    Abstract: An electronic device includes a display member including a plurality of display elements and a sensing member including a first sensing pattern disposed on the display member and a second sensing pattern disposed on the display member and capacitively coupled to the first sensing pattern. Each of the first and second sensing patterns includes a plurality of mesh lines to define a plurality of openings. Each of the first and second sensing patterns includes a unit mesh pattern including a central opening and a plurality of peripheral openings surrounding the central opening. A plurality of cutting lines, each of which opens at least two adjacent openings of the plurality of peripheral openings to each other, are defined in the unit mesh pattern. The cutting lines are arranged in a direction surrounding the central opening.
