Abstract: A display device and a driving method thereof. The display device includes a color controller configured to generate second image data by converting the color gamut of first image data received from the outside and to generate third image data by correcting the first image data or the second image data depending on the viewing angle variation between the first image data and the second image data, and a display panel configured to display an image based on the second image data or the third image data.
