TRANSMISSIVE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/074209
Kind Code:
A1
Abstract:
Disclosed is a transmissive display device provided with a light source which outputs light, a display element which receives the light from the light source and generates display light representing an image, a deflection element which changes the direction of the display light emitted from the display element, and a transmission reflection element which reflects to a user light of wavelengths included in the display light emitted from the display element and transmits light of the other wavelengths therethrough, said transmissive display device being characterized in that the angle which a straight line connecting the upper end portion of a region in which the display light is incident on the transmission reflection element and the lower portion of an eye box defined as a range in which the user can visually recognize the display light reflected by the transmission reflection element forms with the horizon is smaller than the difference between the angle of emission and the angle of incidence of the display light in the transmission reflection element.
