Abstract: According to one embodiment, a light control device includes a first substrate including a plurality of first control electrodes disposed in an effective area, and a plurality of feed lines disposed in a peripheral area, a second substrate, and a first liquid crystal layer. The first control electrodes are transparent electrodes. Each of the first control electrodes includes, in the effective area, first segments crossing a first direction at a first angle, second segments crossing the first direction at a second angle, and third segments crossing the first direction at a third angle. The first control electrode is electrically connected to the feed line. The first to third angles are different from each other.

Abstract: According to an aspect, a display device includes: a first translucent substrate; a second translucent substrate facing the first translucent substrate; a liquid crystal layer including polymer dispersed liquid crystal sealed between the first and second translucent substrates; at least one light emitter facing at least one of side surfaces of the first and the second translucent substrates; and a display controller. The display controller includes: an external light analyzer setting, in accordance with a received signal of external light information, a second color gamut different from a first color gamut displayable when the external light is not present; and a signal adjuster converting in color a first pixel input signal into a second pixel input signal that reduces a color shift of a second reproduced color in the second color gamut from a first reproduced color in the first color gamut in accordance with the first pixel input signal.

Abstract: A display device includes: an image display panel including a plurality of pixels each including first to fourth sub-pixels; and a signal processing unit. The signal processing unit determines an expansion coefficient related to the image display panel, obtains output signals of the first to the third sub-pixels based on at least input signals of the first to the third sub-pixels and the expansion coefficient to be output to the first to the third sub-pixels respectively, obtains a fourth sub-pixel correction value as a correction value of an output signal of the fourth sub-pixel based on the input signals of the first to the third sub-pixels and the expansion coefficient, and obtains the output signal of the fourth sub-pixel based on the input signals of the first to third sub-pixels, the expansion coefficient, and the fourth sub-pixel correction value to be output to the fourth sub-pixel.
