Abstract: In a touch display panel and a touch display device, a shielding pattern including the common electrode (COM) used as the touch electrode (TE) is disposed between a touch line (TL) and a data line (DL), and the touch line (TL) and the data line (DL) are arranged so as not to overlap each other in a boundary area between shielding patterns. The parasitic capacitance between the touch line (TL) and the data line (DL) can be reduced to improve the performance of touch sensing. In addition, the arrangement of the touch lines (TL) and data lines (DL) in the boundary area between shielding patterns is repeated at regular intervals to prevent an image abnormality.

Abstract: The present disclosure 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.
