PROBLEM TO BE SOLVED: To attain a display apparatus wherein fogging occurring on a deflection unit in front of the eyes of a user is reduced, eliminated and prevented, while suppressing the increase in the volume, weight and component cost of the apparatus as a whole. SOLUTION: The display apparatus includes light sources 101 and 110 which emit a beam, including visible light forming an image and infrared rays; and transmissive deflection units 104 and 107, including a first surface facing the eyes of the user and a second surface which is a rear surface of the first surface. The transmissive deflection units 104 and 107 have transmissive characteristics for transmitting the visible light, from the second surface side to the first surface side, deflection characteristics for deflecting toward the eyes of the user, the visible light projected from the light sources 101 and 110 to the first surface side, and infrared absorption characteristics for absorbing the infrared rays projected from the light sources 101 and 110 to the first surface side.
