Abstract
Provided are an output buffer circuit having an amplifier offset compensation function and a source driving circuit including the output buffer circuit. The output buffer circuit may include a plurality of channel amplifiers, each of which is configured to adjust an amount of current flowing through transistors connected to at least one of a non-inverted input terminal and an inverted input terminal of a differential input unit to compensate an amplifier offset, and adjust buffer input voltage signals to generate output voltage signals.
