A display device includes a display panel displaying an image. A light source unit provides light to the display panel. A cover member covers a portion of an upper surface of the display panel and a side surface of the display panel. The cover member exposes a display area of the display panel. A thermoelectric device is disposed between the cover member and the light source unit. The thermoelectric device contacts the cover member, and the thermoelectric device generates an electromotive force due to a difference in temperature between the light source unit and the cover member.

A method of driving a display device includes displaying both a natural image and a color vision test image on the display unit. The color vision test image is an image used to determine whether a person has a color vision impairment. A color adjustment user interface for adjusting color of the display unit is displayed on the display unit. A color adjustment instruction that instructs to adjust color of the display unit is received via an input unit. Supply image data supplied to the display unit is adjusted based on the color adjustment instruction by using a controller.
