Abstract: PURPOSE: A thin film transistor and a manufacturing method thereof are provided to reduce a leakage current by comprising a channel layer of a multi-layered film with different crystal grains. CONSTITUTION: A thin film transistor includes a gate, a gate insulation layer(130), a channel layer(140), a source, and a drain. The channel layer comprises a first oxide semiconductor layer and a second oxide semiconductor layer. The source and drain are contacted with both sides of the channel layer. The crystal grain of a first oxide semiconductor layer is relatively larger than the crystal grain of a second oxide semiconductor layer.
