Abstract
A display panel includes a base, a plurality of sub-pixels and a plurality of gate control lines that are disposed on the base. Each sub-pixel includes a pixel circuit. The pixel circuit includes a driving transistor and at least one first switching transistor electrically connected to a control electrode of the driving transistor. Each pixel circuit is electrically connected to at least two gate control lines. 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. An extension portion is electrically connected to a conductive portion of the active layer body. 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.
