Abstract
The touch display panel comprises an array substrate, a color film substrate a touch electrode layer located at a side of the color film substrate away from the array substrate, and a transparent electrically conductive layer between the color film substrate and the touch electrode layer and insulated from the touch electrode layer. The transparent electrically conductive layer comprises a first area and a second area, a thickness of the transparent electrically conductive layer in the first area is greater than a thickness of the transparent electrically conductive layer in the second area, the transparent electrically conductive layer is suitable for being electrically connected to ground. A projection area of the touch electrode layer on the color film substrate overlaps with a projection area of the transparent electrically conductive layer located in the second area on the color film substrate.
