Abstract: The present disclosure relates to a display device and a driving method of a display device. The display device includes a display panel including a first display area and a second display area; a data correcting unit which is applied with n-bit input image data to generate (n-a)-bit corrected image data; a timing control unit which is applied with the (n-a)-bit corrected image data to generate (n-a)-bit output image data; and a data driving unit which is applied with the (n-a)-bit output image data to output a first data voltage to a first pixel disposed in the first display area and output a second data voltage to a second pixel which is disposed in the second display area and corresponds to the first pixel. Therefore, corrected image data which has a lower bit number than that of input image data is used to express the same color depth as a color depth which is expressed by the input image data so that the size of the data is reduced and the data amount processed by the timing control unit and the data driver is reduced. Therefore, the processing speed of the timing control unit and the data driver may be improved.
