Abstract
Provided are an inverter circuit structure, a gate driving circuit and a display panel. The inverter circuit structure includes a PMOS transistor and an NMOS transistor, and further includes a first active layer, a gate layer, a second active layer, a first insulating layer between the gate layer and the first active layer, and a second insulating layer between the gate layer and the second active layer. An orthographic projection of the gate on the first active layer is a first region, and a portion of the first active layer in the first region has substantially a same thickness. An orthographic projection of the gate on the second active layer is a second region, and a portion of the second active layer in the second region has substantially a same thickness.
