Abstract: According to an aspect, a display device includes: an image display panel in which pixels are arranged in a two-dimensional matrix, each of the pixels including a first sub-pixel displaying a first color, a second sub-pixel displaying a second color, a third sub-pixel displaying a third color, and a fourth sub-pixel displaying a fourth color; and a signal processing unit that converts input values of input signals into extended values in an extended color space to generate output signals, and outputs the generated output signals to the image display panel. The signal processing unit changes the output signals for the first to fourth sub-pixels based on at least saturation of the input signals.

Abstract: According to an aspect, a reflective liquid-crystal display device includes a liquid-crystal panel and a front light unit. The liquid-crystal panel includes a sheet-like anisotropic scattering member having low refractive index areas and high refractive index areas with a refractive index higher than that of the low refractive index areas. The front light unit includes a light guide plate laminated on the liquid-crystal panel and having a number of grooves formed on a surface facing the liquid-crystal panel at a pitch of equal to or smaller than 100 □m and a light source that makes light incident on the light guide plate. An arrangement interval of the unit pixels is larger than an average of an arrangement interval of the high refractive index area of the anisotropic scattering member.

Abstract: According to an aspect, a display device includes a plurality of pixels each including a plurality of sub-pixels. Each of the sub-pixels is arranged around center of the corresponding pixel and divided into a plurality of display regions to perform N-bit area coverage modulation by a combination of the display regions. The display regions are arranged in such a manner that: a display region corresponding to a least significant bit of the area coverage modulation is arranged closest to the center of the corresponding pixel; and a display region corresponding to a higher significant bit of the area coverage modulation is arranged around the center of the pixel and further from the center of the corresponding pixel (N is a natural number of 2 or more).

Abstract: According to an aspect, a transflective liquid crystal display device includes: a first substrate on which reflective electrodes are arranged for pixels; a second substrate on which a transparent electrode is provided; a liquid crystal layer between the first and the second substrates; and a color filter that is provided closer to the transparent electrode than the reflective electrodes, and includes filters of a plurality of colors. The first substrate is provided with a first space between reflective electrodes of adjacent pixels and a second space between reflective electrodes of adjacent pixels, the first space extending in a first direction and overlapping a border between filters of different colors, the second space extending in a second direction and having transmittance higher than that of the first space. Transmissive display is performed by using the second space where a light shielding member is not positioned.

Abstract: A display device includes a reflective image display unit having a sheet-like anisotropic scattering member. The sheet-like anisotropic scattering member has a surface in which both a low refractive index area and a high refractive index area exist. The sheet-like anisotropic scattering member is disposed so that a light enters from a first surface thereof and exits as scattered light from a second surface thereof, when an extent of refractive index difference at a boundary or vicinity thereof between the low refractive index area and the high refractive index area is relatively large in the first surface and relatively small in the second surface.
