Display panel, manufacturing method therefor, and display device

A display panel, comprising:

• a substrate;
• light-emitting devices;
• a pixel definition layer, wherein the light emitting devices and the pixel definition layer are located at a side of the substrate, wherein the pixel definition layer comprises:
• apertures, wherein the apertures comprise first apertures provided with the light-emitting devices and a second aperture;
• and
• bank portions;
• and
• a first spacer structure provided in the second aperture;
• wherein along a direction perpendicular to a plane of the substrate, one bank portion of the bank portions comprises a first part, a distance from a surface of the first spacer structure away from the substrate towards the substrate is d1, and a distance from a surface of the first part away from the substrate towards the substrate is d2, where d1>d2,
• wherein the first spacer structure comprises a side surface and a bottom surface located at a side of the substrate, and an angle a formed between the side surface and the bottom surface is an acute angle;
• and
• wherein the display panel further comprising a support post located at a side of the first part away from the substrate, wherein the support post comprises a first sidewall and a first bottom surface, wherein the first bottom surface is a surface of the support post close to the substrate;
• and an angle between the first sidewall and the first bottom surface is β, wherein β<α.
