<p>Disclosed is a gamma voltage generating circuit which generates a gamma voltage to be supplied to a source driver as a driving circuit of a display panel. The gamma voltage generating circuit according to an embodiment of the present invention includes: a voltage distributing part which generates distribution voltages through a voltage distribution between power voltages, a gamma selecting part which selects a plurality of voltage pairs among the distribution voltages in response to gamma selection signals, a gamma buffer part which generates a plurality of gamma reference voltages based on each voltage pair and controls the offset of each gamma reference voltage according to a corresponding offset control signal, and a gradation distributing part which generates the gamma voltages through a voltage distribution between the gamma reference voltages.</p> |
