Claim Text:
1. A touch display panel comprising: a touch sensor having a plurality of first electrodes for receiving a touch driving signal and a plurality of second electrodes for generating a sense signal according to the touch driving signal; a first substrate; a second substrate disposed opposite to and above the first substrate, wherein the plurality of second electrodes are disposed on the second substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a transmitting circuit for transmitting the touch driving signal to the plurality of first electrodes, wherein the transmitting circuit and the plurality of first electrodes are disposed between the first substrate and the liquid crystal layer or between the second substrate and the liquid crystal layer; and a grounding electrode configured to electrically connect to a ground and disposed above and at least partially overlapped with the transmitting circuit, and configured to shield an electrical field generated by the transmitting circuit when the transmitting circuit is transmitting the touch driving signal.
