DISPLAY DEVICE AND METHOD OF COMPENSATING DATA FOR THE SAME

A display device includes a data compensator to generate output image data by adding an extension bit to input image data received from an external processor, a data driver to supply a data voltage corresponding to the output image data to each of data lines, and a pixel unit including a plurality of sub-pixels. A first data line for providing a first color data signal is connected to a first sub-pixel disposed in an odd-numbered pixel row through a first anode, and is connected to a second sub-pixel disposed in an even-numbered pixel row through a second anode having a different size than the first anode, and the data compensator is configured to add a first extension bit to the input image data corresponding to the first sub-pixel and add a second extension bit to the input image data corresponding to the second sub-pixel.
