Display device employing a time-division-multiplexed driver

A display device includes sub-pixels, video lines, a drive circuit and switch groups. The video lines are divided into plural blocks each composed of m video lines, m being an integer of 2 or more. The drive circuit outputs m gray scale voltages time-sequentially. Each of the switch groups corresponding to one of the blocks is composed of first to mth switches, receives the m gray scale voltages from the drive circuit, and then supplies them to the m video lines in a time-division multiplexed fashion. The mth switch is turned on last during a writing time for writing the m gray scale voltages into the sub-pixels, and Tq
