Writing periods and lighting periods are alternately provided in one frame period for at least one color. Each writing period is a period in which part of a pixel signal is written to a corresponding one of the pixels. Each lighting period is a period in which light is emitted to the pixel after a corresponding one of the writing periods. A light amount in at least one of the lighting periods is larger than a light amount in other lighting periods.
