MANUFACTURING METHOD OF STAMPER FOR LIGHT GUIDE PLATE

摘要

A method for manufacturing a stamper for a light guide plate is provided to increase accuracy of a lens pattern by forming a molding pattern by molding balls corresponding to the lens pattern and to form intaglio and/or relief lens patterns by properly regulating the volume of the molding balls for placing grooves. A method for manufacturing a stamper for molding a light guide plate having plural lens patterns comprises the steps of: forming plural placing grooves(11) on the plane of an original plate(10) of the stamper; placing molding balls(20) in each placing groove; and forming molding patterns(21) corresponding to the lens patterns by heating, melting, and hardening the molding balls. The placing grooves have regular or irregular intervals, and the same or irregular size.
