Claim:
1. A display device comprising: a light source; an image analysis section an image signal generation section which generates a signal value for a fourth subpixel on the basis of the expansion coefficient after the determined process, which generates a second image including the signal values for the first subpixel, the second subpixel, the third subpixel, and the fourth subpixel, and which outputs the second image to a display side; and a light source control section which generates, on the basis of the luminance control signal after the determined process, a drive signal for making the light source emit light and which supplies the drive signal to the light source, wherein the image analysis section: has a first mode and a second mode as luminance setting modes of the light source; and sets, in order to exercise variable control of the reach time taken to change the luminance of the light source to the determined value, the reach time on the basis of the first mode for a determined period at the time of switching from the first mode to the second mode.
