Abstract: A method for cutting a substrate includes: radiating, as part of a first laser radiating process, a laser towards a surface of the substrate to form a first groove in a substrate. Radiating the laser towards the surface includes radiating, in sequence, the laser towards a first outer point (FOP), a second outer point (SOP), a first intermediate point (FIP), a second intermediate point (SIP), and a first cut point (FCP) of the surface, each of the points being spaced apart from one another by one or more distances. The FCP corresponds to a cut line of the substrate. The FOP and the SOP are respectively disposed at lateral sides of the FCP. The FIP is disposed between the FCP and the FOP. The SIP is disposed between the FCP and the SOP. The same kind and intensity of laser is radiated towards each of the points.

Abstract: A laser device includes a light source part; an optical path adjustment part; a light distribution part that splits a laser beam into a plurality of sub-beams to a substrate; a drive part that moves the light distribution part and adjusts relative positions between the light distribution part and the substrate; a sensing part; and a control part. The control part generates an image based on a signal sensed by the sensing part and measures an image contrast of the image. The control part records and compares a plurality of image contrasts according to the position of the light distribution part to determine an optimal position of the light distribution part.
