Display device including connective wirings within a display area thereof

1. A display device, comprising:

a substrate including a display area, a peripheral area at least partially surrounding the display area, and a pad area within the peripheral area;

a plurality of data lines disposed within the display area; and

a plurality of connection wirings disposed within the display area, connected to the plurality of data lines, and configured to transmit a data signal from the pad area to the plurality of data lines,

wherein the plurality of connection wirings are disposed in a different layer from a layer in which the plurality of data lines are disposed,

wherein each of the plurality of connection wirings comprises a plurality of branches that protrude from the connection wirings in a direction perpendicular to a direction in which the connection wirings are primarily extended, and

wherein the display area comprises a first area in which the plurality of connection wirings extend in a first direction, and a second area in which the plurality of connection wirings extend in a second direction that is perpendicular to the first direction.

2. The display device of claim 1 , wherein, in the first area, each of the plurality of connection wirings comprises a plurality of first branches that extend from the connection wirings in the second direction, and in the second area, each of the plurality of connection wirings comprises a plurality of second branches that extend from the connection wirings in the first direction.

3. The display device of claim 2 , wherein, the first branches that extend towards each other from two adjacent connection wirings from among the plurality of connection wirings are disposed in a same line in the first area, and the second branches that extend towards each other from two adjacent connection wirings from among the plurality of connection wirings are disposed in a same line in the second area.

4. The display device of claim 3 , wherein, the two adjacent connection wirings and the first branches that extend towards each other from the two adjacent connection wirings define first unit patterns in the first area, the two adjacent connection wirings and the second branches that extend towards each other from the two adjacent connection wirings define second unit patterns in the second area, and each of the first unit patterns and each of the second unit patterns have equal areas.

5. The display device of claim 4 , wherein the display area further comprises a third area that is a remaining area of the display area excluding the first area and the second area, wherein the third area comprises the first unit patterns or the second unit patterns, and the first unit patterns or the second unit patterns included in the third area are in floating states.

6. The display device of claim 3 , wherein the first area further comprises first cover patterns that at least partially overlap ends of the first branches extending towards each other in the first direction, and the second area further comprises second cover patterns that overlap ends of the second branches protruding towards each other in the second direction.

7. The display device of claim 3 , wherein, in the first area, each of the plurality of connection wirings comprises a plurality of first slices that are spaced apart from each other in the first direction, and a plurality of bridges electrically connect the plurality of first slices to one another.

8. The display device of claim 7 , wherein the plurality of first branches protrude from the plurality of first slices, and the display device further comprises dummy bridges that at least partially overlap each other in a direction perpendicular to the ends of the first branches.

9. The display device of claim 3 , wherein, in the second area, each of the plurality of connection wirings comprises a plurality of second slices that are spaced apart from each other in the second direction, and a plurality of bridges electrically connecting the plurality of second slices to one another.

10. The display device of claim 9 , wherein the plurality of second branches protrude from the plurality of second slices, and the display device further comprises dummy bridges that overlap one another in a direction perpendicular to the ends of the second branches.

11. The display device of claim 1 , wherein the display device further comprises a thin film transistor and a light-emitting device electrically connected to the thin film transistor, and

wherein the plurality of connection wirings are disposed between the thin film transistor and the light-emitting device.
