ABSTRACT:
A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.
