DISPLAY DEVICE

摘要

A display device includes an image display area that includes pixels sectioned by scanning signal lines and video signal lines, first scanning connection lines connected to scanning signal lines, first thin film transistors, first selection signal lines, second thin film transistors, second selection signal lines, and a scanning signal drive circuit connected to the first scanning connection lines, the first selection signal lines, and the second selection signal lines, wherein the scanning signal drive circuit sequentially supplies a pulse signal to the first scanning connection lines in a selection period in which a gate-on voltage is applied to the one of the first selection signal lines, and the scanning signal drive circuit applies a gate-off voltage to the one of the second selection signal lines corresponding to the one of the first selection signal lines to which the gate-on voltage is applied.
