a first support part disposed below the display panel, a groove being defined in a top surface of a portion of the first support part overlapping the folding part, and the first support part being foldable about the folding part; a second support part disposed in the groove, wherein the first support part has a specific gravity less than a specific gravity of the second support part; and a cover layer disposed in the groove and below the second support part. ### Claim 2 (depends on 1) The display device of claim 1, wherein the first support part comprises: a first sub support part disposed below the first non-folding part and a first portion of the folding part adjacent to the first non-folding part; and a second sub support part disposed below the second non-folding part and a second portion of the folding part adjacent to the second non-folding part, the groove is defined in top surfaces of the first and second sub support parts overlapping the folding part in a plan view. ### Claim 3 (depends on 2) The display device of claim 2, wherein the groove is further defined in top surfaces of the first and second sub support parts overlapping the portions of the first and second non-folding parts adjacent to the folding part in a plan view. ### Claim 4 (depends on 2) The display device of claim 2, wherein the first sub support part comprises: a 1-1-th sub support part disposed below the first non-folding part and having a first thickness; and a 1-2-th sub support part disposed below the first portion and having a second thickness less than the first thickness, the second sub support part comprises: a 2-1-th sub support part disposed below the second non-folding part and having the first thickness; and a 2-2-th sub support part disposed below the second portion and having the second thickness. ### Claim 5 (depends on 4) The display device of claim 4, wherein a top surface of the 1-2-th sub support part is stepped to be lower than a top surface of the 1-1-th sub support part, a top surface of the 2-2-th sub support part is stepped to be lower than a top surface of the 2-1-th sub support part, and bottom surfaces of the 1-1-th, 1-2-th, 2-1-th, and 2-2-th sub support parts are defined on a same surface. ### Claim 6 (depends on 4) The display device of claim 4, wherein the 1-1-th sub support part and the 1-2-th sub support part are integrated with each other, and the 2-1-th sub support part and the 2-2-th sub support part are integrated with each other. ### Claim 7 (depends on 2) The display device of claim 2, wherein the cover layer overlaps a space between the first sub support part and the second sub support part in a plan view. ### Claim 8 (depends on 1) The display device of claim 1, wherein a dummy groove overlapping the folding part in a plan view is defined in a bottom surface of the cover layer. ### Claim 9 (depends on 1) The display device of claim 1, wherein openings extending in a second direction and arranged in the first direction are defined in the second support part. ### Claim 10 (depends on 9) The display device of claim 9, wherein the cover layer overlaps the openings in a plan view. ### Claim 11 (depends on 1) The display device of claim 1, further comprising: a third support part disposed on a top surface of the first support part and a top surface of the second support part which overlap the first and second non-folding parts, wherein the third support part has a hardness greater than a hardness of the first support part and less than a hardness of the second support part. ### Claim 12 (depends on 1) The display device of claim 1, wherein the first support part and the second support part are integrated with each other, and openings extending in a second direction and arranged in the first direction are defined in the second support part overlapping the folding part in a plan view. ### Claim 13 (depends on 12) The display device of claim 12, further comprising: a first auxiliary support part disposed below the cover layer and connected to a side of the first support part; and a second auxiliary support part disposed below the cover layer and connected to another side of the first support part, wherein the first auxiliary support part and the second auxiliary support part are spaced apart from each other in the first direction. ### Claim 14 (depends on 13) The display device of claim 13, wherein each of the first and second auxiliary support parts has a thickness less than a difference in thickness between the first support part and the second support part. ### Claim 15 (depends on 13) The display device of claim 13, wherein each of the first auxiliary support part and the second auxiliary support part and each of the first support part and the second support part have a same specific gravity. ### Claim 16 (depends on 13) The display device of claim 13, further comprising: a first cushion layer disposed below the first support part and overlapping the first non-folding part in a plan view;
