Abstract:
1. A liquid crystal display device comprising: a plurality of source lines; a plurality of display pixels, each of which is connected to an associated one of the plurality of source lines; an output driver which outputs a non-video signal which is common to the plurality of source lines in a non-video signal write period and a video signal, which is independent of the non-video signal, in association with each of the plurality of source lines in a video signal write period; a selection switch circuit which is connected between the plurality of source lines and the output driver; and a controller which controls the output driver and the selection switch circuit, wherein the non-video signal write period includes a period to provide the non-video signal to the plurality of source lines simultaneously, the controller is configured to control the selection switch circuit such that the non-video signal is supplied to the plurality of source lines in parallel, and a timing of an end of a supply of the non-video signal is varied between the plurality of source lines.
