OPTICAL FILM AND SURFACE LIGHT SOURCE USING IT |
| 摘要 |
<p>An optical film (10) comprising a transparent base film (11) made of polyethylene terephthalate (PET), a prism made of photo-curing resin such as acryl modified epoxy and formed on an incident surface (12), one surface of the base film (11), and a hologram made similarly of photo-curing resin and formed on an output surface (13) facing the incident surface (12), wherein the prism totally reflects an incident light off a groove or a ridge having an almost triangular sectional shape to thereby bend the light in a direction perpendicular to the output surface (13), and the hologram diffuses the light output from the output surface (13) anisotropically to enhance luminance.</p> |
