alignment at 1 kHz. The measurement voltage is typically 0.5 V to 1.0 V, but is always lower than the capacitive threshold of the respective liquid-crystal mixture investigated.
  • All temperature values indicated for the present invention are in ° C.
  • The mixtures according to the invention are suitable for all VA-TFT applications, such as, for example, VAN, MVA, (S)-PVA, ASV, PSA (polymer sustained VA) and PS-VA (polymer stabilized VA).

  • The proportion of component A is preferably between 45 and 100%, in particular between 60 and 100%.
  • For component A, one (or more) individual compound(s) which has (have) a value of Δε≦−0.8 is (are) preferably selected. This value must be more negative, the smaller the proportion A in the mixture as a whole.
  • Component B has pronounced nematogeneity and a flow viscosity of not greater than 30 mm2·s−1, preferably not greater than 25 mm2·s−1, at 20° C.
  • A multiplicity of suitable materials is known to the person skilled in the art from the literature. Particular preference is given to compounds of the formula O-17.
  • Particularly preferred individual compounds in component B are extremely low-viscosity nematic liquid crystals having a flow viscosity of not greater than 18 mm2·s−1, preferably not greater than 12 mm2·s−1, at 20° C.
  • Component B is monotropically or enantiotropically nematic, has no smectic phases and is able to prevent the occurrence of smectic phases down to very low temperatures in liquid-crystal mixtures. For example, if various materials of high nematogeneity are added to a smectic liquid-crystal mixture, the nematogeneity of these materials can be compared through the degree of suppression of smectic phases that is achieved.

Mixtures of this type can be used for so-called polymer-stabilised VA modes (PS-VA) or PSA (polymer sustained VA), in which polymerisation of the reactive mesogens is intended to take place in the liquid-crystalline mixture. The prerequisite for this is that the liquid-crystalline compounds of the LC host do not react under the polymerisation conditions of the reactive mesogens, i.e. generally on exposure to UV in the wavelength range from 320-360 nm. Liquid-crystalline compounds containing an alkenyl side chain, such as, for example, CC-3-V, exhibit no reaction under the polymerisation conditions (UV polymerisation) for the RMs.

  • The liquid-crystal mixtures which can be used in accordance with the invention are prepared in a manner which is conventional per se. In general, the desired amount of the components used in lesser amount is dissolved in the components making up the principal constituent, advantageously 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.
  • By means of suitable additives, the liquid-crystal phases according to the invention can be modified in such a way that they can be employed in any type of, for example, ECB, VAN, IPS, GH or ASM-VA LCD display that has been disclosed to date.
  • The dielectrics may also comprise further additives known to the person skilled in the art and described in the literature, such as, for example, UV absorbers, antioxidants, nanoparticles and free-radical scavengers. For example, 0-15% of pleochroic dyes, stabilisers, such as, for example, phenols, HALS (hindered amine light stabilisers), or chiral dopants may be added. Suitable stabilisers for the mixtures according to the invention are, in particular, those listed in Table C.
  • For example, 0-15% of pleochroic dyes may be added, furthermore conductive salts, preferably ethyldimethyldodecylammonium 4-hexoxybenzoate, tetrabutylammonium tetraphenylboranate or complex salts of crown ethers (cf., for example, Haller et al., Mol. Cryst. Liq. Cryst., Volume 24, pages 249-258 (1973)), may be added in order to improve the conductivity or substances may be added in order to modify the dielectric anisotropy, the viscosity and/or the alignment of the nematic phases. Substances of this type are described, for example, in DE-A 22 09 127, 22 40 864, 23 21 632, 23 38 281, 24 50 088, 26 37 430 and 28 53 728.
  • TABLE B
    Table B indicates possible dopants which can be added to the mixtures according to the invention.

