Abstract
In order to improve display quality, a liquid crystal display device includes a video signal supply line for supplying a video signal to signal lines, and a signal line drive circuit which sequentially turns on analog switches connected between the video signal supply line and each signal line. The video signal supply line is branched into a plurality of lines, and the analog switches are connected to the branched video signal supply lines in a distributed manner. The signal line drive circuit consecutively turns on the analog switches connected to different branched video signal supply lines.
