Abstract
The present invention aims to provide a display device capable of displaying an image in a color maintaining a hue and a tone expected from an input signal. In a field-sequential liquid crystal display device, when a red image is displayed, red light is transmitted in the first subframe period, and further, green light and blue light are transmitted in the second and third subframe periods, respectively. Therefore, the blue component of an input signal is adjusted such that the transmittance of the liquid crystal panel is at a predetermined value even in the third subframe period. As a result, the hue of an image displayed on the liquid crystal panel is the same as or almost the same as the hue of red expected from the input signal. Moreover, the color of red displayed on the liquid crystal panel maintains the tone value of the color expected from the input signal.
