Display panel and display device

A display panel comprising a display area, wherein the display panel further comprises:

• a base substrate;
• a third conductive layer, disposed at a side of the base substrate and comprising a first conductive part positioned in the display area;
• a pixel electrode layer, disposed at a side of the third conductive layer away from the base substrate;
• and
• a common electrode layer, disposed at a side of the pixel electrode layer away from the base substrate, wherein the common electrode layer comprises at least one through-hole contacting part in the display area, and the through-hole contacting part is connected to the first conductive part via a first through hole,
• wherein the display panel further comprises a pixel driving circuit, wherein the pixel driving circuit comprises a driving transistor, and a first electrode of the driving electrode is connected to a first electrode of a light emitting unit,
• the pixel electrode layer comprises a pixel electrode part configured to form the first electrode of the light emitting unit,
• wherein the display panel further comprises:
• a second conductive layer, disposed between the base substrate and the third conductive layer, wherein the second conductive layer comprises a second conductive part connected to the first electrode of the driving transistor,
• wherein a first opening is formed on the first conductive part, and an orthographic projection of the first opening on the base substrate is at least partly overlapped with an orthographic projection of the second conductive part on the base substrate, the pixel electrode part is connected to the second conductive part via a second through hole, and an orthographic projection of the second through hole on the base substrate is positioned within the orthographic projection of the first opening on the base substrate.
