1. A display device, comprising:
a display panel including a plurality of pixels;
a data driver configured to generate an image data voltage based on compensated image data generated by compensating for input image data and to apply the generated image data voltage to the display panel; and
a deterioration compensation device configured to generate compensated image data by compensating for the input image data in response to an accumulated amount of deterioration data of the pixels and to apply the compensated image data to the data driver,
wherein the deterioration compensation device comprises: a gamma correction LUT configured to store a gamma value set for each color, each gray level, and each accumulated driving time of each of the pixels, the gamma value set storing gamma values changed according to degrees of deterioration of the pixels, and
wherein the deterioration compensation device is configured to compensate for the input image data based on the gamma values stored in the gamma correction LUT.
