Abstract
In a display device having a non-rectangular display panel, when the display panel is divided into a rectangular region and a non-rectangular region by a boundary line extending in a same direction as scanning lines, light emission control lines are driven so that a length of a first non-light emission period in which pixel circuits in each row in the rectangular region are in a non-light emission state and a length of a second non-light emission period in which the pixel circuits in each row in the non-rectangular region are in the non-light emission state are different. With this, a luminance difference that occurs near a boundary between the rectangular region and the non-rectangular region is suppressed, and display quality is improved.
