ABSTRACT:
A planar illumination unit includes an optical guide layer for guiding light therethrough and emitting the light from a top surface, a light source fixture provided so as to face a side wall of the optical guide layer for injecting a light into the optical guide layer, an optical scattering layer disposed above the top surface of the optical guide layer for causing a scattering in the light that has been received from the optical guide layer, and a reflector provided on a bottom surface of the optical guide layer for reflecting the light incident to the optical guide layer, wherein the light source fixture includes a reflector for reflecting the light that has been produced by a light source in a direction primarily offset from the light source.
