To provide a device for correction of defects and a method for correcting defects to make high quality correction possible without giving damages on the corrected face.

After an air cylinder 15 is stroked to the lowest end, a Z-axis table 3 is driven at a low speed to a preliminarily determined distance to lower a scratch needle 19 to nearly touch an electrode pattern 22 or a glass substrate 21. While the air cylinder 15 is kept at the lowest end, the Z-axis table 3 is lifted, a slider 17 is brought into contact with a stopper 20, and an X-axis table and Y-axis table 2 are driven to operate the scratch needle 19 in the horizontal direction to remove a defect.
