Zusammenfassung:	PURPOSE: A method of manufacturing a light guide plate using a roll to roll process is provided to attach an optical waveguide to a pet film in a roll to roll method, thereby improving a working speed. CONSTITUTION: A light guide plate master is manufactured by forming a pattern on material. A stamper is manufactured using the light guide plate master. A photo-curable molding resin is provided on a PET(30) or a PC film. The pattern is transferred on the photo-curable molding resin through a roll to roll process using the stamper. A PSA(Pressure Sensitive Adhesive) or a UV adhesive is coated on one side of a PMMA plate. A molding resin in which the pattern is transferred is loaded. The molding resin is pressurized/attached by upper and lower parts of rubber rolls in a roll to roll method.
