Touch sensor and display device with touch sensor

A touch sensor comprising:

• first electrodes;
• second electrodes;
• third electrodes;
• an inorganic insulation layer below the first electrodes, the second electrodes, and the third electrodes;
• and
• a buffer layer between the first electrodes and the second electrodes, wherein
• two of the first electrodes are connected via a first connection part in a first direction, and
• two of the second electrodes are connected via a second connection part in a second direction differing from the first direction.

A display device comprising:

• a pixel electrode;
• a light-emitting element above the pixel electrode;
• a counter electrode above the light-emitting element;
• an inorganic insulation layer above the counter electrode;
• first electrodes above the inorganic insulation layer;
• second electrodes above the inorganic insulation layer;
• third electrodes above the inorganic insulation layer;
• and
• a buffer layer between the first electrodes and the second electrodes, wherein
• two of the first electrodes are connected via a first connection part in a first direction, and
• two of the second electrodes are connected via a second connection part in a second direction differing from the first direction.
