1. A display apparatus comprising:
a display panel including a normal pixel and an abnormal pixel having a driving voltage range different from the normal pixel;
a gate driver configured to apply a gate signal to the display panel;
a gamma reference voltage generator configured to output a first gamma reference voltage group and a second gamma reference voltage group;
a data driver configured to output a first data voltage based on the first gamma reference voltage group and a second data voltage based on the second gamma reference voltage group; and
a driving controller configured to control the gate driver, the gamma reference voltage generator and the data driver,
wherein the normal pixel receives the first data voltage and the abnormal pixel receives the second data voltage, and
wherein a first voltage range of the first gamma reference voltage group is inconsistent with a second voltage range of the second gamma reference voltage group.
