A gamma tap circuit includes: (i) a first gamma division circuit configured to generate a first gamma tap voltage by performing voltage division of an upper gamma tap voltage and a lower gamma tap voltage, in-sync with a first clock signal CKand a first complementary clock signal CK, which is 180° out-of-phase relative to CK, (ii) a second gamma division circuit configured to generate a second gamma tap voltage by performing voltage division of the upper gamma tap voltage and the first gamma tap voltage, in-sync with a second clock signal CKand a second complementary clock signal CK, which is 180° out-of-phase relative to CK, and (iii) a third gamma division circuit configured to generate a third gamma tap voltage by performing voltage division of the first gamma tap voltage and the lower gamma tap voltage, in response to CKand CK, which have a lower frequency relative to CKand CK
