Abstract: The present disclosure relates to a display panel and a display device using the same. Between first and second pixel areas having different pixels per inch, a third pixel area is provided to have the same pixels per inch as the first pixel area. In the third pixel area, some of pixels emit light as ON pixels, and remaining background pixels except for the ON pixels are driven as OFF pixels or low luminance pixels.
