Abstract: A display panel and an evaporation method for the display panel. The display panel includes: a first electrode, a second electrode and a light emitting structure layer positioned between the first electrode and the second electrode. The light emitting structure layer includes: a light emitting layer; an electron transport layer arranged on a side of the light emitting layer facing away from the first electrode, and including a plurality of doped layers that are stacked; an electron injection layer positioned on a side of the electron transport layer facing away from the light emitting layer. The electron transport layer has a reference plane positioned in the middle of the electron transport layer along the thickness direction of the display panel.

Abstract: Disclosed is a display panel, which solves the problem that water and oxygen easily intrude from the edge of the isolation layer in the prior art. The display panel includes an array substrate, including a display area and a frame area surrounding the display area; a protrusion located in the frame area, the protrusion comprising a first side wall on a side close to the display area and a second side wall on a side away from the display area, at least one of the first side wall and the second side wall comprising a concave area; and an isolation layer stacked on one side of the array substrate and the protrusion, the protrusion being located in an orthographic projection of the isolation layer on the array substrate.
