Definitions
- the present invention relates to benzochrome derivatives, preferably mesogenic benzochrome derivatives, in particular liquid crystalline
- liquid crystal displays in particular liquid crystal displays (AMDs or AM LCDs according to English “active matrix addressed liquid crystal displays”) and very particularly so-called VAN (English “veritcally aligned nematics”) liquid crystal displays, an embodiment of ECB ( from English “electrically controlled birefringence”) liquid crystal displays in which nematic liquid crystals with a negative dielectric anisotropy ( ⁇ ) are used.
- liquid crystal displays In such liquid crystal displays, the liquid crystals are used as dielectrics, the optical properties of which change reversibly when an electrical voltage is applied.
- Electro-optical displays that use liquid crystals as media are known to the person skilled in the art. These liquid crystal displays use various electro-optical effects. The most common of these are the TN effect (English “twisted nematic”), with a homogeneous, almost planar output orientation of the liquid crystal director and a nematic structure twisted by approx. 90 °, the STN effect (English “super-twisted nematic”) and the SBE effect (English "supertwisted birefringence effect” with a 180 ° or more twisted nematic structure). These and similar electro-optical effects use liquid-crystalline media with positive dielectric anisotropy ( ⁇ ).
- ⁇ dielectric anisotropy
- the recently used I PS effect (English “in plane switöhing") can use both dielectrically positive and dielectrically negative liquid crystal media, similar to "guest / hosf advertisements", ie the guest / host advertisements, the dyes depending on the related Display mode can be used either in dielectric positive or in dielectric negative media.

- Various semiconductor materials predominantly silicon, but also cadmium selenide, are used in the TFTs.
- Amorphous silicon or polycrystalline silicon is used in particular.
- liquid crystal displays with an electric field perpendicular to the liquid crystal layer and liquid crystal media with negative dielectric anisotropy ( ⁇ ⁇ 0) are preferred.
