Abstract
A touch sensor according to an embodiment of the present disclosure may include a substrate layer, sensing electrodes that are formed on the substrate layer, and a black matrix that is formed on the same layer as the sensing electrodes or on a lower portion of the sensing electrodes. It may be possible to prevent excessive thermal damage to the sensing electrode which may occur during forming the black matrix after the sensing electrode is formed.
