Abstract
A display panel includes at least one driving circuit and at least one pixel circuit. A driving circuit of the at least one driving circuit provides a driving signal for a pixel circuit of the at least one pixel circuit. The driving circuit includes N-level shift registers cascaded with each other. N is greater than or equal to two. The pixel circuit provides a display signal for a display unit of the display panel. A shift register of the N-level shift registers includes at least one first transistor. The at least one first transistor includes at least one first active layer, and an active layer with a largest area among the at least one first active layer is a first preset active layer. The pixel circuit includes at least one second transistor. The at least one second transistor includes at least one second active layer.
