    摘要: A back-reflection type light diffusing apparatus of this invention is suitable for use in liquid crystal display panels or the like, and is formed by a light guiding plate. The light guiding plate has one surface which forms a first surface through which light is radiated while its opposite surface forms a second surface on which a light reflecting plate is mounted. The light reflecting plate is provided with non-reflecting portions disposed in such a manner that the area thereof increases the closer it gets to the light source so as to radiate light from the light radiating surface uniformly over its entire area.
