Abstract

The present invention relates to a device for laser-processing a light guide plate having a cleaning means for eliminating particles from the end portion of a laser beam irradiation unit, which is in closest proximity to the light guide plate to be processed, and comprises: a frame; a laser oscillation unit for generating a laser beam; the laser irradiation unit for receiving the laser beam from the laser oscillation unit and irradiating same, while being transferred back and forth along a line on the frame, for forming a predetermined pattern on the light guide plate; and the cleaning means for removing particles from the end portion of the laser beam irradiation unit which is in closest proximity to the light guide plate, wherein the cleaning means further comprises a duct having one surface open toward the end portion of the irradiation unit, a cleaning brush which is rotatably installed inside the duct and arranged so that one side comes into contact with the end portion of the irradiation unit, and a cleaning motor for actuating the cleaning brush.
