1. A display panel, comprising:
a first display area and a second display area;
a substrate;
a light-emitting layer located on a side of the substrate and comprising a plurality of first pixel repeating units disposed in the first display area, wherein one of the first pixel repeating units comprises a plurality of first sub-pixels;
a plurality of second pixel repeating units disposed in the second display area, wherein one of the second pixel repeating units comprises a plurality of second sub-pixels, number of the second sub-pixels in the second pixel repeating unit is same as number of the first sub-pixels in the first pixel repeating unit, and a distance between any two of the second sub-pixels in the second pixel repeating unit is less than a distance between any two of the first sub-pixels in the first pixel repeating unit; and
a cathode inhibition layer disposed on a side of the light-emitting layer away from the substrate and comprising a plurality of cathode inhibition blocks located in the second display area and disposed between adjacent ones of the second pixel repeating units; and
a cathode layer disposed on the light-emitting layer and located on the side of the light-emitting layer away from the substrate, wherein an opening is located in the cathode layer corresponding to a position of each of the cathode inhibition blocks.
