Abstract: According to an aspect, a display device includes an image display panel and a signal processing unit. The signal processing unit derives a generation signal for a fourth sub-pixel in each of pixels based on an input signal for a first sub-pixel, an input signal for a second sub-pixel, an input signal for a third sub-pixel, and an extension coefficient. The signal processing unit derives a correction value based on a hue of an input color corresponding to a color to be displayed based on the input signal for the first sub-pixel, the input signal for the second sub-pixel, and the input signal for the third sub-pixel. The signal processing unit derives the output signal for the fourth sub-pixel in each of the pixels based on the generation signal for the fourth sub-pixel and the correction value and outputs the output signal to the fourth sub-pixel.

Abstract: A lighting device includes a light source including at least two types of light emitting elements with different color temperatures, an optical element including a plurality of liquid crystal cells and configured to control a distribution of light emitted from the light source, and a control unit configured to control the light source. The control unit controls the optical element to change from a first light distribution state to a second light distribution state different from the first light distribution state. The control unit controls the light source so that a color temperature of light emitted in a direction perpendicular to a surface of the optical element is the same in the first light distribution state and the second light distribution state.
