Abstract
An active matrix type liquid crystal display apparatus has a pair of substrates, at least one of the substrates being transparent; a liquid crystal layer arranged between the pair of substrates; and electrode structure for generating an electric field having a dominant component parallel to a surface of the substrate and passing through the liquid crystal layer, the electrode structure being formed on one of the pair of substrates; a pair of alignment layers formed on respective surfaces in contact with the liquid crystal layer of the pair of substrates; and a pair of polarizing plates arranged so as to sandwich the pair of substrates, wherein the glass transition temperature Tg of a boundary surface between said liquid crystal layer and the alignment layer is higher than the nematic-isotropic phase transition temperature T(N−I) of a liquid crystal composite forming the liquid crystal layer.
