LIGHT-EMITTING ELEMENT, ILLUMINATION DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A light-emitting element (11) of the present invention includes: a light source (5a); a light guide (7) having a light-emitting surface (7a); and a maintaining section (10), the light source (5a) having directivity which causes components of the light travel in a first direction, which is parallel to the light-emitting surface (7a), to be more than those in a direction perpendicular to the light-emitting surface (7a), the light guide (7) having a light-receiving surface for receiving the components of the light traveling in the first direction, the maintaining section (10) being provided in a first region, indicative of a lowest level of luminance, on the light-emitting surface (7a) in a case where luminance over the light-emitting surface (7) is divided into a plurality of levels between a low luminance and a high luminance. This makes it possible to produce a light-emitting element and an illumination device each of which has improved uniformity of the luminance over the light-emitting surface.
