1. A display panel, comprising a first display area and a second display area, the first display area comprising a transparent display area and a transition display area located between the transparent display area and the second display area, light transmittance of the transparent display area being greater than light transmittance of the second display area, the display panel comprising:
a light-emitting element layer comprising a first pixel structure arranged in the first display area, the first pixel structure comprising a plurality of first sub-pixels, and each of first sub-pixels comprising a first electrode;
a device layer stacked on the light-emitting element layer and comprising a plurality of first driving transistors located in the transition display area, each of the first driving transistors configured to drive one or more first sub-pixels emitting a same color, and each of the first driving transistors comprising a first gate electrode;
wherein the light-emitting element layer further comprises a second pixel structure arranged in the second display area, the second pixel structure comprises a plurality of second sub-pixels, each of the second sub-pixels comprises a second electrode, the device layer further comprises a plurality of second driving transistors located in the second display area and configured to drive the second sub-pixels, each of the second driving transistors comprise a second gate electrode, and in the stacking direction, an orthographic projection of a second gate electrode of one of the second driving transistors does not overlap an orthographic projection of a second electrode of a second sub-pixel emitting a color different from another second sub-pixel driven by the second driving transistor.
