1. A display panel, wherein, the display panel comprises:
a substrate; and
a plurality of subpixels, disposed on the substrate, each of the subpixels comprises:
a compensating transistor;
a drive transistor;
a storage capacitance; and
a first initialization signal line;
wherein, a first polar of the compensating transistor is connected with a second polar of the drive transistor, a second polar of the compensating transistor is connected with a gate of the drive transistor and a first polar plate of the storage capacitance, respectively;
a first active pattern of the compensating transistor comprises a first active section, a second active section and a third active section which are sequentially connected, the second active section extends along a first direction, and extension directions of the first active section and the third active section intersect with the first direction; and
the first initialization signal line extends along the first direction, and an overlapping area exist between an orthogonal projection of the first initialization signal line on the substrate and an orthogonal projection of the second active section on the substrate.
