Document Type and Number:
WIPO Patent Application WO/2010/140397
Kind Code:
A1
Abstract:
A plurality of low refractive index material-exposed portions (23) having the same area and a plurality of high refractive index material-exposed portions (22) having different areas are mixed and arranged on an emission surface (11U) of a light emission angle adjusting sheet (11). In particular, a low refractive index material (13) has a shape having a width which monotonously decreases toward a light receiving surface (11B) side.
