Abstract
An optical element includes partially reflecting mirrors provided in parallel to each other with an interval therebetween, reflect a part of image light and external light, and transmit another part of the image light and the external light; and a transmitting member interposed between adjacent two partially reflecting mirrors of the partially reflecting mirrors. The light-transmissive member includes an incidence surface on which the image light and the external light are incident and an exit surface from which the image light and the external light are exited. Each of the partially reflecting mirrors is disposed to be inclined with respect to the incidence surface and the exit surface. The partially reflecting mirrors include at least one first partially reflecting mirror and at least one second partially reflecting mirror having different reflectances with respect to predetermined polarized light components included in the image light and the external light.
