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.

摘要： A backlight (illumination device; 2) of the present invention includes: multiple light sources (5); and multiple light guides (7, 17, . . . ) for causing surface emission of light from the light sources (5). Each of the light guides (7, 17, . . . ) includes: a light-emitting section (7b, 17b, . . . ) having a light-emitting surface (7a); and a light guide section (7c) for guiding, to the light-emitting section (7b, 17b, . . . ), light from the light sources (5), a light-emitting section (7b) of a first light guide (7) being provided above a light guide section (17c) of a second light guide (17) adjacent to the first light guide (7). A light amount adjusting section (11) for reducing the amount of light incident on it is provided between the light-emitting section (7b) of the first light guide (7) and the light-emitting section (17b) of the second light guide. This allows for production of an illumination device having further improved luminance uniformity.

摘要： A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).

摘要： An illumination device for a flat panel display may include a light-guiding member for guiding light from a light-emitting lamp, wherein the light-emitting lamp has a light-emitting device incorporated in a lamp body, wherein the lamp body has a reflection surface that reflects light from the light-emitting device and an emitting surface that is opposite to the reflection surface and irradiates the reflected light from the reflection surface toward the light-guiding member. In certain example embodiments, the emitting surface is formed into a shape along the irradiated surface of the light-guiding member and the reflection surface is formed to be curved such that the reflected light is made approximately parallel seen from one direction upon reflecting the light from the light-emitting device.
