A display apparatus is provided to easily set a data voltage by generating gamma reference voltages based on distribution of a voltage between a driving voltage and an inverse voltage of the driving voltage. A display apparatus includes a display panel, a voltage generator(240), an inverse voltage generator(270), a gamma reference voltage generator(260), and a data driver(250). The display panel includes display regions defined by gate and data patterns. The voltage generator generates driving voltages including a first gamma driving voltage. The inverse voltage generator generates a second gamma driving voltage using one of the driving voltages. The gamma reference voltage generator generates plural gamma reference voltages(VREF) based on distribution of a voltage between the first and second gamma driving voltages. The data driver converts a data signal into an analog data voltage and outputs the data voltage to the data patterns.
