Abstract:
An electro-optical liquid-crystal display comprising a layer of liquid-crystal medium between two substrates with organic alignment layers on inside surfaces of each of said substrates;the liquid-crystal layer having a twist angle, from one substrate to the other, of 110Â°-360Â°; the liquid-crystal layer having a surface tilt angle of 2Â°-20Â°; and each of said organic alignment layers having a thickness of 3 nm-150 nm, and wherein the difference from 1 of the steepness of the electric-optical characteristic line, represented by the formula V90/V10âˆ’1, is half or less of the corresponding value of an otherwise identical display in which the layer thicknesses of each of the alignment layers is 100 nm.
