Abstract: A display device includes: a display panel with pixels; a dimming panel with dimming pixels; and a light source. When a pixel is controlled to be lit in white and a predetermined condition is satisfied, a blurring region is formed, and light from the light source is transmitted through the blurring region and the pixel. When a pixel is controlled to be lit up in white and the predetermined condition is not satisfied, the blurring region is not formed, the dimming pixel 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. The predetermined condition is satisfied when the pixel controlled to be lit in white is at a predetermined distance or farther from an outer edge of a display area.

Abstract: Each of a plurality of timing controllers has a synchronization reference signal output terminal from which a synchronization reference signal is output and a synchronization reference signal input terminal to which the synchronization reference signal is input. A master timing controller outputs a predetermined signal of display signals which are input from an external device, from the synchronization reference signal output terminal of the master timing controller as the synchronization reference signal, and the synchronization reference signal is input to the synchronization reference signal input terminals of the master timing controller and a slave timing controller. Accordingly, a luminance difference can be prevented from occurring between divided regions of a display panel due to asynchronization between display signals input to respective timing controllers in a display device in which a plurality of timing controllers are used and the display panel is divided into a plurality of regions.
