Abrégé

Provided are a display panel (100) and an electronic device. The display panel comprises a pixel driving circuit (202) and a plurality of cascaded gate driving circuits (102) loaded with a constant voltage signal, wherein each gate driving circuit (102) outputs a gate signal of the present stage to a corresponding pixel driving circuit (202) at least on the basis of the constant voltage signal, the absolute value of the voltage value of the constant voltage signal is within a first voltage interval, and the rate of change of the charge at a control end of a driving unit (2021) in the pixel driving circuit (202) is relatively small when the absolute value changes within the first voltage interval.
