Display panel, method for manufacturing same, and display device

A method for manufacturing a display panel, comprising:

• wherein
• the plurality of first sub-pixels comprise at least one first target sub-pixel and at least one second target sub-pixel, wherein the planarization layer of the first target sub-pixel is provided with a protruding structure, and a maximum distance between a side, away from the base substrate, of the planarization layer of the second target sub-pixel and a side, close to the base substrate, of the planarization layer of the second target sub-pixel is smaller than a maximum distance between a side, away from the base substrate, of the planarization layer of the first target sub-pixel and a side, close to the base substrate, of the planarization layer of the first target sub-pixel;
• wherein for the first target sub-pixel, an orthographic projection of a portion, in contact with both the electrode pattern and the electrode layer, of the light-emitting pattern of the first target sub-pixel on the base substrate covers an orthographic projection of the protruding structure in the planarization layer of the first target sub-pixel on the base substrate;
• and
• wherein each of the sub-pixels further comprises a pixel defining layer disposed on a side, away from the base substrate, of the electrode pattern, the pixel defining layer being provided with an opening, at least a portion of the light-emitting pattern of the sub-pixel being disposed in the opening;
• wherein
• a slope angle of the opening in the pixel defining layer of each first target sub-pixel is smaller than a slope angle of the opening in the pixel defining layer of any second target sub-pixel;
• wherein the slope angle of the opening in the pixel defining layer is an angle between a side face of the opening in the pixel defining layer and a side, close to the base substrate, of the pixel defining layer.
