Abstract

See full text

A display device includes light sources that emit light, a display panel that displays an image, and a light guide panel that guides the light emitted from the light sources to the display panel. The light guide panel includes an incident surface facing the light sources, an emission surface facing the display panel, a first reflective surface facing the incident surface, and a second reflective surface facing the emission surface. The first reflective surface has a concave shape that reflects light so that the reflected light becomes closer to parallel light when viewed in a facing direction of the display panel and the light guide panel in the light guide panel, is tilted at an angle larger than 0 degrees with respect to the incident surface, and intersects the second reflective surface at an angle smaller than 90 degrees.
