Abstract:
The present application provides a display device that easily reduces an incident amount of an infrared light to a display portion on the basis of maintaining visual confirmation of display information. A display device according to one scheme of the present disclosure comprises: a display portion emitting a visible light of a linearly polarized wave having display information; an infrared light cut-off portion transmitting the visible light from the display portion and reducing an incident amount of an infrared light to the display portion; and a reflecting portion reflecting the visible light transmitted from the infrared light cut-off portion, wherein the infrared light cut-off portion comprises an infrared light cut-off layer, the infrared light cut-off layer has a slow axis, and the slow axis is generally parallel to a vibration direction of the linearly polarized wave.
