Abstract: A touch sensor module includes a touch sensor layer including sensing electrodes and traces extending from the sensing electrodes, an optical layer on the touch sensor layer to cover the sensing electrodes, a circuit connection structure spaced apart from the optical layer and electrically connected to the traces on an end portion of the touch senor layer, and a colored resin pattern filling a gap between the optical layer and the circuit connection structure. An optical disturbance at the gap is prevented by the colored resin pattern.
