Display panel and display device

A display panel, comprising:

• a base substrate comprising a display region and a peripheral region;
• a plurality of sub-pixels arranged in the display region, wherein the sub-pixels comprise a first electrode, a second electrode, and a functional layer located between the first electrode and the second electrode;
• a first electrode layer arranged on the base substrate, wherein the first electrode of the plurality of sub-pixels is located in the first electrode layer;
• a pixel defining layer arranged on a side of the first electrode layer away from the base substrate, wherein the pixel defining layer comprises a pixel defining layer body having a first part and a second part, the first part is located in the display region and comprises an opening corresponding to the plurality of sub-pixels, and an orthographic projection of the opening on the base substrate falls within an orthographic projection of the first electrode of the plurality of sub-pixels on the base substrate, the second part is located in the peripheral region, and the second part and the first part are formed as an integral structure;
• and
• a spacer layer arranged on a side of the pixel defining layer away from the base substrate, wherein the spacer layer comprises a first spacer repetitive unit located in the display region and a second spacer repetitive unit located in the peripheral region;
• wherein an orthographic projection of the second spacer repetitive unit on the base substrate falls within an orthographic projection of the second part of the pixel defining layer on the base substrate and is located on a side, facing the display region, of a boundary, which is away from the display region, of the second part, and the orthographic projection of the second spacer repetitive unit on the base substrate does not overlap the orthographic projection of the first electrode of the plurality of sub-pixels on the base substrate.
