Abstract
A display device including a plurality of source drivers. Each of the .plurality of source drives may include a register storing information on a bias voltage provided from the outside; a gamma voltage generation unit receiving at least one reference gamma voltage and generating a plurality of gamma voltages according to the reference gamma voltage; and an output buffer including a plurality of source amplifiers driven by the bias voltage and receiving the plurality of gamma voltages. The gamma voltage generation unit may adjust a level of at lest one of the at least one reference gamma voltage, according to a bias voltage having the lowest level among bias voltages provided to respective source drivers.
