1. A display panel, comprising:
a base substrate; and
a plurality of pixel circuits arranged on the base substrate, wherein at least one of the pixel circuits comprises a drive transistor and a first switch transistor;
wherein the display panel further comprises:
an active layer arranged on the base substrate, wherein the active layer comprises a first active portion and a second active portion, the first active portion is configured to form a channel portion of the drive transistor, and the second active portion is configured to form a second electrode connection portion of the first switch transistor; and
a first conductive layer arranged on a side of the active layer away from the base substrate,
wherein the first conductive layer comprises a first conductive portion, a portion of the first conductive portion is configured to form a gate electrode of the drive transistor, and another portion of the first conductive portion is electrically connected to the second active portion, and
a channel length of the channel portion of the drive transistor is greater than a channel width of the channel portion of the drive transistor.
