Abstract
A method for manufacturing a light guide plate (LGP) stamper (26) includes the steps of: forming a photo-resist film (21) on a substrate (30); exposing and developing the photo-resist film to form micro patterns (21′); etching the substrate by means of a dry etching method to form a perform including the stamper; and stripping off residual patterns from the substrate to form the LGP stamper.
