1. A display module, comprising:
a plurality of light-emitting elements; and
a sealing element sealing the plurality of light-emitting elements,
wherein the sealing element comprises:
a base part comprising a transparent material; and
a cover layer in contact with a surface of the base part,
wherein the cover layer comprises a plurality of first patterns, each of which is engraved in an intaglio manner to a first depth, and a plurality of second patterns, each of which is engraved in the intaglio manner to a second depth different from the first depth,
wherein the first patterns form recesses having a bottom surface formed at the first depth and opposing side surfaces in the cover layer, the second patterns form recesses having a bottom surface formed at the second depth and opposing side surfaces in the cover layer, and the bottom surfaces and the opposing side surfaces correspond to an uppermost surface of the cover layer,
wherein the first patterns and the second patterns are alternatingly disposed such that, among the bottom surfaces formed at the first depth and the bottom surfaces formed at the second depth, each bottom surface formed at the first depth is directly adjacent to one of the bottom surfaces formed at the second depth,
wherein the first patterns do not contact the base part, and the second patterns do not contact the base part,
wherein a thickness of the cover layer is smaller than a thickness of the base part, and
wherein the first patterns are spaced apart from each other by the same distance, and the second patterns are spaced apart from each other by the same distance.
