A plurality of base pixel parts are disposed in the second display area, and each base pixel part includes “k” first color light emitting elements. A controller receives image signals, and the image signals include first image signals corresponding to the first display area and second image signals corresponding to the second display area. The second image signals are divided into a plurality of base signal parts respectively corresponding to the plurality of base pixel parts, and each base signal part includes “m*n” first color image signals. The controller generates color image data by rendering “p” color image signals of “m*n” color image signals included in a corresponding base signal part and “(m*n)−p” referenced image signals included in a referenced signal part adjacent to the corresponding base signal part.
