An emission driver includes a latch circuit and a buffer circuit. The latch circuit receives a first signal, a second signal, and a first clock signal. The latch circuit includes a first output terminal and a second output terminal. The first output terminal of the latch circuit outputs a third signal according to the first clock signal. The second output terminal of the latch circuit outputs a fourth signal in reverse to the third signal according to the first clock signal. The buffer circuit includes a first input terminal, a second input terminal and a third output terminal. The first input terminal of the buffer circuit receives the third signal. The second input terminal of the buffer circuit receives the fourth signal. The third output terminal of the buffer circuit outputs an emission signal according to the third signal and the fourth signal.
