Abstract
The present disclosure provides a display panel and a display apparatus. The display panel includes: a display substrate; a touch electrode layer on a light outgoing side of a display substrate and including at least one first electrode and at least one second electrode, which intersect with each other and are insulated from each other; an additional electrode layer in a layer different from the touch electrode layer and including at least one first additional electrode, wherein an orthographic projection of the at least one first additional electrode on the display substrate at least partially overlaps an orthographic projection of a corresponding first electrode on the display substrate; and an insulating layer between the additional electrode layer and the touch electrode layer; wherein the at least one first additional electrode is connected to the corresponding first electrode through at least one first via in the insulating layer.
