Abstract
A display device includes unit cells, each including a thin film transistor and a pixel, arrayed in a matrix form on a display board. First switching elements are provided at intersections between signal conductor lines and scanning conductor lines, scanning conductor line drive elements driving the scanning conductor lines. Finally, second switching elements are included, one provided between each scanning conductor line and scanning conductor line drive element. Each second switching element is put into an open state in synchronization with a fall in level of an input video signal provided to a signal conductor line to electrically disconnect the corresponding scanning conductor line from the scanning conductor line drive element. Thus, the scanning conductor line drive element is not affected by instantaneous voltage drop on the corresponding scanning conductor line.
