Abstract
Provided herein may be a display device. The display device may include a first substrate including a first substrate having a plurality of pixel areas; a second substrate having a second base substrate facing the first substrate, first to third color filters provided on the second base substrate, the first to third color filters being respectively disposed on locations corresponding to respective pixel areas of the plurality of pixel areas and embodying different colors, and an infrared sensor disposed between the plurality of pixel areas in a plan view and configured to sense infrared light; a liquid crystal layer disposed between the first substrate and the second substrate; and a backlight unit configured to provide single-color light to the liquid crystal layer. At least one of the first to third color filters may include infrared quantum dot material which converts light provided from the backlight unit into infrared light.
