Abstract
A touch sensor comprises a touch sensor layer having an electrode pad portion formed in a bezel area, and a polarizing layer coupled to the touch sensor layer while opening an area of the electrode pad portion and having a side surface of an area of the electrode pad portion defining an altered surface and a side surface excluding the area of the electrode pad portion defining a straight line surface. The altered surface and the straight line surface have a cross-sectional inclination angle of 30° or less in a lateral direction with respect to a vertical direction.
