DIFFUSION SHEET AND BACKLIGHT UNIT USING THE SAME |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a diffusion sheet excellent in isotropic diffusion effect of light. <P>SOLUTION: The diffusion sheet has an inner diffusion sheet which comprises diffusion elements in a matrix resin, wherein the ratios (Gmax/Gmin) of the maximum value Gmax to the minimum value Gmin of 60° luminance on both side surfaces of the sheet are less than 1.1 in both and the minimum value Gmin of the luminance on at least half side surface is 1 to 50. <P>COPYRIGHT: (C)2007,JPO&INPIT |
