1. A display device comprising:
a display panel comprising a plurality of pixels;
a dimming panel that is disposed so as to face the display panel on one surface side of the display panel and comprises a plurality of dimming pixels; and
a light source configured to emit light that travels from the dimming panel toward the display panel, wherein
when any of the pixels is controlled to be lit up in white in accordance with an input image signal, and a predetermined condition is satisfied, a blurring process is applied so that more than one of the dimming pixels transmit light, a blurring region is formed that is a region including the dimming pixels to which the blurring process is applied, and light from the light source is transmitted through the blurring region and the pixel and emitted to another surface side of the display panel,
when any of the pixels is controlled to be lit up in white in accordance with the input image signal and the predetermined condition is not satisfied, the blurring region is not formed, any of the dimming pixels located in a position overlapping the pixel on a straight line along a direction in which the display panel faces the dimming panel is controlled to transmit light, and light from the light source is transmitted through the dimming pixel and the pixel and emitted to the other surface side of the display panel, and
the predetermined condition is satisfied when the pixel that is controlled to be lit up in white is at a predetermined distance or farther from an outer edge of a display area provided with the pixels on the display panel.
