<P>PROBLEM TO BE SOLVED: To reduce a number of processes on cutting laminated glass. <P>SOLUTION: A method for cutting the mother glass substrate 1 of a display panel including a first glass substrate G1 and a second glass substrate G2 laminated together by a sealing material 5 partitioning a plurality of cells arranged in a matrix form is provided. In a first process, a scheduled process line L1 is arranged in a gap between the sealing materials 5 of the adjacent cells, and a laser beam is irradiated along the scheduled process line L1 to form a scribe line on the first glass substrate G1. In a second process, a laser beam is irradiated along the scheduled process line L1 on the second glass substrate G2, and the vicinity of an area 40 to be irradiated by a laser beam is cooled to break the second glass substrate G2. Stress, generated when the second glass substrate G2 is broken, reaches the first glass substrate G1 through the sealing material 5, thereby the first glass substrate G1 is broken along the scribe line at substantially same time with the breakage of the second glass substrate G2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
