ABSTRACT:
An active matrix type liquid crystal display apparatus includes a pair of substrates, a liquid crystal layer, an orientation film, a scanning signal electrode, an image signal electrode, a pixel electrode and an active device, each provided between the liquid crystal layer and one substrate, and a polarizer provided on the outer sides of the substrates, for changing an optical characteristic according to an orientation state of the liquid crystal layer. The electrodes are arranged so as to apply an electric field, mainly parallel to the substrates. At least one of the electrodes is disposed between at least two dielectric layers disposed above and below the at least one of the electrodes, and the resistivity of the liquid crystal layer is set at a value sufficient to substantially prevent disturbance of the orientation of the liquid crystal layer due to static electricity.
