Abstract
An optical element of the present invention includes: a primary surface-whereon diffuse illuminating light radiated by a light source device is incident; a primary surface-formed in a concave cross-sectional shape when viewed from the primary surface-, which reflects only illuminating light incident from the primary surface-; a primary surface-formed in a convex cross-sectional shape when viewed from the primary surface-, which reflects only diffuse illuminating light radiated by the light source device; and a primary surface-which radiates illuminating light incident from the primary surface-and illuminating light reflected by the primary surface-. The primary surfaces-through -are located at positions such that the light beams reflected by the primary surface-and the light beams reflected by the primary surface-are substantially parallel.
