Detection device

A detection device comprising:

• a substrate;
• and
• a detection electrode including a lower layer portion and an upper layer portion which is on and in physical contact with the lower layer portion, the lower layer portion being between the substrate and the upper layer portion,
• wherein the upper layer portion has a first region, a second region, and a third region, the first and second regions being located continuously, the third region being a different region from the first and second regions,
• the first region overlaps the lower layer portion in a plan view,
• the second region protrudes from the first region, does not overlap the lower layer portion in a plan view, and is not in physical contact with any conductive member in the thickness direction,
• the first and second regions are covered with a protective film, and
• the third region is not covered with the protective film.

A detection device comprising:

• a substrate;
• a detection electrode including a lower layer portion and an upper layer portion which is on and in physical contact with the lower layer portion, the lower layer portion being between the substrate and the upper layer portion;
• and
• a flexible printed circuit with a terminal,
• wherein the upper layer portion has a first region and a second region which are located continuously,
• the first region overlaps the lower layer portion in a plan view,
• the second region protrudes from the first region,
• the detection electrode has a portion which is a part of the detection electrode and does not include the second region,
• the portion includes an entirety of the detection electrode in a thickness direction of the detection electrode, and
• the terminal overlaps the lower layer portion and the upper layer portion in a plan view.
