1. A display device comprising:
a display panel including a pixel;
a gate driver configured to provide a gate signal to the pixel;
a compensation data memory configured to store compensation data;
a driving controller configured to compensate for input image data based on the compensation data to generate a data signal;
a data driver configured to generate a data voltage based on the data signal to provide the data voltage to the pixel;
wherein the compensation data include a first captured image corresponding to reference data having a reference grayscale, a second captured image corresponding to evaluation data having a compensation target grayscale, a similarity index calculated based on the first captured image and the second captured image, a quality index calculated based on an actual measured grayscale of the second captured image after compensation of the second captured image, and a compensation value determined based on a compensation prediction model generated based on the similarity index and the quality index.
