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.
