Flat type display device and driving method and assembling method therefor

摘要

A display device has a plurality of scanning conductor lines (307) and a plurality of signal conductor lines (308) intersecting the scanning conductor lines (307), a first switching element (304) formed at each intersection between the scanning conductor lines (307) and the signal conductor lines (308), a scanning conductor line drive element (305) for driving the scanning conductor lines, and a signal conductor line drive element (306) for driving the signal conductor lines. A second switching element (309) is provided between each scanning conductor line (307) and the scanning conductor line drive element (305), and the second switching element (309) is put into an open state in synchronization with a fall in level of a video signal given to the signal line (308) to electrically disconnect the scanning conductor line (307) from the scanning conductor line drive element (305).
