ABSTRACT:
Pixel electrodes in the periphery of a thin film transistor array (peripheral part of the display screen) of an active matrix type liquid crystal display device are directly electrically shortcircuited with signal lines, whereby an alternating current signal is always applied to the pixel electrodes without being passed through a thin film transistor as a switching element. Thereby the liquid crystal arranged on the peripheral part of the display screen is driven in a static state resulting in a high stability against the display characteristics.
