Light-emitting element display device

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

• each of the pixels includes
• a first R (red) sub-pixel and a second R sub-pixel each of which emits light in a red wavelength range,
• a first G (green) sub-pixel and a second G sub-pixel each of which emits light in a green wavelength range, and
• a first B (blue) sub-pixel and a second B sub-pixel each of which emits light in a blue wavelength range,
• 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, and
• 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.
