| description | PROBLEM TO BE SOLVED: To provide a laser cutting apparatus and a method therefor for cutting a two glasses-attached panel for a liquid crystal display panel using a laser beam. SOLUTION: A laser cutting apparatus comprises: a first laser unit for irradiating a first laser beam with a first wavelength along a marked cutting line of an object to be cut; a means for cooling the marked cutting line to which the first laser beam has been irradiated, and thereby generating crack at the cooled cutting line; a second laser unit for irradiating a second laser beam with a second wavelength onto the crack of the marked cutting line; a means for sensing the second laser beam reflected by the crack; and a control means for outputting a signal for correcting a traveling path of the first laser beam by comparing a real cutting line obtained by the sensed signal of the sensing means with the marked cutting line and determining whether the real cutting line deviates from the marked cutting line.
