Display device and method of driving display device

A display device, comprising:

• a display panel including a plurality of pixels, each of the plurality of pixels including a plurality of stages electrically connected in series, each of the plurality of stages including a plurality of light emitting elements;
• a storage component that stores location information of at least one defective pixel having a defect in the plurality of stages among the plurality of pixels;
• a compensation component that generates compensated data by compensating for a grayscale value in image data of a normal pixel among the plurality of pixels based on a first degradation coefficient, and by compensating for a grayscale value of the at least one defective pixel corresponding to the location information based on a second degradation coefficient different from the first degradation coefficient;
• and
• a data driver that generates data voltages based on the compensated data, and provide the data voltages to the plurality of pixels,
• wherein the compensation component generates the compensated data by:
• calculating a first compensated grayscale value of the normal pixel among the plurality of pixels based on the first degradation coefficient and adding the first compensated grayscale value to the grayscale value in the image data of the normal pixel to compensate for the grayscale value of the normal pixel based on a difference between a target luminance and a first degraded luminance;
• and
• calculating a second compensated grayscale value of the at least one defective pixel corresponding to the location information based on the second degradation coefficient different from the first degradation coefficient and adding the second compensated grayscale value to the grayscale value in the image data of the at least one defective pixel to compensate for the grayscale value of the at least one defective pixel based on a difference between the target luminance and a second degraded luminance.
