Original Abstract Submitted
In a display device, a display panel displays a first image in a first image region in a display region. An illuminance sensor detects illuminance of incident light. The backlight includes multiple light sources arranged in a matrix. The plurality of light sources include a first light source group constituted by at least one light source that overlaps the first image region, and a first peripheral light source group constituted by at least one light source located on the periphery of the first light source group. The control circuit allows the backlight to turn on the first light source group when the illuminance is less than a first threshold. The control circuit allows the backlight to turn on the first light source group and at least one light source of the first peripheral light source group, when the illuminance is greater than or equal to the first threshold.
