ABSTRACT:
A backlight (lighting device) is arranged on a backside of a liquid crystal panel, and comprises an LED, an optical waveguide, a reflective sheet, and a prism sheet. A diffractive optical element (DOE) constituted of a binary concave and convex pattern is formed in an end surface of the optical waveguide on an LED arranged side.
