Claim Text:
1. A light-emitting element display device comprising a light-emitting element display panel that displays an image by light emission of light-emitting regions of a plurality of sub-pixels arranged in each of pixels in a display region, controlled by a driver circuit, wherein the light-emitting element display device includes light-emitting portions that respectively emit lights of R (red), G (green), and B (blue), each of the pixels includes the first R sub-pixel, the first G sub-pixel, and the first B sub-pixel respectively include an R electrode, a G electrode, and a B electrode that control light emission independently of one another in response to the application of potentials, the second R sub-pixel, the second G sub-pixel, and the second B sub-pixel include a W (white) electrode as a common electrode that causes the second R sub-pixel, the second G sub-pixel, and the second B sub-pixel to simultaneously emit lights in response to the application of a potential, the driver circuit includes a sub-pixel control unit that acquires a video signal to calculate a peak luminance in a screen based on the video signal and controls the plurality of sub-pixels based on the peak luminance, the sub-pixel control unit includes the area luminance determining unit further determines the division of areas based on the peak luminance.
