Display device and manufacturing method thereof

摘要

A display device and a manufacturing method thereof with improved performance and low manufacturing complexity are provided. One inventive aspect includes: a first control electrode, a semiconductor layer, an etch stop layer, a first input electrode and a first output electrode, a third control electrode, a passivation layer and a pixel electrode. The third control electrode is formed on the etch stop layer. The passivation layer is formed on the first electrode, the first output electrode and the third control electrode. The pixel electrode is formed on the passivation layer and connects to the first output electrode.
