Claim 0:
1. A display panel, comprising:
a base;
a plurality of sub-pixels disposed on the base, each sub-pixel including a pixel circuit, the pixel circuit including a driving transistor and at least one first switching transistor, and the at least one first switching transistor being electrically connected to a control electrode of the driving transistor; and
a plurality of gate control lines disposed on the base, each pixel circuit being electrically connected to at least two gate control lines, wherein:
a first switching transistor includes an active layer, the active layer includes an active layer body and at least one extension portion, and the active layer body includes at least one channel portion and at least one conductive portion; and
an extension portion is electrically connected to a conductive portion of the active layer body, and at least a portion of an orthogonal projection of the extension portion on the base is overlapped with an orthogonal projection of a gate control line on the base, wherein:
the at least one extension portion includes at least one first extension portion;
the active layer body of the first switching transistor includes two channel portions and three conductive portions, and the three conductive portions and the two channel portions are electrically connected alternately in sequence;
the orthogonal projection of the gate control line on the base is overlapped with orthogonal projections of the two channel portions of the first switching transistor on the base; and
a first extension portion of the first switching transistor is electrically connected to a conductive portion located between the two channel portions of the first switching transistor, and at least a portion of an orthogonal projection of the first extension portion of the first switching transistor on the base is overlapped with the orthogonal projection of the gate control line on the base.
