Display panel and display device

A display device, comprising:

• a power component, and a display panel;
• wherein
• the power component is electrically connected to the display panel, and is configured to supply power to the display panel;
• and
• the display panel comprises:
• a substrate;
• an auxiliary electrode on a side of the substrate;
• an insulating layer on a side, distal from the substrate, of the auxiliary electrode and a first via running through the insulating layer, the first via exposing the auxiliary electrode and being in an undercut shape;
• an anode layer on a side, distal from the substrate, of the insulating layer;
• a light emitting layer on a side, distal from the substrate, of the anode layer, the light emitting layer being broken at an opening in a side, distal from the substrate, of the first via into a first part and a second part, the first part being outside the first via and on the side, distal from the substrate, of the insulating layer, and the second part being inside the first via and on a side, proximal to the substrate, of the insulating layer;
• and
• a cathode layer on a side, distal from the substrate, of the light emitting layer, the cathode layer being coupled with the auxiliary electrode along a side wall of the first part of the light emitting layer, and the coupled part of the cathode layer and the auxiliary electrode being on a side, proximal to the substrate, of the anode layer.
