FRESNEL LENS SHEET WITH REFLECTION SUPPRESSING FILM AND METHOD FOR PRODUCING SAME |
摘要 |
<p>Provided is a Fresnel lens sheet with a reflection suppressing film, which is provided with a Fresnel lens sheet and a reflection suppressing film that is formed on a Fresnel lens surface of the Fresnel lens sheet. The Fresnel lens sheet with a reflection suppressing film has low refractive index in the peripheral portion and can be produced easily. A Fresnel lens sheet (1) with a reflection suppressing film is provided with: a Fresnel lens sheet (10) that has a Fresnel lens surface (12); and a reflection suppressing film (11) that is formed on the Fresnel lens surface (12). The reflection suppressing film (11) is composed of a high refractive index film (11a) and a low refractive index film (11b). The high refractive index film (11a) is formed on the Fresnel lens surface (12). The high refractive index film (11a) has a higher refractive index than the Fresnel lens sheet (10). The low refractive index film (11b) is formed on the high refractive index film (11a). The low refractive index film (11b) has a lower refractive index than the high refractive index film (11a).</p> |
