A light-emitting array substrate allowing a higher efficiency in the seating of numerous very small light source elements includes a substrate, an insulating layer on the substrate including positioning holes, and light-emitting elements. Each positioning hole penetrates the insulating layer and forms a first opening and a second opening. For each positioning hole, a size of the bottommost first opening is less than a size of the topmost second opening, and, from topmost to bottommost of the substrate, a projection of the second opening on the substrate more than covers a projection of the first opening on the substrate. A method of fabricating the substrate and a display panel using the substrate are further disclosed.
