Abstract
The application provides a driver board and a display panel; the driver board comprises a substrate, a metal oxide semiconductor active layer, a gate layer, and a first protective layer; the gate layer is arranged on the side of the metal oxide semiconductor active layer away from the substrate, the first protective layer covers the gate layer, the material of the first protective layer is metal oxide semiconductor, and the oxygen content of the first protective layer is greater than the oxygen content of the metal oxide semiconductor active layer. The first protective layer in the driver board of the present application could block water vapor in the environment, so as to improve the transistor performance.
