Patent ID: 8411013

Claim:
A liquid crystal display device comprising: a plurality of liquid crystal pixels which are arrayed substantially in a matrix; a driver circuit which cyclically writes a non-video signal and a video signal to each of the plurality of liquid crystal pixels as pixel voltages; and a control circuit which controls an operation timing of the driver circuit, wherein the control circuit sets, in one frame period, a first period which is shorter than the one frame period, a second period which partly overlaps the first period and is shorter than the one frame period, and a third period which partly overlaps the second period and is shorter than the one frame period, and the control circuit is configured to execute control of the driver circuit such that write of the non-video signal in the plurality of liquid crystal pixels is executed in the first period, write of the video signal in the plurality of liquid crystal pixels is executed in the second period, write of the same video signal as the video signal, which is written in the second period, in the plurality of liquid crystal pixels is executed in the third period, the write of the non-video signal and the write of the video signal are alternately executed in units of one horizontal cycle or a plurality of horizontal cycles in a period in which the first period overlaps the second period, and the write of the video signal corresponding to the second period and the write of the video signal corresponding to the third period themselves overlap and are alternately executed in units of one horizontal cycle or a plurality of horizontal cycles in a period in which the second period overlaps the third period.
