Abstract
A laser processing method that can reduce warpage occurring in a glass and reduce a stress generated on the glass at a time of releasing a protective material from the glass. The laser processing method includes: forming the protective materials on both surfaces of the glass; processing the glass by radiating a laser beam onto the glass together with the protective materials after the protective material formation; and releasing the protective materials from the glass after the laser processing.
