An organic light emitting device having an organic light emitting diode (OLED) panel that displays an image corresponding to a data signal, a data driver that receives image data and a gamma voltage and generates the data signal, and a gamma voltage generator that generates a gamma voltage corresponding to one selected from a plurality of gamma sets corresponding to a plurality of coordinates on the color coordinate system, wherein when a first gamma set corresponding to a first coordinate on the color coordinate system and the image data corresponds to the first coordinate, and the OLED panel displays an image corresponding to a second coordinate different from the first coordinate, the gamma voltage generator generates the gamma voltage corresponding to a second gamma set corresponding to a third coordinate symmetrical to the second coordinate with respect to the first coordinate.
