PROBLEM TO BE SOLVED: To provide a display device excellent in operability.SOLUTION: A display device comprises: a transmission screen; a video light source disposed on light-entering side of the transmission screen and projecting video light onto the transmission screen; an infrared light source projecting infrared light onto the transmission screen; infrared light detection means detecting reflected infrared light of the infrared light emitted from the infrared light source; information processing means performing arithmetic processing on the basis of a shape pattern of the infrared light detected by the infrared light detection means; and operating means including a plurality of members having different shapes, disposed in contact with or proximate to a light-emission surface of the transmission screen, and reflecting the infrared light. The transmission screen includes: a transparent base material layer; a plurality of unit-light transmission units disposed on one surface of the base material layer and arranged in a direction along the surface of the base material layer; and a plurality of unit-light absorption units disposed between the light transmission units, absorbing visible light, and transmitting the infrared light. |
