1. A display panel comprising:
a substrate; and
an array layer disposed on one side of the substrate, the array layer including a first-type thin film transistor and a second-type thin film transistor;
wherein a first active layer of the first-type thin film transistor and a second active layer of the second-type thin film transistor are both metal oxide active layers, and a sub-threshold swing value of the first-type thin film transistor is greater than a sub-threshold swing value of the second-type thin film transistor.
