Abstract: According to one embodiment, a display device includes a first power supply line, a second power supply line, a reset line, pixels, gate lines, control wiring lines, source lines, a first driver and a second driver. Each of the pixels includes a drive transistor, a light emitting element, a pixel switch, a storage capacitor and a reset switch. The reset switch is connected between the reset line and a gate electrode of the drive transistor, and switched between an ON state and an OFF state by a second control signal provided via a corresponding control wiring line among the control wiring lines.

Abstract: A display device includes: a display unit including sub-pixels; and a signal processor. The sub-pixels are arranged such that either a first sub-pixel or a third sub-pixel is between a second sub-pixel and a fourth sub-pixel arranged in one direction. The signal processor outputs output signals to assign, to a set of the sub-pixels included in the display unit, color components assigned to two pieces of pixel data arranged in the one direction in input signals. The set of the sub-pixels is made up of the first, second, third, and fourth sub-pixels. The signal processor assigns a first color component that is a part or the whole of a white component in one of the two pieces of the pixel data to the fourth sub-pixel and second color components other than the first color component in the two pieces of the pixel data to the first to third sub-pixels.

Abstract: According to an aspect, a display device includes: a display panel including a display area provided with pixels; an illuminator including an illumination area configured to emit light to the display panel such that the display area is illuminated from one surface side of the display panel; and a liquid crystal dimming panel overlapping the display panel, and including a dimming area configured to be adjusted in transmittance of the light emitted to another surface side of the display panel through the display area. The illumination area includes first segment regions configured such that luminance levels thereof are individually adjusted. The dimming area includes second segment regions configured such that the light transmittances thereof are individually adjusted. Each of the first segment regions overlaps more than one of the second segment regions. Each of the second segment regions overlaps more than one of the pixels.
