Abstract

A liquid crystal display of the present invention includes: a pair of substrates, at least one of which is transparent; a liquid crystal layer being interposed between said pair of substrates; electrodes for applying an electric field to liquid crystals molecules in said liquid crystal layer; active switching elements connected with said electrodes; an alignment film being formed on a surface of at least one of said pair of substrates, said surface being contacted with said liquid crystal layer; and an optical device for controlling a transmission of light in cooperation with alignment of said liquid crystal molecules in each pixel, said means being located on at least one said pair of substrates; wherein an aligning direction of each liquid crystal molecule in each pixel is ranged between −2 degrees to +2 degrees with respect to an average aligning direction &thgr;1c of said liquid crystal layer.
