The plurality of pixels includes a light emitting element and a pixel circuit that drives the light emitting element. The pixel circuit is driven in sets including at least one refresh period and at least one hold period in low frequency driving. The controller controls dynamically the refresh rate during the at least one set when a gradation of an image changes, and simultaneously, changes and supplies a bias voltage during the at least one hold period.
