Abstract
A film touch sensor includes a separation layer, a first protection layer on the separation layer, and an electrode pattern layer on the first protection layer. An alkoxy group having 1 to 5 carbon atoms from the separation layer, and at least one substituent group of a hydroxyl group, a carboxyl group or an amide group from the first protection layer are reacted with each other to form a chemical bond between the separation layer and the first protection layer. Thus, electrode damages and cracks are prevented during a detaching process from a carrier substrate to improve flexibility and durability of the film touch sensor.
