Abstract
A display device includes a display panel, an illumination device, and a control unit, in which, when performing display in a first display mode, the control unit corrects an image signal to generate a correction signal, writes a first image based on the correction signal in the display panel, leaves a second light source unlit, and selectively turns on a plurality of first light sources based on the correction signal, and when performing display in a second display mode, the control unit generates a correction signal, writes a first image in the display panel, leaves the second light source unlit, and selectively turns on the plurality of first light sources based on the correction signal, in a first display period, and writes a second image based on the image signal in the display panel and turns on at least the second light source, in a second display period.
