摘要
A black-white liquid crystal display (10) contains a nematic liquid crystal with a twist of 270 between cell plates. The product of the liquid crystal layer thickness and anisotropy of the refractive index is about 0.38. A pretilt of about 15 is present. The polarization directions (P1, P2) have an angle of 45 to the orientation directions (Mo, Mu). This display features a very wide viewing angle range with relatively little dependence of the contrast on the viewing angle and there is an almost complete absence of color shift depending on the viewing angle. Due to the significant enhancement in viewing angle range in relation to contrast and color neutrality compared with all known cells, the display is called "Extended Viewing Angle" display (EVA display). It has a very high multiplexability.
