Provided is a circuit for generating a gamma data voltage. The circuit includes a first gamma part which outputs a gamma reference voltage for a predetermined reference gray based on a brightness control signal, a second gamma part which outputs a gamma selection voltage for the reference gray based on the brightness control signal, and a brightness control part which receives the gamma reference voltage and the gamma selection voltage and selects a gamma point voltage for the reference gray having a data value between the data value of the gamma reference voltage and the data value of the gamma selection voltage. The circuit for generating a gamma data voltage according to an embodiment of the present invention can provide a gamma point voltage which changes to correspond to the variation of the data value of the brightness control signal by the first gamma part, the second gamma part, and the brightness control part. |
