Abstract: A display device according to one aspect of the present invention includes: a display unit configured to have display information and emits visible light having a continuous spectrum; an infrared cut-off part configured to transmit the visible light from the display unit and to reduce the amount of infrared light striking the display unit; and a reflecting part configured to reflect the visible light having passed through the infrared cut-off part. The infrared cut-off part includes a first polymer film and a second polymer film, the first polymer film includes an infrared cut-off layer configured to reduce infrared light transmission, and the second polymer film includes a high-retardation polyester film and is disposed between the first polymer film and the display unit.
