Touch panel, display panel, and display unit

A touch sensor device comprising:

• a substrate;
• and
• a detection electrode on the substrate,
• the detection electrode including an extending part, a first linear part with a first end, a second linear part with a second end, the first linear part and second linear part extending in a first direction, first connecting parts directly connecting the first linear part with the extending part, and second connecting parts directly connecting the second linear part with the extending part, wherein
• the first linear part and the second linear part are arranged in the first direction, separated from each other, and located at a same side of the extending part, and
• a distance between the first end and the second end is smaller than a length of one of the first connecting part and the second connecting part.

A touch sensor device comprising:

• a substrate;
• and
• a detection electrode on the substrate, the detection electrode including
• a base linear part,
• a first annular shape, and
• a second annular shape,
• wherein
• the first annular shape includes
• the base linear part,
• a first linear part, and
• first connecting parts connecting the first linear part with the base linear part,
• the second annular shape includes
• the base linear part,
• a second linear part, and
• second connecting parts connecting the second linear part with the base linear part,
• the first linear part and the second linear part are located at a same side of the base linear part,
• the first linear part has a first protrusion protruding from the first annular shape toward the second linear part,
• the second linear part has a second protrusion protruding from the second annular shape toward the first linear part, and
• a first end of the first protrusion is separated from a second end of the second protrusion, and
• a distance between the first end and the second end is smaller than a distance of the first linear part and the base linear part.
