1. A display device, comprising:
a display panel which includes a plurality of sub pixels, each of the plurality of sub pixels including an upper sub pixel and a lower sub pixel which share a data line and are adjacent to each other; and
a data driver which converts only image data corresponding to any one of even-numbered grayscale levels and odd-numbered grayscale levels among 10-bit image data into a converted data voltage, and supplies the converted data voltage to the plurality of sub pixels,
wherein when the data driver converts only the even-numbered grayscale levels of the image data into the converted data voltage and a sub pixel of the plurality of sub pixels displays an X grayscale level, the data driver supplies an X−1 gray scale level of data voltage to the upper sub pixel and supplies an X+1 grayscale level of the data voltage to the lower sub pixel, and
wherein X is an odd number.
