Abstract: A method of fabricating a display panel is provided. The method includes providing a substrate including a plurality of light emitting elements; forming a first protective layer on a side of the substrate; treating the first protective layer to obtain a first adhesive portion, a second adhesive portion, and a third adhesive portion, the third adhesive portion having an adhesive strength smaller than an adhesive strength of the first adhesive portion, and smaller than an adhesive strength of the second adhesive portion; and removing the third adhesive portion from the substrate to form a bendable portion of the substrate. The bendable portion of the substrate spaces apart a first portion of the substrate from a second portion of the substrate.
