Abstract:
1. A liquid crystal display device comprising a pair of substrates, at least one of which is transparent; a nematic liquid crystal layer between the pair of substrates; a group of interdigitated electrodes formed on at least one of the substrates and adapted to apply an electric field to said liquid crystal layer, wherein the electric field has a component substantially parallel to the surfaces of the substrates; and an alignment layer disposed between the nematic liquid crystal layer and at least one of the substrates, wherein the alignment layer has been subjected to liquid crystal anchoring treatments in plural directions to form a plurality of liquid crystal in-plane anchoring directions, the plurality of liquid crystal in-plane anchoring directions of the alignment layer form substantially equal angles relative to one another on the corresponding substrate surface, a pretilt angle in each of the liquid crystal anchoring directions with respect to the corresponding substrate surface is substantially zero.
