A laser repair method and device for removing impurities (30) on a substrate (20) includes steps: obtaining an initial position (S1) of an impurity (30) on the substrate (20); bombarding impurities (30) (S2) at the initial position; detecting whether there are residual impurities (32) (S3) at the peripheral position of the substrate (20) centered on the initial position; and if the peripheral position surrounds the initial position; With residual impurities (32), the residual impurities (32) (S4) located at the periphery are bombarded.
