Claim 6:
7. A display module, comprising:
a plurality of light-emitting elements; and
a sealing element sealing the plurality of light-emitting elements and comprising a base part comprising a transparent material and a cover layer disposed on a surface of the base part,
wherein the cover layer comprises:
a base layer in contact with the surface of the base part;
a plurality of first patterns, each of which contacts and protrudes from the base layer by a first length, and which are spaced apart from each other by a first distance;
a plurality of second patterns, each of which contacts and protrudes from a portion of a corresponding one of the plurality of first patterns by a second length; and
a plurality of third patterns, each of which contacts and protrudes from another portion of a corresponding one of the plurality of first patterns by the second length,
wherein the second patterns do not contact the base part, and the third patterns do not contact the base part,
wherein the first to third patterns form recesses having a first bottom surface formed at a first depth and corresponding to portions of upper surfaces of the first patterns and opposing side surfaces corresponding to one side surface of each of the second and third patterns in the cover layer, form recesses having a second bottom surface formed at a second depth different from the first depth and corresponding to portions below the upper surfaces of the first patterns and opposing side surfaces corresponding to one side surface of each of the second and third patterns in the cover layer, and the bottom surfaces and the opposing side surfaces correspond to an uppermost surface of the cover layer,
wherein the recesses having the first bottom surface and the recesses having the second bottom surface are alternatingly disposed such that, among the first bottom surfaces formed at the first depth and the second bottom surfaces formed at the second depth, each first bottom surface formed at the first depth is directly adjacent to one of the second bottom surfaces formed at the second depth,
wherein a thickness of the cover layer is smaller than a thickness of the base part, and
wherein the second patterns are spaced apart from each other by the same distance, and the third patterns are spaced apart from each other by the same distance.
