Abstract
An optical element includes a plurality of mirrors; a first transmittance member interposed between adjacent two mirrors; and a second transmittance member provided on one of an incidence and an exit side of the image and the external image with respect to the first transmittance member. A surface of one transmittance member opposite to the other transmittance member among the first and the second transmittance member is an incidence surface on which the image and the external image are incident via a light guiding body. A surface of the other transmittance member is an exit surface from which the image and the external image are exited. Each of the plurality of mirrors is disposed so as to be inclined with respect to the incidence surface. The plurality of mirrors include a first and a second mirror whose width is narrower than a width of the first mirror.
