Abstract: A display device includes a display panel which displays an image, and a panel driving block which receives a control signal and generating a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal. The panel driving block receives image signals, generates a correction value based on distance information about a location of the display panel, at which each of the image signals is displayed, and the criterion point, and generates correction image signals by converting the image signals based on the correction value.
