The display device includes a display configured to display an image; and a controller configured to perform image processing on the displayed such that a radius of curvature of the displayed image and a radius of curvature of a visible image are different. The image can be enlarged to a maximum area providing in the display device by applying analogous viewing distance calculation method used in the curved display device with respect to the scaling of the image. Accordingly, the discontinuity of the image can be removed by providing continuous scaling, and the perspective, presence, viewing experience can be enhanced while adaptively correcting the brightness. The display device can display the image having the curvature that the user wants, and thus resemble the curved display device. Further, optical illusion of watching the three-dimensional image can be generated.
