A display device includes: an image display unit in an image display region, the image display unit including a plurality of main pixels each including sub-pixels; a light source portion that irradiates the image display region; a signal correction unit that calculates saturation and value of the main pixels based on first color information to be displayed on a predetermined pixel, the first color information being obtained based on an input video signal, and generates second color information by correcting the first color information based on the calculated saturation and value; a signal generation unit that calculates the saturation and the value of the main pixels based on the second color information, and generates a signal for determining light source luminance of the light source based on the calculated saturation and value; and a light source control unit that controls luminance of the light source based on the signal.
