Abstract
A head-mounted display apparatus includes a cross dichroic prism including four triangular prisms that are mutually bonded, and a first dichroic film and a second dichroic film provided between adjacent prisms of the four triangular prisms, a plurality of display panels arranged respectively opposite to a plurality of light incident planes of the cross dichroic prism, and a projection optical system configured to project light emitted from the cross dichroic prism onto a pupil of a user. The cross dichroic prism includes an optically imperfect part at a center of a bonded part of the four triangular prisms. A ratio between an aerial conversion length from each of light-emission planes of the plurality of display panels to the center of the bonded part, and a width of the optically imperfect part, is greater than or equal to 250:1.
