METHOD FOR MOLDING INNER REFLECTIVE BODY AND MOLD FOR MOLDING INNER REFLECTIVE BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for molding an inner reflective body such as a light guiding plate with no weldline and excellent optical characteristics. SOLUTION: When the inner reflective body which takes a light from a light source into a molded body and then, reflects the light from the light source on the inside of the surface of the molded body and emits this reflected light from the other surface of the molded body and consists of a transparent resin molded body is molded, a mold in which the molding surface of at least one mold between a pair of the molds comprises an air-permeable porous metal and molding is performed by injection molding.
