Abstract
A touch sensor includes a base layer, sensing electrodes arranged on the base layer, a bridge electrode and a connecting portion. The sensing electrode layer includes first sensing electrodes arranged along a first direction parallel to a top surface of the base layer, and second sensing electrodes arranged along a second direction parallel to the top surface of the base layer. The bridge electrode is disposed on the sensing electrodes to electrically connect the first sensing electrodes neighboring in the first direction to each other. The bridge electrode includes an extension portion and expanded portions formed both ends of the extension portion. The expanded portion has a width greater than that of the extension portion. The connecting portion electrically connects the second sensing electrodes neighboring in the second direction and includes at least one etched region.
