Abstract
In a normally black double cell, grey scale enhancement is obtained by dividing pixels in the driving cell into sub-pixels which are rotated preferably through 180° with respect to each other.
Claims5
A liquid crystal display device having, between a polarizer and an analyzer, a first layer of twisted liquid crystal material with a twisted structure between two transparent substrates, with pixels being realized between the substrates, and a compensator layer disposed directly on one of the transparent substrates and having a twisted structure with a twist opposite to that of the first layer of liquid crystal material, wherein a pixel has at least two sub-pixels and at least a part of an insulating and/or orientation layer associated with said pixel is provided such that the direction of orientation is substantially 180° different in said at least two sub-pixels.
