Embedded touch display panel

The invention discloses an embedded touch display panel. The display panel has a display region and a non display region; pixel regions are formed in regions surrounded by gate lines and data lines which are mutually intersected in the display region; each pixel region has a pixel structure; each pixel structure comprises a gate, a source and a drain of a thin film transistor, a semiconductor layer, a pixel electrode and a sub common electrode; each common electrode comprises multiple touch electrodes; each touch electrode corresponds to multiple pixel electrodes; each pixel electrode corresponds to one sub common electrode; the sub common electrodes serve as a part of the touch electrodes; each touch electrode is electrically connected with at least one sensing line; the data lines and the sub common electrodes are all formed on a same insulation layer; a metal connection structure is electrically connected with the sub common electrodes in the two adjacent pixel structures; and the metal connection structur
