PROBLEM TO BE SOLVED: To suppress deterioration of an image.SOLUTION: A display device 10 comprises: an image display panel 40 in which pixels including first to fourth sub-pixels are arranged in a two-dimensional matrix state; and a signal processing part 20 for converting an input value of an input signal having color information of a predetermined color expressed in a reference color region into a reproduction value of a reproduction color space for creating an output signal, and outputting the created output signal to the image display panel 40. The signal processing part 20 corrects the input value of the input signal to an input value of a correction input signal having color information of a correction color, so that the predetermined color becomes a correction color being a color disposed in a direction being distant from a white point for expressing a white color in the reference color region or a display color region of colors which can be expressed by the image display panel 40, determines an extension coefficient related to the image display panel 40, and determines output signals of the first to fourth sub-pixels based on at least the correction input signal and the extension coefficient. |
