1. A display panel, having a plurality of sub-pixels and comprising:
a base substrate;
a transistor array layer disposed on the base substrate and comprising anode adaptor portions each located in a respective one of the plurality of sub-pixels;
a first planarization layer, disposed on a side of the transistor array layer facing away from the base substrate; and
a first electrode layer, disposed on a side of the first planarization layer facing away from the base substrate and comprising anodes each located in the respective one of the plurality of sub-pixels; wherein
each anode comprises a main part and a via hole part electrically connected to each other;
in the respective one of the plurality of sub-pixels: the via hole part is electrically connected with the anode adaptor portion through a first via hole; and the first via hole runs through the first planarization layer;
wherein
the plurality of sub-pixels comprise first color sub-pixels and second color sub-pixels adjacent to the first color sub-pixels in a first direction; and orthographical projections of first via holes in the first color sub-pixels on the base substrate are located between orthographical projections of main parts in the first color sub-pixels on the base substrate and orthographical projections of main parts in the second color sub-pixels on the base substrate;
for the first color sub-pixels and the second color sub-pixels adjacent to the first color pixels in the first direction, sides of orthographical projections of anodes in the second color sub-pixels on the base substrate facing to orthographical projections of anodes in the first color sub-pixels on the base substrate have first notches; and the first notches are convex toward centers of the main parts of the second color sub-pixels;
wherein the display panel comprises a plurality of repeating units, and each repeating unit comprises at least one of the first color sub-pixels and at least one of the second color sub-pixels; and
every two adjacent repeating units have at least two of the first notches and two of the first via holes; and in the first direction, the at least two of the first notches and the at least two of the first via holes of at least two adjacent repeating units are arranged on a same straight line.
