A method for repairing a display device including a defective pixel area where a failure has occurred includes irradiating a first laser beam to a first interface provided between a first layer and a second layer that contact each other corresponding to the defective pixel area to form a protrusion-depression surface in one or more surfaces of the first layer and the second layer that form the first interface; and irradiating a second laser beam to the protrusion-depression surfaces provided in one or more surfaces of the first and second layers to burn the protrusion-depression surface.
