1. A curved and flat combined display device comprising:
a display panel having a flat area and a curved area separated from each other, and including pixels arranged in the flat area and the curved area to display an image;
a compensation value generator configured to compare curved area data of an image data input from an external system with curved area data of imaged data generated by capturing the display panel, and generate compensation value data for the curved area of the display panel based on a comparing result; and
a controller configured to compensate for the curved area data of the image data input from the external system based on the compensation value data, and control the display panel to display the compensated curved area data of the image data,
wherein the compensation value generator correct the curved area data of the image data using the flat area data of the image data to calculate luminance compensation data for the curved area,
wherein the compensation value generator correct the curved area data of the imaged data based on the flat area data of the imaged data to calculate stain compensation data for the curved area, and
wherein the compensation value generator generate the compensation value data as a value obtained by dividing the stain compensation data by the luminance compensation data.
