Abstract
An array substrate and a display panel. The array substrate includes a thin film transistor array layer including a driving transistor, a switching transistor, and a capacitor. The driving transistor includes a first active layer, a first gate insulating layer, a first gate, and an insulating dielectric layer sequentially stacked. The switching transistor includes a second active layer, a second gate insulating layer, and a second gate sequentially stacked. The insulating dielectric layer and the second gate insulating layer are located at a same layer. A thickness of the first gate insulating layer is greater than a thickness of the second gate insulating layer. The capacitor includes a first electrode plate and a second electrode plate. The first electrode plate and the first gate are disposed on same layer, and the second electrode plate and the second gate are disposed on same layer.
