ABSTRACT:
An optical element includes a transparent substrate having a main surface, a first birefringent photosensitive film arranged on a first region of the main surface such that a slow axis or a fast axis is aligned with a prescribed first direction, and a second birefringent photosensitive film formed on a second region different from the first region of the main surface such that the slow axis or the fast axis is aligned with a prescribed second direction different from the first direction. The first and second directions are different by 90.degree. (.+-.20.degree., more preferably, .+-.10.degree.). An image display device employing the optical element further includes an image forming device such as a liquid crystal display device, and with the optical element arranged on an image display screen, stereoscopic imaging is possible.
