Abstract
A touch sensor module according to an embodiment of the present invention includes a touch sensor layer including sensing electrodes and traces branching from the sensing electrodes, a flexible circuit board electrically connected to the traces at one end portion of a top surface of the touch sensor layer, a supporting structure commonly and partially covering the flexible circuit board and the touch sensor layer, and an adhesive layer formed on at least one surface of the touch sensor layer. The adhesive layer has a flexural rigidity in a range from 0.01 to 5 N·nm. Damages and delamination of electrodes and wirings included in the flexible circuit board and the touch sensor layer are prevented by the supporting structure.
