Zusammenfassung:PURPOSE: A light guide plate processing method with a laser and a light guide plate using the same are provided to conveniently manufacture an engraved line having a fixed pitch and width according to the size of the light guide plate. CONSTITUTION: An engraved line(111) is formed using a laser beam on an acryl plate(100) of a light guide plate. The pitch and a width of the engraved line are always fixed regardless of the distance from a light source part. A depth of the engraved line gradually decreases toward the light source part.
