A wavefront lens sheet, a display front plate and a transmissive projection screen (LENTICULAR LENS SHEET, DISPLAY FRONT PLATE AND TRANSMISSION TYPE PROJECTION SCREEN)

摘要

The present invention relates to a corrugated lens sheet having a substrate layer and a lens portion in the form of a corrugated lens formed on the light incident surface side of the substrate so as to be convex and an achromatic or chromatic colored layer formed adjacent to at least the light incident surface of the lens portion The substrate may not be colored or may be colored thinner than the colored layer. It is possible to restrict the reflection of external light by using the above-mentioned equipment, and it is possible to enhance the contrast of images without greatly reducing the intensity of the image light, and it is possible to perform good image pitching.
