Display panel, display device, and method of preparing the same

A display panel, comprising:

• an array substrate;
• a first electrode layer located on a side of the array substrate and comprising a pixel electrode;
• a pixel definition layer located on a side of the first electrode layer away from the array substrate and comprising an isolation portion and a pixel opening surrounded by the isolation portion;
• a second electrode layer located on a side of the pixel definition layer away from the array substrate and comprising a second electrode and an opening;
• wherein the second electrode comprises a body portion and an edge portion arranged as extending from the body portion and toward the opening, the body portion contacts the pixel definition layer, the edge portion contacts the array substrate or the pixel definition layer, and an adhesion force between the edge portion and the array substrate or the pixel definition layer is greater than an adhesion force between the body portion and the pixel definition layer.

A display panel, comprising:

• an array substrate, wherein the array substrate comprises a first blocking layer, and the first blocking layer comprises a first through hole;
• a first electrode layer located on a side of the array substrate, wherein the first electrode layer comprises a pixel electrode;
• a pixel definition layer located on a side of the first electrode layer away from the array substrate, wherein the pixel definition layer comprises an isolation portion and a pixel opening surrounded by the isolation portion;
• a second electrode layer located on a side of the pixel definition layer away from the array substrate, wherein the second electrode layer comprises a second electrode and an opening, the second electrode comprises a body portion and an edge portion arranged as extending from the body portion and toward the opening;
• wherein an orthographic projection of the first through hole in a thickness direction of the display panel overlaps an orthographic projection of the opening in the thickness direction of the display panel, a distance between the edge portion and the first blocking layer in the thickness direction of the display panel is less than a distance between the body portion and the first blocking layer in the thickness direction of the display panel.
