Abstract
A transmitted light selecting device includes a first light selecting unit having a polarizing filter for allowing an image light ray having one polarization direction to pass therethrough; a phase difference film for providing phase differences to the light ray passing through the polarizing filter to emit light, in which light rays having polarization directions coexist, toward a viewer; a second light selecting unit having a polarizing filter having a polarized light transmission axis perpendicular to that of the polarizing filter; and a phase difference film for providing phase differences to a light ray passing through the polarizing filter to emit light, in which light rays having polarization directions coexist, toward the viewer.
