    Abstract: A light-emitting element display device includes a light-emitting element display panel that displays an image by light emission of light-emitting regions of a plurality of sub-pixels. Each of the pixels includes a first R sub-pixel, a second R sub-pixel, a first G sub-pixel, a second G sub-pixel, a first B sub-pixel and a second B sub-pixel. The second R sub-pixel, the second G sub-pixel, and the second B sub-pixel include a W 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 calculates a peak luminance in a screen based on the video signal and controls the plurality of sub-pixels based on the peak luminance.

    Abstract: An organic EL display device includes: a lower electrode; an upper electrode; a first organic layer which is disposed between the lower electrode and the upper electrode and is formed of a plurality of layers including a light emitting layer formed of an organic material that emits light; a metal wire that extends between the pixels within the display region; and a second organic layer which is formed of a plurality of layers the same as that of the first organic layer and which comes into contact with a part of the metal wire and does not come into contact with the first organic layer. The upper electrode comes into contact with the metal wire in the periphery of the second organic layer. Accordingly, it is possible to uniformise the potential of the upper electrode without reducing the light emission area.
