发明名称 LIGHT DIFFUSING SHEET AND BACK LIGHT FOR LIQUID CRYSTAL DISPLAY
摘要 <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 &ge;3&mu;m and &le;100&mu;m and mean spacing (Sm) between ruggedness is &ge;0.1&mu;m and &le;5&mu;. Otherwise the light diffusing sheet whose surface 10 points average roughness (Rz) of one surface is &ge;3&mu;m and &le;100&mu;m, mean spacing (Sm) between ruggedness is &ge;0.1&mu;m and &le;50&mu;m, surface 10 points average roughness (Rz) of an opposite surface is <3&mu;m and mean spacing (Sm) between ruggedness of the opposite surface is &ge;50&mu;m, is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI
