Abstract: A display device includes a display area including a plurality of pixels, and a gradation control circuit configured to control a gradation of the pixel based on a gradation control mode. Each of the plurality of pixels includes first and second LED chips. One frame period of the gradation control mode includes a first to third subframe periods. In the first subframe period, the gradation of the pixel is controlled by a light emitting area of each of the first and second LED chips. In the second subframe period, the gradation of the pixel is controlled by a light emission time of each of the first and second LED chips. In the third subframe period, the gradation of the pixel is controlled by a current value supplied to each of the first and second LED chips.
