A push-pull buffer amplifier and a source driver are provided. In the buffer amplifier, the N-type and the P-type comparators compare an input signal and an output signal. The input terminals of the first and the second inverters are coupled to the first output terminals of the N-type and the P-type comparators, respectively. The first and the fourth transistors are controlled by the second output terminal of the N-type comparator and the output terminal of the second inverter, respectively, so that the first voltage line charges/discharges an output load. The second and the third transistors are controlled by the second output terminal of the P-type comparator and the output terminal of the first inverter, respectively, so that the second voltage line charges/discharges the output load.
