(54) | Gamma reference voltage generating circuit and display device including the same |
(57) A gamma reference voltage generating circuit and a display device including the same are disclosed. The gamma reference voltage generating circuit include a first voltage follower (GMA1) configured to receive a first reference voltage generated by a first digital-to-analog converter (DAC1) and output a first gamma reference voltage (gamma1) and second to (n-1)th voltage followers (GMA2, GMA3 ... GMA8) each generating second to (n-1)th gamma reference voltages (gamma2, gamma3 ... gamma8) being generated based on the first gamma reference voltage output from the first voltage follower (gamma1).
