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.
