Abstract

A display device including a display area and a non-display area, the display device including a plurality of data wires disposed in the display area and in the non-display area, a plurality of connecting wires disposed in the display area and connected to the data wires, a plurality of dummy patterns disposed in the display area in the same layer as the connecting wires, and shielding patterns disposed on the connecting wires. First gaps are defined between the connecting wires and the dummy patterns, and the shielding patterns overlap with the first gaps.

Claims (38)

1. A display device including a display area and a non-display area, the display device comprising:

first touch electrodes disposed in the display area and arranged in a first direction;

second touch electrodes disposed in the display area and arranged in a second direction that intersects the first direction;

connecting electrodes connecting the first touch electrodes;

a plurality of data wires disposed in the display area and in the non-display area;

a plurality of connecting wires connected to the data wires;

dummy patterns disposed in the same layer as the connecting wires; and

a plurality of pixels disposed in the display area,

wherein:

first gaps are defined between the connecting wires and the dummy patterns; and

the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the first gaps.

2. The display device of claim 1 , further comprising

a pixel-defining layer defining the pixels,

wherein the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the pixel-defining layer.

3. The display device of claim 1 , wherein:

the dummy patterns comprise first dummy patterns which are disposed between the connecting wires and second dummy patterns which are separated from the first dummy patterns;

second gaps are defined between the first dummy patterns and the second dummy patterns; and

the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the second gaps.

4. The display device of claim 3 , wherein:

the display area includes a first area in which the connecting wires are disposed and a second area which accounts for the rest of the display area: and

the dummy patterns further comprise third dummy patterns which are disposed in the second area and fourth dummy patterns which are separated from the third dummy patterns.

5. The display device of claim 4 , wherein:

third gaps are defined between the third dummy patterns and the fourth dummy patterns: and

the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the third gaps.

6. The display device of claim 1 , wherein:

the connecting wires comprise a plurality of protruding wire patterns which are projected from first sides of the connecting wires;

fourth gaps are defined between the protruding wire patterns; and

the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the fourth gaps.

7. The display device of claim 6 , wherein:

the protruding wire patterns comprise first protruding wire patterns which are projected in a first direction and second protruding wire patterns which are projected in the opposite direction of the first direction; and

the fourth gaps are disposed between the first protruding wire patterns and the second protruding wire patterns.

8. The display device of claim 6 , wherein:

the protruding wire patterns comprise third protruding wire patterns which are projected in a second direction that intersects the first direction and fourth protruding wire patterns which are projected in the opposite direction of the second direction; and

the fourth gaps are disposed between the third protruding wire patterns and the fourth protruding wire patterns.

9. The display device of claim 6 , wherein:

the dummy patterns comprise sixth dummy patterns and first protruding dummy patterns and second protruding dummy patterns which are both projected from the sixth dummy patterns;

fifth gaps are defined between the first protruding dummy patterns and the second protruding dummy patterns; and

the first touch electrodes, the second touch electrodes, and the connecting electrodes overlap with the fifth gaps.
