Display panel and display device

A display panel having a transparent display region, comprising:

• a plurality of sub-pixels disposed in the transparent display region,
• wherein, in two adjacent sub-pixels among at least a part of a plurality of two adjacent sub-pixels of the plurality of sub-pixels, a bottom electrode of a first sub-pixel of the two adjacent sub-pixels has a first shape type, and a bottom electrode of a second sub-pixel of the two adjacent sub-pixels has a second shape type, the second shape type is the same as a shape of a light-emitting region of the second sub-pixel of the two adjacent sub-pixels,
• wherein the first shape type comprises a circle or an ellipse, and the plurality of sub-pixels are arranged in lines,
• wherein the sub-pixels in each line of the plurality of sub-pixels are divided to form a plurality of first repeating units, each first repeating unit among the plurality of first repeating units comprises three sub-pixels of the plurality of sub-pixels, and
• wherein, in the first repeating unit of at least a part of the plurality of first repeating units, bottom electrodes of two adjacent sub-pixels have the first shape type, and a bottom electrode of a third sub-pixel has the second shape type.
