1. A display panel, comprising:
a base substrate having a display area and a non-display area surrounding the display area, the display area comprising a first display sub-area and a second display sub-area;
a plurality of first light emitting elements formed on the base substrate and located in the first display sub-area, wherein each of the first light emitting elements comprises a first pixel electrode, a gap exists between adjacent first pixel electrodes, and the gaps around the first pixel electrodes in at least two of the first light emitting elements with the same light emitting color have different patterns; and
a plurality of first pixel circuits, formed on the base substrate and located in at least one of the second display sub-area and the non-display area, wherein the first pixel circuits are electrically connected to the first pixel electrodes via a conductive wire, wherein:
the first pixel electrode comprises a first main electrode portion and a first connection portion that are located in the same layer and connected to each other, and at least a part of the first connection portion is electrically connected to the conductive wire through a first via structure located in the first display sub-area; and
a respective gap between the first main electrode portion and the first via structure connected thereto through the first connection portion is a first gap, and the first gaps in at least two of the first light emitting elements with the same light emitting color are different, wherein the first gap has a value from 0 to 10 μm.
