Abstract: An organic EL display device includes a first pixel circuit for displaying a first color. The first pixel circuit includes a large light emitting element, a small light emitting element, and a current control circuit that controls whether a current is supplied to the small light emitting element and the large light emitting element or not respectively, and the amount of the current to be supplied to at least one of the small light emitting element and the large light emitting element, according to a tone to be displayed by the first pixel circuit. The current control circuit supplies the current to the small light emitting element if the tone is equal to or smaller than a threshold value, and supplies the current to at least the large light emitting element if the tone is larger than the threshold value.

Abstract: A light-emitting element display device including: a thin film transistor substrate that includes a transistor which controls an amount of light emission from each sub-pixel arranged on an entire display region; and a color filter substrate that is arranged to overlap with the thin film transistor substrate, and includes a color filter which causes a light having a predetermined wavelength region in each sub-pixel to pass. The thin film transistor substrate includes a first light-emitting layer that covers the entire display region and emits a light having one wavelength region, and a second light-emitting layer that emits a light having a wavelength region different from that of the first light-emitting layer, and covers a plurality of independent regions in the display region.
