ABSTRACT:
Disclosed herein is a plane lens sheet using a light transmission rate difference, which is used for stereoscopic printing for a lenticular system and an integral photography method and has a plane surface while innumerable lenses are arranged on the surface there so that it looks like a flat transparent sheet, improves the quality of stereoscopic products employing the lens sheet and facilitates the maintenance of the stereoscopic products. The plane lens sheet includes: a concave lens layer 20 and a convex lens layer 30 laminated on each other in such a manner as the adhere to each other with the same radius curvature to form a superposed lens sheet, the concave lens layer 20 and the convex lens layer 30 being made of a transparent synthetic resin and having the same lens pitch and different light transmission rates; a thin flat transparent upper protection layer 10 formed on the concave lens layer 20; a transparent layer 50 formed below the convex lens layer 30 for forming the focal length of the laminated concave lens layer and convex lens layer; and a thin flat transparent lower protection layer 70 formed below the transparent layer 50.
