Abstract: A display panel inspecting apparatus includes a first inspecting transistor including a control electrode for receiving a first test gate signal, an input electrode for receiving a first voltage and an output electrode connected to an outermost data line disposed in an outermost area of a display region of a display panel, a second inspecting transistor including a control electrode for receiving the first test gate signal, an input electrode for receiving a second voltage and an output electrode connected to a normal data line disposed out of the outermost area of the display region, and a third inspecting transistor including a control electrode for receiving the first test gate signal, an input electrode for receiving a third voltage and an output electrode connected to a module crack inspecting data line disposed out of the outermost area of the display region.

Abstract: 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.
