Abstract: The present disclosure relates to a display panel, and a display device and a mobile terminal including the same. The display panel includes a first pixel area, a second pixel area, and a boundary pixel area disposed between the first pixel area and the second pixel area. The boundary pixel area includes a plurality of first emission regions and a plurality of second emission regions. The maximum luminance of the first emission region decreases as the distance from the second pixel area increases, and the maximum luminance of the second emission region increases as the distance from the second pixel area increases.
