A display device may include a plurality of pixels. Each of the plurality of pixels may include a plurality of stages electrically connected in series. Each of the plurality of stages may include a plurality of light emitting elements. A storage component may store location information of a defective pixel having a defect in the plurality of stages. A compensation component may generate compensated data by compensating for a grayscale value in image data of a normal pixel based on a first degradation coefficient, and by compensating for a grayscale value of the defective pixel corresponding to the location information based on a second degradation coefficient different from the first degradation coefficient, and thus generate compensated data. A data driver may generate data voltages based on the compensated data, and provide the data voltages to the plurality of pixels.
