摘要： An optical system according to an embodiment of the present invention includes a reflective imaging element having a first principal face which is struck by light emitted from a display panel, a second principal face parallel to the first principal face, and two mutually-orthogonal specular elements being perpendicular to the first principal face, and causes an image displayed on a display surface of the display panel to form an image at a position of planar symmetry with respect to the reflective imaging element as a plane of symmetry. A transparent substrate which is disposed on at least either the first principal face side or the second principal face side of the reflective imaging element is further included, and first light striking the transparent substrate is linearly polarized light, with a large proportion of p-polarized light.
