Abstract
Embodiments disclosed herein relate to a touch display panel and a touch display device. By arranging a shielding structure, which is connected to a touch electrode in a region where a touch line and a data line overlap each other or is applied with a shielding signal corresponding to a touch driving signal from an outside circuit, between the touch line and the data line, it is possible to prevent direct capacitance from being formed between the touch line and the data line, and to prevent the capacitance formed due to the data line from causing noise on a touch sensing signal. In addition, by arranging a touch load reduction layer between the shielding structure and the touch line, it is also possible to reduce the capacitance between the touch line and the data line arranged in the horizontal direction, thereby improving touch sensing performance.
