Touch panel and electronic device

An electronic device comprising:

• a display panel having a display surface;
• and
• a touch panel located above the display surface, the touch panel comprising:
• a substrate;
• a plurality of first electrode series disposed on the substrate, each of the plurality of first electrode series comprising a plurality of first electrode portions and a plurality of first connection portions, each of the plurality of first connection portions connecting adjacent two of the plurality of first electrode portions in series in a first direction;
• and
• a plurality of second electrode series disposed on the substrate, each of the plurality of second electrode series comprising a plurality of second electrode portions and a plurality of second connection portions, each of the plurality of second connection portions connecting adjacent two of the plurality of second electrode portions in series in a second direction, wherein the first direction intersects the second direction, and each of the plurality of first connection portions partially overlaps one of the plurality of second connection portions,
• wherein the plurality of first electrode portions and the plurality of second electrode portions are disposed in parallel on the substrate, and an entirety of an area of each of the plurality of second electrode portions is larger than an entirety of an area of each of the first electrode portions,
• wherein the entirety of the area of each of the plurality of second electrode portions is 2±0.2 times the entirety of the area of each of the first electrode portions.
