A liquid crystal display device which includes a plurality of OCB liquid crystal pixels arrayed substantially in a matrix, and a driver circuit which cyclically writes a non-video signal and a video signal as a pixel voltage in each of the liquid crystal pixels. The liquid crystal display device further includes a control circuit which sets a first period and a second period different in length from the first period such that a total time length of the first period and the second period does not exceed one frame period, and controls the driver circuit to execute write of the non-video signal for the liquid crystal pixels in the first period and to execute write of the video signal for the liquid crystal pixels PX in the second period.
