Abstract
A liquid crystal display apparatus include a pair of substrates, a liquid crystal layer arranged between the pair of substrates; a plurality of electrodes formed on one substrate, and an alignment control layer formed on a face of at least one of the pair of substrates and being in contact with the liquid crystal layer. An optical characteristic is charged in response to a molecular alignment condition of the liquid crystal layer, and the thickness of the liquid crystal layer is set to a substantially constant thickness by spacers. A surface of the alignment control layer on the at least one of the pair of substrates which is in contact with the liquid crystal layer has stepped difference portions and on a surface formed in a display pixel, an inclination degree of a stepped difference portion in said alignment control layer is less than 1.
