wherein the second mesh pattern comprises a second mesh line extending in the first direction.

3 . The display device of claim 2 , wherein each of the mesh patterns further comprises a third mesh line extending in a second direction crossing the first direction, and having a third width that is less than the second width.

4 . The display device of claim 3 , wherein the emission areas comprise:

first emission areas configured to emit first color light;

second emission areas configured to emit second color light different from the first color light, and alternately arranged with the first emission areas along the second direction; and

third emission areas configured to emit third color light different from the first color light and the second color light, and spaced apart from the first emission areas and the second emission areas in the first direction.

5 . The display device of claim 4 , wherein the connection area overlaps at least a portion of the third emission areas in the second direction.

6 . The display device of claim 4 , wherein the first mesh pattern is between one of the first emission areas and one of the second emission areas adjacent thereto,

wherein adjacent pairs of the third emission areas define emission area pairs spaced from each other by a first distance in the second direction, and

wherein two adjacent ones of the emission area pairs are spaced from each other a second distance in the second direction that is greater than the first distance with the second mesh pattern therebetween.

7 . The display device of claim 6 , wherein the second mesh pattern comprises:
