1. A display panel, comprising:
a display pixel unit located in a display region, the display pixel unit comprising a first transistor, the first transistor comprising a first channel and a second channel, the first channel and the second channel being connected by a conductive connection portion;
a dummy pixel unit located in a dummy region, the dummy region being at a side of the display region and being a non-light-emitting region;
a first signal line located in the dummy region, the first signal line being configured to supply a constant voltage; and
a first conductive block connected with the first signal line,
wherein the display pixel unit comprises a first display pixel unit, the first display pixel unit is a display pixel unit adjacent to the dummy pixel unit in a row direction, and in a plan view of the display panel, the first conductive block at least partially overlaps with the conductive connection portion of the first transistor of the first display pixel unit.
