<P>PROBLEM TO BE SOLVED: To provide a method for dividing a glass plate, by which a glass plate having a reinforcing layer formed thereon is divided along a set division scheduled line without deteriorating the quality of the glass plate. <P>SOLUTION: The method for dividing the glass plate 2 having the reinforcing layer 21 formed thereon comprises cutting the glass plate 2 along a set division scheduled line by a cutting blade 623. The method includes: a reinforcing layer removing process for removing the reinforcing layer 21 in areas exceeding the thickness of the cutting blade 623 along the division scheduled line by irradiating the reinforcing layer 21 formed on the surface of the glass plate 2 with a laser beam along the set division scheduled line; and a cutting process comprising positioning the cutting blade 623 on the areas 23 where the reinforcing layer 21 of the glass plate 2 subjected to the reinforcing layer removing process is removed, and relatively moving the cutting blade 623 and the glass plate 2 while rotating the cutting blade 623 to cut the glass plate 2 along the division scheduled line where the reinforcing layer 21 is removed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
