1. A gamma voltage generation circuit comprising:
a reference voltage generator including a first reference voltage generation circuit which generates a first reference voltage based on a first source voltage and a second reference voltage generation circuit which generates a second reference voltage based on the first source voltage;
a first reference voltage corrector which generates a first corrected reference voltage by correcting the first reference voltage using a ground voltage and an external power voltage provided from an outside;
a second reference voltage corrector which generates a second corrected reference voltage by correcting the second reference voltage using a target voltage and the external power voltage; and
a gamma voltage output unit which generates a plurality of gamma voltages by dividing the first and second corrected reference voltages,
wherein the first reference voltage corrector sets the target voltage based on the first reference voltage and a ground voltage.
