Abstract:
A thin film transistor including a gate, a channel, a stopper layer, a source and a drain is provided. The channel and the gate are overlapped. The stopper layer covers a portion of the channel and has a ring-shape hole exposing two opposite connecting portions of the channel. A portion of the stopper layer is disposed between the source and the channel and between the drain and the channel. The source and the drain are filled in the ring-shape hole of the stopper layer and electrically connected to the connecting portions of the channel. Moreover, a pixel structure including the thin film transistor is provided.
