Touch sensor and display device having the same

A display device comprising:

• a display panel to display an image;
• and
• a touch sensor disposed on the display panel, wherein the touch sensor includes:
• a base layer including first and second sensing regions adjacent to each other in a first direction and a non-sensing region surrounding at least one side of each of the first and second sensing regions;
• first sensors disposed in each of the first and second sensing regions, the first sensors being arranged along the first direction, the first sensors being electrically connected to each other along the first direction;
• second sensors disposed in each of the first and second sensing regions, the second sensors being arranged along a second direction, the second sensors being electrically connected to each other along the second direction;
• and
• at least one third sensor located in the first sensing region and the second sensing region,
• wherein the at least one third sensor includes first and second sub-sensor patterns spaced apart from each other at a boundary between the first sensing region and the second sensing region, and the first and second sub-sensor patterns have substantially the same size,
• wherein the first sub-sensor pattern includes a first sub-electrode located in the first sensing region, a second sub-electrode located in the second sensing region, and a first part connecting the first and second sub-electrodes, and
• wherein the second sub-sensor pattern includes a third sub-electrode located in the second sensing region, a fourth sub-electrode located in the first sensing region, and a second part connecting the third and fourth sub-electrodes.

A touch sensor for a display device comprising:

• a base layer including first and second sensing regions adjacent to each other in a first direction and a non-sensing region surrounding at least one side of each of the first and second sensing regions;
• first sensors disposed in each of the first and second sensing regions, the first sensors being arranged along a second direction intersecting the first direction, the first sensors being electrically connected to each other along the second direction;
• second sensors disposed in each of the first and second sensing regions, the second sensors being arranged along the first direction, the second sensors being electrically connected to each other along the first direction;
• and
• at least one third sensor located in the first sensing region and the second sensing region,
• wherein the at least one third sensor includes first and second sub-sensors electrically separated at a boundary between the first sensing region and the second sensing region, and the first and second sub-sensors have substantially the same size,
• wherein the first sub-sensor has a shape converging toward the center of the third sensor and extending back and forth between the first sensing region and the second sensing region, and
• wherein the second sub-sensor has a shape converging toward the center of the third sensor and extending back and forth between the second sensing region and the first sensing region.
