<P>PROBLEM TO BE SOLVED: To provide a light diffusing sheet which is excellent in heat resistance and dimensional stability and which does not lower performance of other optical members and has excellent display grade. <P>SOLUTION: The light diffusing sheet comprises at least a transparent resin (a) and a glass fiber (b), surface 10 points average roughness (Rz) of at least one surface is ≥3μm and ≤100μm and mean spacing (Sm) between ruggedness is ≥0.1μm and ≤5μ. Otherwise the light diffusing sheet whose surface 10 points average roughness (Rz) of one surface is ≥3μm and ≤100μm, mean spacing (Sm) between ruggedness is ≥0.1μm and ≤50μm, surface 10 points average roughness (Rz) of an opposite surface is <3μm and mean spacing (Sm) between ruggedness of the opposite surface is ≥50μm, is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
