Abstract: The touch control display panel comprises an array substrate and an alignment substrate arranged in alignment with the array substrate. The alignment substrate comprises a black matrix arranged on a first substrate. The black matrix protrudes from the first substrate, and the orthographic projection of a side of the black matrix away from the first substrate on the first substrate covers an orthographic projection of a side of the black matrix close to the first substrate on the first substrate. The first substrate is further provided with a plurality of touch control electrode groups formed using the black matrix as a mask plate. The present invention can effectively reduce the number of mask plates and the process steps as well as the production cost, which can further reduce the thickness of the touch control display panel and facilitates the manufacture of light and thin products.
