Abstract: An electronic device includes a first electrode, a second electrode, and a third electrode. The first electrode includes a first boundary side extending in a direction. The second electrode includes a second boundary side extending in the direction. The third electrode is disposed between and spaced apart from the first electrode and the second electrode. The third electrode includes a first side facing the first boundary side and a second side facing the second boundary. The first side and the second side have shapes that are asymmetric to each other with respect to a center axis extending in the direction.
