Abstract: A display device includes: a display panel including a first area and a second area, wherein the first area includes first sub-pixels, and the second area includes second sub-pixels; and a power supply unit that generates a first driving voltage and a second driving voltage greater than the first driving voltage to supply the first and second driving voltages to the display panel. The first sub-pixels receive the first driving voltage, and the second sub-pixels receive the first driving voltage or the second driving voltage.
