Display panel

A display panel, comprising a base substrate, a plurality of pixel units on the base substrate, wherein each of the plurality of the pixel units comprises a plurality of light-emitting units emitting light in different colors;

• each of the plurality of light-emitting unit comprises a first electrode, an organic functional layer and a second electrode stacked sequentially along a direction away from the base substrate;
• and
• among the plurality of light-emitting units emitting light in different colors in each pixel unit, the second electrode of the light-emitting unit emitting light with a shortest wavelength has a smallest thickness along a direction perpendicular to the base substrate,
• each of the plurality of light-emitting units comprises a first auxiliary structure on a side of the organic functional layer proximal to the second electrode layer,
• an adsorption force of the first auxiliary structure of the light-emitting unit emitting light with the shortest wavelength on a material of the second electrode layer is the smallest,
• the first auxiliary structure comprises a first material and/or a second material, the first material is a nucleation inhibition material for the material of the second electrode layer, and the second material is a nucleation promoting material for the material of the second electrode layer.
