A surface illumination device suitable for the backlight of a liquid crystal display or the like. For example, a generally L-shaped fluorescent lamp (22) is installed as a light-emitting member on the two edge faces (41c) and (41d) which are adjacent to a generally rectangular light-transmitting plate (21). The corner (40) between the two edges is chamfered. The fluorescent lamp (22) which has an elongated light-emitting part is installed on the light-transmitting plate (21) through an appropriate space to make it possible to execute a high luminance illumination with a low power consumption. Therefore, when a color display is made on a liquid crystal panel, an appropriate high luminance backlight can be implemented. Further, a stable color display is possible because it is little affected by the temperature of the illumination device. <IMAGE> |
