Abstract
The present invention relates to a film touch sensor comprising a separation layer; a first protection layer that is formed on the separation layer; a touch detection layer that is formed on the first protection layer; a second protection layer that is formed on the touch detection layer; and an optical compensation layer that is formed between the first protection layer and the touch detection layer, or between the touch detection layer and the second protection layer, and that compensates for a transmittance difference between the patterned region in which a transparent electrode pattern forming the touch detection layer is formed, and a non-patterned region in which the transparent electrode pattern is not formed.
