1. A display panel, comprising:
a base substrate comprising a display region, the display region comprising a first region, a second region surrounding the first region, and a transition region between the first region and the second region, a light transmittance of the first region being greater than that of the second region;
a plurality of first light-emitting elements arranged at the first region;
a plurality of second light-emitting elements, a plurality of first pixel circuitries and a plurality of second pixel circuitries arranged at the transition region, each first pixel circuitry being arranged between adjacent second pixel circuitries, an orthogonal projection of at least one second pixel circuitry onto the base substrate at least partially overlapping an orthogonal projection of at least one second light-emitting element onto the base substrate;
a plurality of first conductive lines each coupled between at least one first pixel circuitry and at least one first light-emitting element; and
a plurality of second conductive lines each coupled to at least one first pixel circuitry and extending along the at least one first pixel circuitry coupled to the plurality of second conductive lines to a side away from the at least one first light-emitting element;
wherein the at least one first pixel circuitry comprises a dummy electrode arranged at a side of the first conductive line away from the base substrate and electrically coupled to the first conductive line.
