ABSTRACT:
A liquid crystal display apparatus includes a liquid crystal layer which is disposed in a gap between first and second substrates with long axes of liquid crystal molecules being aligned in one direction, in substantially parallel to substrate surfaces. A plurality of thin film transistors are arranged in row and column directions on an upper side of the first substrate. Pixel electrodes are provided on the upper side of the first substrate to be electrically connected with the thin film transistors. A common electrode is formed on the upper side of the first substrate between the substrate and the liquid crystal layer to correspond to the pixel electrode through an insulating film, and generates an electric filed which controls an alignment direction of the liquid crystal molecules in a plane substantially parallel with the substrate surfaces between itself and the pixel electrode.
