Abstract: Disclosed is a display device comprising: a display panel on which a plurality of pixels of different colors are arrayed; a power supply configured to supply a high-potential driving voltage to the display panel; and a data driver configured to calculate an average picture level of input image data, and generate a data voltage based on a compensation value for compensating for a voltage drop of the high-potential driving voltage based on the calculated APL, wherein the compensation value is independently set for each of the colors.
