Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a substrate including a first area and a second area adjacent to the first area, the first area includes first pixels arranged at a first pixels per inch (PPI) and the second area includes second pixels arranged at a second PPI that is less than the first PPI;
a data line connected to pixels of the first area and the second area;
a gamma compensation voltage generator that divides a reference voltage and outputs a gamma compensation voltage based on the divided reference voltage; and
a data driver that converts pixel data into the gamma compensation voltage and outputs a data voltage to the data line,
wherein the reference voltage varies between a first voltage level and a second voltage level that is different from the first voltage level in a boundary area between the first area and the second area that share a same data line such that at least one of the second pixels from the second area is applied a data voltage according to the reference voltage having the second voltage level and at least one of the first pixels from the first area that shares the same data line as the at least one of the second pixels is applied a data voltage according to the reference voltage having the first voltage level, a range of the data voltage applied to the second pixels is greater than a range of the data voltage applied to the first pixels.
