Abstract
A touch sensor according to an embodiment of the present invention includes a substrate layer, and sensing electrodes which are disposed on the substrate layer, and have etching regions formed therein in a periodically repeated manner and respectively having a width of 5 to 15 μm. Through the etching regions, transmittance may be improved and optical interference with an image display device may be reduced. The present invention also provides a window stack structure and an image display device including the touch sensor.
