VIEW ANGLE-RESTRICTING SHEET AND FLAT PANEL DISPLAY |
| 摘要 |
The view angle-restricting sheet according to the present invention includes an optically functional layer which includes: a plurality of first light transmission sections that are rectangular in cross section and arranged in a multi-stripe fashion; and at least one second light transmission section that is/are rectangular in cross section and arranged between the first light transmission sections, at least one of the lateral face of the first light transmission section and the lateral face of the second light transmission section that face each other being provided as a light-scattering surface having a microstructure including fine protrusions. The arithmetic mean roughness (Ra) of the light-scattering surface is preferably no less than 1.5 μm and no greater than 4 μm. The ratio (Rz/Ra) of the ten-point mean roughness (Rz) to the arithmetic mean roughness (Ra) of the light-scattering surface is preferably no less than 1 and no greater than 20. |
