Display panel and display device

A display device, comprising a display panel,

• wherein the display panel comprises:
• a substrate;
• a pixel circuit layer, arranged on a side of the substrate and comprising at least one pixel circuit, wherein the pixel circuit comprises an initialization transistor, an active layer of the initialization transistor comprises a channel region, a first electrode region, and a second electrode region;
• the first electrode region and the second electrode region are disposed on two sides of the channel region respectively;
• at least one light-emitting element, arranged on a side of the pixel circuit layer away from the substrate and electrically connected to the pixel circuit, wherein the light-emitting element comprises a first electrode, a light-emitting material layer, and a second electrode disposed in a laminated manner;
• at least one auxiliary electrode, arranged on the side of the pixel circuit layer away from the substrate and electrically connected to the second electrode, wherein the auxiliary electrode is electrically connected to the second electrode region of the active layer of the initialization transistor through a via hole.
