Abstract
The present application discloses a touch control display panel including a base substrate; an auxiliary electrode layer on the base substrate; an insulating layer on a side of the auxiliary electrode layer distal to the base substrate; and a first touch electrode layer and a second touch electrode layer on a side of the insulating layer distal to the auxiliary electrode layer. The first touch electrode layer and the auxiliary electrode layer are electrically connected in parallel; and the second touch electrode layer is insulated from the first touch electrode layer and the auxiliary electrode layer.
