Abstract: Used is a display device having: a support; first and second image light source units mounted on the support; a first half mirror mounted on the support and having a first reflecting surface inclined with respect to an emitting direction of light of the first image light source unit; and a second half mirror mounted on the support and having a second reflecting surface inclined with respect to an emitting direction of light of the second image light source unit. The light emitted from the first image light source unit is reflected by the first reflecting surface and irradiated in a first direction, and the light emitted from the second image light source unit is reflected by the second reflecting surface and irradiated in a second direction different from the first direction. The same image or a different image can be simultaneously displayed at the first and second display regions.
