1. An illumination device for a flat panel display comprising:

  • a light-guiding member for guiding light emitted from a light-emitting lamp, whereinthe light-emitting lamp comprises a light-emitting device at least partially embedded in a lamp body comprising resin;

    whereinthe 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, wherein the light-emitting device is located between the reflection surface of the lamp body and the light-guiding member;

    whereinthe emitting surface is formed to have a shape along the irradiated surface of the light-guiding member; and

    the reflection surface is formed to be curved in a lateral dimension extending parallel to a plane of the light-guiding member such that the reflected light becomes approximately parallel as it proceeds toward the light-guiding member after being reflected by the reflection surface; and

    wherein the light-emitting device is at least partially embedded in the lamp body at a side thereof at or proximate the emitting surface so that the light-emitting device is closer to the emitting surface of the lamp body than to the reflection surface of the lamp body.
