1. A display device comprising:
a display panel comprising a surrounding display area, below which at least one panel driving circuit, which includes a scan driver and a data driver, is positioned, and a main display area surrounded by the surrounding display area, the display panel comprising first pixels disposed in the surrounding display area and second pixels disposed in the main display area; and
a display panel driver configured to divide an input image to be displayed on the display panel in each frame into a first image to be displayed in the surrounding display area and a second image to be displayed in the main display area, to determine to display the second image in the main display area, and to determine whether to display the first image in the surrounding display area,
wherein the display panel driver is configured to calculate a luminance deviation of the first image and to determine whether to display the first image in the surrounding display area based on the luminance deviation of the first image.
