Abstract
A transmissive display device includes: a light source which outputs light; a display part which receives the light from the light source and generates display light representing an image; a deflecting element which changes a direction of the display light emitted from the display part; and a transmissive reflector which reflects, towards a user, light of a wavelength included in the display light emitted from the display part, and transmits light of other wavelengths. An angle formed by a straight line, which extends between an upper edge of an incident area of the display light on the transmissive reflector and a lower portion of an eyebox which is defined as a visible range of the reflected light from the transmissive reflector, with respect to a horizontal line is smaller than a difference between an emission angle and an incident angle of the display light at the transmissive reflector.
