Display panel, method for manufacturing the same, and display device

A method for manufacturing a display panel, comprising:

• providing a back plate, the back plate comprising a driving circuit, an anode layer, and a pixel defining layer;
• forming a conductive layer on the pixel defining layer of the back plate;
• forming an eaves blocking layer on the conductive layer, wherein the pixel defining layer, the conductive layer, and the eaves blocking layer are stacked to form an overhang structure;
• forming at least one groove structure in the eaves blocking layer;
• coating a photoresist material over an entire surface to form a photoresist layer;
• forming a plurality of pixel openings between adjacent overhang structures;
• depositing a light-emitting material on the anode layer to form a light-emitting layer, with the light-emitting material partially falling into the at least one groove structure;
• depositing a cathode material on the light-emitting layer to form a cathode layer, wherein the cathode layer is connected together via the conductive layer, and wherein the anode layer, the light-emitting layer, and the cathode layer are stacked to form a light-emitting element;
• coating a first encapsulating material above the overhang structures and the cathode layer to form a first inorganic encapsulation layer, with the first encapsulating material partially falling into the at least one groove structure and covering the light-emitting material;
• removing the photoresist layer;
• repeatedly performing the above operations of forming the light-emitting element and encapsulating the first inorganic encapsulation layer to achieve the formation of all light-emitting elements and the encapsulation using the first inorganic encapsulation layer;
• and
• performing a full-surface encapsulation above the first inorganic encapsulation layer to obtain an encapsulated display panel.

A display device, comprising a display panel, the display panel comprising:

• a substrate;
• a plurality of overhang structures, arranged on the substrate and spaced apart from each other, wherein adjacent overhang structures are arranged in an encircling manner to form a plurality of pixel openings;
• a plurality of light-emitting elements, arranged in the plurality of pixel openings in one-to-one correspondence a first inorganic encapsulation layer, arranged on a side of the overhang structure facing away from the substrate;
• and
• an organic encapsulation layer, arranged on a side of the first inorganic encapsulation layer facing away from the plurality of overhang structures;
• light-emitting element
• wherein each of the plurality of overhang structures comprises a pixel defining layer, a conductive layer, and an eaves blocking layer that are stacked in sequence;
• wherein the eaves blocking layer comprises at least one groove structure in a side facing away from the conductive layer;
• wherein each of the at least one groove structure is sequentially filled with a light-emitting material and a first inorganic encapsulating material.
