Abstract: A display apparatus includes an insulating layer on a substrate, the substrate including a main through hole, a first groove around and outside the main through hole, and a first test concave portion outside the main through hole, and the insulating layer including a main insulating through hole connected to the main through hole, a first insulating through ring around and outside the main insulating through hole and connected to the first groove, and a first insulating through hole outside the main insulating through hole and connected to the first test concave portion. Along a same width direction: at a same position along the substrate, a width of the first insulating through ring of the insulating layer is less than a width of the first groove of the substrate, and a width of the first insulating through hole is less than a width of the first test concave portion.

Abstract: A display panel inspection system includes a camera to image respective frames of a mother substrate in a frame-by-frame manner, a stage to move the mother substrate relative to the camera, an image obtaining unit to store frames imaged by the camera, a gray level extracting unit that obtains gray level values of the frames, a frame matching unit that searches and matches two frames that match each other among the frames imaged by the camera, a correcting unit that performs correction on one of two frames matched with each other in consideration of an alignment error and an image distortion between the two frames, and a comparing unit that compares the gray level values of the two frames matched with each other, after the correction.
