A method for repairing and inspecting a display device include transferring a light-emitting element onto the panel substrate; positioning the inspection substrate on the panel substrate such that the contact pins of the inspection substrate face the light-emitting element; connecting the contact pins to the light-emitting element and applying a voltage to the contact pins to identify whether or not the light-emitting element emits light and thus is defective or normal; upon determination that the light-emitting element is defective, replacing the defective light-emitting element with a normal light-emitting element; and connecting a wiring electrode to the normal light-emitting element.
