Abstract

The present invention relates to a device for laser-processing a light guide plate, which can process a high-quality light guide plate provided with a fine pattern by preventing the deformation of the light guide plate while processing the light guide plate with laser, and comprises a press roller, which comes into contact with the light guide plate and rotates, for pressing the light guide plate to a transfer plate.
