Abstract: A display panel includes a first display area and a second display area. 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.

Abstract: A display device includes a display panel, a first protective member, and a second protective member. The display panel includes a front part, a first side part extending from the front part, and a pad portion extending from the first side part. A pad is on the pad portion, the first side part is bent, and each of the front part and the first side part displays an image. The first protective member is below the display panel and overlaps the front part and the first side part. The second protective member is below the display panel, in a same layer as the first protective layer, and overlaps the pad portion. The second protective member has a bending stiffness greater than a bending stiffness of the first protective member.
