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.
