Abstract
A display apparatus including display system and imaging systems for left-eye and right-eye and displaying an image of outside acquired by each of the imaging systems, the display system comprises display element, and optical element comprising incident surface, two reflection surfaces and exit surface. The display apparatus comprises limiting unit limiting light beam width so that light beam entering second pupil located behind the exit pupil does not satisfy diameter of the second pupil. When the second pupil is set at a position on an optical axis 10 mm away on an opposite side of the optical element with respect to the exit pupil, the limiting unit limits the light beam width such that at least a part of the light beam of an outermost peripheral angle of view on an outer side in the horizontal direction does not reach an evaluation pupil diameter of the second pupil.
