MANUFACTURING METHOD FOR LIGHT GUIDE PANEL WITH OPTICAL EFFECT

摘要

A method for manufacturing a light guiding plate is provided to give the eternal optical effect to the light guiding plate and suppress the surface damage of the light guiding plate, by using an optical film having both an optical characteristic and a surface protection performance. A transparent resin plate(201) is extruded by an extruder, and simultaneously polished. An optical film(301) is attached on at least one surface of the transparent resin plate while the polished transparent resin plate is cooled. The optical film has both an optical characteristic and a surface protecting performance. A protective film(211) is attached onto one surface of the transparent resin plate when the optical film is attached onto the other surface of the transparent resin plate.
