Abstract: A surface-type illumination device suitable for providing backlight in a liquid crystal display is disclosed. For example, an L-shaped fluorescent light can be used as an illuminant and mounted next to two edges of a substantially rectangular light guide plate. The corner of an edge portion between the two edges is removed. The fluorescent light, the length of whose illuminating portion is long, is positioned with an appropriate gap from the light guide plate allowing for illumination with high brightness and low power consumption. Consequently, when the illumination device is used in a color liquid crystal display, appropriate backlight with high brightness can be obtained. Moreover, because the influence of the temperature from the illumination device is small, a stable color display can be achieved.

Abstract: A background lighting apparatus includes a light entering edge surface around substantially the entire periphery of a highly specular transparent plate wherein light beams enter from peripheral light sources and travel toward the central portion of the plate and are dispersed and diffused by a diffusion system formed relative to the transparent plate. Uniformity of luminance provided from the background lighting apparatus is enhanced as a whole by increasing the incident quality of the input light beams into the transparent plate while easing the incident directivity of the light beams on the transparent plate with the overall substantial enhancement of luminance produced from the apparatus. Further, the temperature distribution on a liquid crystal panel positioned adjacent to the output surface of the background lighting apparatus is substantially uniform across the panel so that the transmission quality of the liquid crystal material, which is dependent upon ambient temperatures, is made substantially more uniform resulting in significantly higher levels of uniformity in luminance across the display as well as uniformity of displayed colors and gradations thereof emanating from the display panel.

Abstract: The invention provides a linear organic electroluminescent light source which is high in brightness and capable of realizing white color. A brighter light source can be obtained compared with a light source having only one organic electroluminescent element by forming the organic electroluminescent element to have at least one organic layer, which emits light, on both sides of a transparent substrate, and covering the transparent substrate with a mirror which is high in reflectance except one end face of the transparent substrate. When the same brightness as that of a light source having one element is obtained, the power consumption can be suppressed. The light source can thus emit white light.
