Abstract
A display panel and a manufacturing method thereof are disclosed. The display panel includes an oxide active part, a gate electrode, conduction protective parts, a passivation part, and a source-drain electrode. The oxide active part includes a semiconductor part and conductor parts, and the passivation part is disposed on the gate electrode and the conduction protective parts. The source-drain electrode is disposed on one side of the conduction protective parts and the oxide active part and is connected to the conductor parts. Therefore, a reaction between the passive part and the conductor parts is less likely to occur, thereby ensuring a performance of the display panel.
