1. A display device comprising:
a display panel comprising sub-pixels in a first display area, the sub-pixels comprising first sub-pixels to emit light having a first color and second sub-pixels to emit light having a second color; and
a data driver configured to generate data voltages based on data values for the sub-pixels, and to provide the data voltages to the sub-pixels,
wherein, as a first average data value of the first sub-pixels in the first display area changes, the data driver varies a black bias offset voltage of the sub-pixels in the first display area, and
wherein the black bias offset voltage corresponds to a minimum value in a range of the data values.
