1. A display device comprising:
a display panel which displays an image; and
a panel driving block which receives a control signal and generates a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal, wherein the criterion point is a point where a gaze of a user is most focused among the display panel when the image is displayed,
wherein the panel driving block receives image signals corresponding to the image displayed on the display panel, generates a correction value of each of the image signals based on distance information between the criterion point and a location of the display panel, at which each of the image signals is displayed, and a frequency of the gaze of the user in a direction of the location of the display panel, at which each of the image signals is displayed, with respect to the criterion point, and generates correction image signals by converting each of the image signals based on the correction value thereof,
wherein the display panel displays the image corresponding to the correction image signals, and
wherein the luminance of the image is adjusted based on the distance information.
