Display panel, manufacturing method thereof, and electronic device

An electronic device, comprising a display panel, wherein the display panel comprises:

• a base substrate;
• an anode metal layer disposed on one surface of the base substrate and comprising a plurality of anodes;
• a pixel definition layer disposed on a surface of the anode metal layer facing away from the base substrate;
• wherein the pixel definition layer comprises:
• a plurality of pixel openings corresponding to the anodes, at least part of an anode of the plurality of anodes being exposed through a pixel opening corresponding to the anode;
• a plurality of first protrusions disposed on a surface of the pixel definition layer facing away from the base substrate, each of the plurality of first protrusions being located between two adjacent pixel openings in a first direction, the first direction being parallel to a plane where the base substrate is located;
• wherein each of the plurality of first protrusions has a first orthogonal projection on the plane where the base substrate is located, and each of the plurality of pixel openings has a second orthogonal projection on the plane;
• in the first direction, the first orthogonal projection is parallel to two adjacent second orthogonal projections.

A manufacturing method of a display panel, comprising:

• providing a base substrate;
• forming a patterned anode metal layer on a surface of the base substrate, the anode metal layer comprising a plurality of anodes;
• forming an initial pixel definition layer on the surface of the base substrate on which the plurality of anodes are formed;
• forming a pixel definition layer with a desired pattern structure in the initial pixel definition layer by using a half-tone mask,
• wherein the pixel definition layer comprises:
• a plurality of pixel openings in one-to-one correspondence with the anodes, wherein at least part of an anode of the plurality of anodes is exposed through a pixel opening corresponding to the anode;
• a plurality of first protrusions disposed on a surface of the pixel definition layer facing away from the base substrate, wherein each of the plurality of first protrusions is located between two adjacent pixel openings in a first direction, the first direction is parallel to a plane where the base substrate is located;
• wherein each of the first protrusions has a first orthogonal projection on the plane where the base substrate is located, and each of the pixel openings has a second orthogonal projection on the plane;
• in the first direction, the first orthogonal projection is parallel to two adjacent second orthogonal projections.
