A display device includes a pixel component including a first pixel area in which pixels are disposed at a first density, and a second pixel area in which the pixels are disposed at a second density less than the first density, and a grayscale compensator which converts input grayscale values for the first pixel area to output grayscale values within a first grayscale range, and converts the input grayscale values for the second pixel area to the output grayscale values within a second grayscale range. An upper limit of the second grayscale range is greater than an upper limit of the first grayscale range.
