Abstract
A display device has a drain drive circuit, to which a horizontal output enable signal is applied in synchronization with a horizontal scanning signal. The enable signal allows the horizontal scanning signal to be supplied only to the gates of selected sampling transistors. Gate signal lines are also selected by a gate drive circuit. Accordingly, any set of arbitrary pixel elements in the display device are selected for rewriting the signal retained in the pixel elements.
