A driving circuit includes a first transistor, a second transistor and a third transistor. The first transistor has a first terminal connected to a first voltage level, a second terminal, and a third terminal. The second transistor has a first terminal connected to the second terminal of the first transistor, a second terminal connected to a second voltage level, and a third terminal connected to the third terminal of the first transistor. The third transistor has a first terminal connected to the first terminal of the second transistor. The first transistor and the second transistor are low temperature poly-silicon transistors, and the third transistor is an oxide semiconductor transistor.
