Abstract
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.
