Abstract
Pseudo-impulse display for reducing after-images during display of moving images in an active matrix type display apparatus. Liquid crystal capacitors are formed at intersections of signal lines and scanning lines to display images. Auxiliary capacitors are provided for keeping a potential difference across the liquid crystal capacitors during display. One of the two electrodes of the auxiliary capacitors is connected to a switching element together with a pixel electrode. After the liquid crystal capacitor and the auxiliary capacitor have been charged with a video signal on the signal lines while the switching element is selectively put into the conducting state with the scanning lines, and after a predetermined time has passed, an auxiliary capacitor driver applies a signal to the other electrode of the auxiliary capacitor, such that the display luminance due to the liquid crystal capacitor is reduced.
