1. A display device comprising:
a display panel including a first display area and a second display area; and
a panel driving block which provides, to the first display area, a first data signal generated by converting a first image signal, which corresponds to the first display area, based on first reference color coordinates in a color space, and provides, to the second display area, a second data signal generated by converting a second image signal, which corresponds to the second display area, based on second reference color coordinates in the color space,
wherein the second reference color coordinates are color coordinates obtained by shifting the first reference color coordinates in the color space,
each of the first image signal and the second image signal includes a first color signal corresponding to a first color, a second color signal corresponding to a second color, and a third color signal corresponding to a third color,
when ratios among the first to third color included in the first image signal are equal to ratios among the first to third color included in the second image signal, ratios among the first to third color signals of the first data signal are different from ratios among the first to third color signals of the second data signals.
