Summary:PROBLEM TO BE SOLVED: To provide a light-emitting element display device capable of enhancing the light extraction efficiency, and extracting light with a low power consumption to perform display.SOLUTION: A light-emitting element display device comprises: a thin-film transistor substrate (220) having a transistor for controlling a quantity of light-emission of respective sub-pixels arranged in the whole display region; and a color filter substrate (230) arranged so as to be overlapped with the thin-film transistor substrate, and having a color filter transmitting light in a predetermined wavelength region at the respective sub-pixels. The thin-film transistor substrate comprises: a first light-emitting layer (251) covering the whole display region, and emitting light in one wavelength region; and a second light-emitting layer (252) emitting light in a wavelength region different from that of the first light-emitting layer, and covering a plurality of independent regions in the display region.
