Abstract: A touch sensor includes a base layer including a sensing area and a non-sensing area; and a sensor electrode disposed in the sensing area and including sensor patterns. The sensing area may include a first area including at least one non-square boundary with a predetermined curvature and a second area not including the non-square boundary. In an exemplary embodiment of the present inventive concept, sensor patterns disposed in the first area and sensor patterns disposed in the second area among the sensor patterns may have different sizes from each other.
