PURPOSE: To provide a method and an apparatus for correcting a defect capable of enhancing correction efficiency by correcting laser welding through a beam waste system. CONSTITUTION: A laser beam 16 from a laser irradiation mechanism 1 is corrected into a beam waste state with a correcting lens 19. The image of the corrected laser beam 16 is formed through an image formation lens 18 to irradiate the portion of a luminescent spot defect through an objective lens 15, so that electrodes are corrected, or shortcircuited, by laser welding.
