Abstract
The present disclosure provides a touch display panel including an array substrate, a color filter substrate and a plurality of photo spacers. The array substrate includes pixel units, a drive circuit, touch leads, and a common electrode layer. The common electrode layer is divided into columns of self-capacitive electrodes. Each touch lead is disposed parallel to and connected with one of the columns through at least two first via holes. An interval between adjacent first via holes is greater than or equal to twice the side length of one pixel unit. The first via holes connected with one touch lead are aligned staggered to those connected with an adjacent touch lead and none of the photo spacers overlap the first via holes in the direction perpendicular to the array substrate.
