Abstract: A display device incudes: a display panel including a plurality of pixels; and a dimming panel that is disposed between the display panel and a light source of light to be emitted to the display panel and includes a plurality of dimming pixels. When one of the pixels produces an output at highest luminance and the other pixels produce an output at lowest luminance to the display panel, the light is transmitted through a predetermined one of the dimming pixels located on an optical axis of the light that is emitted to the one of the pixels and through the other dimming pixels arranged around the predetermined dimming pixel. A degree of transmission of the light through the other dimming pixels decreases as the light is away along one direction from the predetermined dimming pixel, and there are a plurality of directions having different degrees of the decrease.

Abstract: According to one embodiment, a liquid crystal optical element includes a substrate having a first surface, a plurality of structures disposed on the first surface and arranged at a predetermined pitch, and a liquid crystal layer surrounding each of the structures and interposed between the structures adjacent to each other. The liquid crystal layer has a larger thickness than the structure. The liquid crystal layer has liquid crystal molecules arranged along the structure, and is cured in a state in which an alignment direction of the liquid crystal molecules is fixed.

Abstract: A display device includes a display panel and a light source device. A display period of a frame image includes three subframe periods and an adjusting subframe period. The light source device emits light for reproducing a color corresponding to first chromaticity coordinates in a first subframe period, emits light for reproducing a color corresponding to second chromaticity coordinates in a second subframe period, emits light for reproducing a color corresponding to third chromaticity coordinates in a third subframe period, and emits light for reproducing a differential color in the adjusting subframe period. A chromaticity coordinate area with the first to third chromaticity coordinates as apexes includes chromaticity coordinates of pixel data obtained by excluding partial pixel data from pixel data included in frame image data. The differential color is a complementary color of a mixed color of three colors corresponding to the first to third chromaticity coordinates.
