Touch sensing apparatus, touch panel, and display apparatus including the same

A touch panel comprising:

• a substrate;
• a plurality of first touch electrodes disposed on the substrate to extend along a first direction and arranged along a second direction that crosses the first direction;
• a plurality of second touch electrodes, a plurality of third touch electrodes, and a plurality of fourth touch electrodes positioned on the substrate to be arranged along the first direction;
• a first insulating layer disposed on the first touch electrode, the second touch electrode, and the third touch electrode;
• and
• a second insulating layer disposed on the fourth touch electrode,
• wherein the first insulating layer and the second insulating layer have different dielectric constants.

A display device comprising:

• a display panel configured to display an image;
• and
• a touch panel including a first electrode, a second electrode, a third electrode, and a fourth electrode arranged on the display panel, a first insulating layer disposed on the first electrode, the second electrode, and the third electrode, and a second insulating layer disposed on the fourth electrode,
• wherein a first material included in the first insulating layer and a second material included in the second insulating layer have different dielectric constants.
