Display device, detection device, and watch

A display device comprising:

• a display area that displays an image;
• a first sensor electrode disposed in a peripheral area surrounding the display area;
• a second sensor electrode disposed in the peripheral area and disposed adjacent to the first sensor electrode;
• and
• a detector electrically connected to the first sensor electrode and the second sensor electrode, wherein
• the first sensor electrode and the second sensor electrode both have a body portion and a tapered portion,
• a tapered portion of the first sensor electrode and a tapered portion of the second sensor electrode are disposed to face each other, and
• all the body portions and the tapered portions of the first sensor electrode and the second sensor electrode are disposed along an outer periphery of the display area formed in a curved shape.

A detection device comprising:

• a first sensor electrode;
• a second sensor electrode disposed adjacent to the first sensor electrode;
• and
• a detector electrically connected to the first sensor electrode and the second sensor electrode, wherein
• the first sensor electrode and the second sensor electrode both have a body portion and a comb tooth portion having a plurality of linear electrodes,
• a comb tooth portion of the first sensor electrode and a comb tooth portion of the second sensor electrode are disposed at mutually different locations,
• a body portion of the first sensor electrode is disposed in a first region,
• a body portion of the second sensor electrode is disposed in a second region different from the first region,
• the comb tooth portion of the first sensor electrode and the comb tooth portion of the second sensor electrode are disposed in a third region, which is different from the first region and the second region, and
• areas of the first region, the second region, and the third region are equal.
