Abstract: The invention relates to touch display device and display panel. Provided are a touch display device and a display panel able to improve touch sensing performance by reducing crosstalk occurring between data lines and touch lines. A shield pattern is disposed in an area in which the touch lines overlap the data lines. A shield signal is applied to the shield pattern through shield lines in an area in which the shield pattern does not overlap the touch lines or the data lines. Direct capacitance is not formed between the touch lines and the data lines.

Abstract: In a touch display panel (110) and a touch display device (100), a shielding pattern (SPTN) is arranged between a data link line (DLL) and a touch link line (TLL) in a non-active area (N/A; L/A) of the touch display panel, and a signal corresponding to the touch driving signal (TDS) is applied to the shielding pattern (SPTN). Parasitic capacitance (Cp) between the data link line (DLL) and the touch link line (TLL) is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line (DLL). Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.
