Abstract:
An organic light emitting diode display device includes a substrate including a red pixel region, a green pixel region, and a blue pixel region; a driving thin film transistor and a light emitting diode which are in each of the red pixel region, the green pixel region, and the blue pixel region; and a cholesteric liquid crystal (CLC) layer having an infrared radiation (IR) wavelength in a transmission direction of light emitted from the light emitting diode, wherein the IR wavelength is in a range of 800 nm to 1,100 nm, and the CLC layer has a reflection wavelength of 400 nm to 700 nm at a viewing angle of 40° to 60°.
