LIGHT DIFFUSION SHEET |
摘要 |
<p>A diffusion sheet which has a flat incident surface and an output surface parallel to the incident surface, and which comprises a sheet body and a plurality of wedge-shaped portions embedded on the output surface side in the sheet body and spreading toward the output surface side. The wedge-shaped portions are lower in refractive index than the sheet body. The side surfaces of the wedge-shaped portions are formed by bent surfaces, and angles formed by respective bent surface on side surfaces and a perpendicular to the incident surface gradually increase toward the output surface side. The tip ends on the incident surface side of wedge-shaped portions have flat surfaces parallel to the incident surface.</p> |
