Thin film transistor array substrate and liquid crystal panel

The invention discloses a thin film transistor array substrate and a liquid crystal panel. The thin film transistor array substrate comprises a substrate, a silicon thin film transistor, a semiconductor oxide transistor and a capacitor, wherein the silicon thin film transistor, the semiconductor oxide transistor and the capacitor are formed on the substrate. The silicon thin film transistor and the semiconductor oxide transistor are provided with an identical top gate structure, so that manufacture procedures of the silicon thin film transistor and the semiconductor oxide transistor can be compatible, use times of a photoresist mask plate are reduced, and the production cost of the thin film transistor array substrate is reduced. Moreover, the capacitor and the silicon thin film transistor or the semiconductor oxide transistor are overlapped, and thus the aperture ratio of bottom emitting organic light emitting diode (OLED) can be greatly increased.
