An electronic device includes a base member having a touch area defined inside a first closed-shape, the first closed-shape being a first imaginary line, and a peripheral area disposed adjacent to the touch area and defined outside the first closed-shape, and a touch sensor including a plurality of patterns disposed in the touch area to sense a touch from outside and a driving line disposed in the peripheral area and connected to a pattern disposed adjacent to the first closed-shape. The touch area includes a first area defined inside a second closed-shape being a second imaginary line defined in the touch area, and a second area defined outside the second closed-shape and surrounded by the first closed-shape, and an edge pattern disposed in the second area having an area substantially equal to or greater than approximately one-half of an area of a center pattern disposed in the first area.
