Abstract
A head mount display apparatus includes display section; eyepiece optical member for guiding light from display section to eyeball of wearer of the apparatus; and support substrate for supporting eyepiece optical member, support substrate being formed in a shape corresponding to outer shape of edge surfaces of eyepiece optical member and integrated with eyepiece optical member. Herein, edge surfaces of eyepiece optical member include plural slant surfaces in contact with support substrate. The plural slant surfaces include: light reflecting slant surface for reflecting light from display section toward eyeball of wearer, formed such as to be closer to an optical axis, as farther from an eyepiece surface and closer to surface opposite to eyepiece surface; and slant surface, other than reflecting slant surface, formed such as to be farther from the optical axis, as farther from eyepiece surface and closer to surface opposite to eyepiece surface.
