1. A touch display device comprising:
a display panel including:
a substrate having thereon a plurality of subpixels, and
an encapsulation layer disposed on the substrate,
a touch screen panel disposed on the encapsulation layer, the touch screen panel including:
a plurality of touch driving electrodes configured to receive touch driving signals through a plurality of touch driving lines,
a plurality of touch sensing electrodes, in operation, forming capacitances with the plurality of touch driving electrodes, the plurality of touch sensing electrodes configured to supply touch sensing signals through a plurality of touch sensing lines; and
a bridge line electrically connecting to at least two of the plurality of touch driving electrodes,
wherein the plurality of touch driving electrodes and the plurality of touch sensing electrodes are formed in a mesh-type shape having openings,
wherein the plurality of touch driving lines is disposed for a corresponding touch driving electrode of the plurality of touch driving electrodes,
wherein remaining touch driving lines of the plurality of touch driving lines except for a touch driving line electrically connected to the corresponding touch driving electrode are each shifted by a same distance in a direction different from a direction of their main extent within an area of the corresponding touch driving electrode, and
wherein the bridge line overlaps with at least one of the plurality of touch sensing electrodes.
