Abstract:
A multi-domain liquid crystal display comprising:a liquid crystal cell having a first substrate with a plurality of pixel electrodes thereon, a second substrate with a common electrode layer thereon, and liquid crystals filling a space between said substrates; a pair of crossed polarizers being disposed on exterior surfaces of said liquid crystal cell; at least one compensating film being disposed between said crossed polarizers; and a plurality of wall-bump structures being disposed on one of said substrates, each wall-bump structure being located in a pixel area for forming more than one liquid crystal domain resulting from Singe field effect between a pixel electrode and a wall-bump structure in said pixel area; wherein each pixel being substantially rectangular has a longer edge and a shorter edge, and each wall-bump structure comprises a plurality of circular bottom shaped wall-bumps and a plurality of slot shaped wall-bumps, said slot shaped wall-bumps being parallel to the shorter edge of a pixel.