  • WORKING EXAMPLES
  • The following examples are intended to explain the invention without limiting it. In the examples, m.p. denotes the melting point and C denotes the clearing point of a liquid-crystalline substance in degrees Celsius; boiling temperatures are denoted by m.p. Furthermore: C denotes crystalline solid state, S denotes smectic phase (the index denotes the phase type), N denotes nematic state, Ch denotes cholesteric phase, I denotes isotropic phase, Tg denotes glass-transition temperature. The number between two symbols indicates the conversion temperature in degrees Celsius an.
  • The host mixture used for determination of the optical anisotropy Δn of the compounds of the formula I is the commercial mixture ZLI-4792 (Merck KGaA). The dielectric anisotropy Ac is determined using commercial mixture ZLI-2857. The physical data of the compound to be investigated are obtained from the change in the dielectric constants of the host mixture after addition of the compound to be investigated and extrapolation to 100% of the compound employed. In general, 10% of the compound to be investigated are dissolved in the host mixture, depending on the solubility.
  • Unless indicated otherwise, parts or per cent data denote parts by weight or per cent by weight.
  • Above and below:
    • Vo denotes threshold voltage, capacitive [V] at 20° C.,
    • ne denotes extraordinary refractive index at 20° C. and 589 nm,
    • no denotes ordinary refractive index at 20° C. and 589 nm,
    • Δn denotes optical anisotropy at 20° C. and 589 nm,
    • ε denotes dielectric permittivity perpendicular to the director at 20° C. and 1 kHz,
    • ε| denotes dielectric permittivity parallel to the director at 20° C. and 1 kHz,
    • Δε denotes dielectric anisotropy at 20° C. and 1 kHz,
    • cl.p., T(N,I) denotes clearing point [° C],
    • γ1 denotes rotational viscosity measured at 20° C. [mPa·s], determined by the rotation method in a magnetic field,
    • K1 denotes elastic constant, “splay” deformation at 20° C. [pN],
    • K2 denotes elastic constant, “twist” deformation at 20° C. [pN],
    • K3 denotes elastic constant, “bend” deformation at 20° C. [pN],
    • LTS denotes low-temperature stability (nematic phase), determined in test cells.
  • Unless explicitly noted otherwise, all values indicated in the present application for temperatures, such as, for example, the melting point T(C,N), the transition from the smectic (S) to the nematic (N) phase T(S,N) and the clearing point T(N,I), are indicated in degrees Celsius (° C.). M.p. denotes melting point, cl.p.=clearing point. Furthermore, Tg=glass state, C=crystalline state, N=nematic phase, S=smectic phase and I=isotropic phase. The numbers between these symbols represent the transition temperatures.
  • The term “threshold voltage” for the present invention relates to the capacitive threshold (V0), also called the Freedericksz threshold, unless explicitly indicated otherwise. In the examples, as is generally usual, the optical threshold can also be indicated for 10% relative contrast (V10).
  • The display used for measurement of the capacitive threshold voltage consists of two plane-parallel glass outer plates at a separation of 20 μm, which each have on the insides an electrode layer and an unrubbed polyimide alignment layer on top, which cause a homeotropic edge alignment of the liquid-crystal molecules.
  • The display or test cell used for measurement of the tilt angle consists of two plane-parallel glass outer plates at a separation of 4 μm, which each have on the insides an electrode layer and a polyimide alignment layer on top, where the two polyimide layers are rubbed antiparallel to one another and cause a homeotropic edge alignment of the liquid-crystal molecules.
  • The polymerisable compounds are polymerised in the display or test cell by irradiation with UVA light (usually 365 nm) of a defined intensity for a pre-specified time, with a voltage simultaneously being applied to the display (usually 10 V to 30 V alternating current, 1 kHz). In the examples, unless indicated otherwise, a 50 mW/cm2 mercury vapour lamp is used, and the intensity is measured using a standard UV meter (make Ushio UNI meter) fitted with a 365 nm band-pass filter.
  • The tilt angle is determined by a rotational crystal experiment (Autronic-Melchers TBA-105). A low value (i.e. a large deviation from the 90° angle) corresponds to a large tilt here.
  • The VHR value is measured as follows: 0.3% of a polymerisable monomeric compound are added to the LC host mixture, and the resultant mixture is introduced into TN-VHR test cells (rubbed at 90°, alignment layer TN polyimide, layer thickness d≈6 μm). The HR value is determined after 5 min at 100° C. before and after UV exposure for 2 h (sun test) at 1 V, 60 Hz, 64 μs pulse (measuring instrument: Autronic-Melchers VHRM-105).
  • In order to investigate the low-temperature stability, also known as “LTS”, i.e. the stability of the LC mixture to spontaneous crystallisation-out of individual components at low temperatures, bottles containing 1 g of LC/RM mixture are stored at −10° C., and it is regularly checked whether the mixtures have crystallised out.
  • The so-called “HTP” denotes the helical twisting power of an optically active or chiral substance in an LC medium (in μm). Unless indicated otherwise, the HTP is measured in the commercially available nematic LC host mixture MLD-6260 (Merck KGaA) at a temperature of 20° C.
  • Unless explicitly noted otherwise, all concentrations in the present application are indicated in per cent by weight and relate to the corresponding mixture as a whole, comprising all solid or liquid-crystalline components, without solvents. All physical properties are determined in accordance with “Merck Liquid Crystals, Physical Properties of Liquid Crystals”, Status November 1997, Merck KGaA, Germany, and apply for a temperature of 20° C., unless explicitly indicated otherwise.
  • The following mixture examples having negative dielectric anisotropy are suitable, in particular, for liquid-crystal displays which have at least one planar alignment layer, such as, for example, IPS and FFS displays, in particular UB-FFS=ultra-bright FFS), and for VA displays.
