Abstract: A touch sensor integrated display device includes a plurality of common electrode blocks that defines a plurality of touch driving channels and a plurality of touch sensing channels. The touch driving channel is formed of a group of common electrode blocks electrically linked via a touch signal line placed under the layer of the common electrode blocks. The source/drain of the circuit TFTs provided in the non-display area is formed of the same metal layer of the touch signal line. The source/drain of the pixel TFTs provided in the display area is formed of a metal layer different from the metal layer of the touch signal line.
