    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.

    Abstract: A display device includes a display surface with pixels including four sub-pixels of four colors, and being arrayed in a matrix of a first viewing angle direction and a second viewing angle direction orthogonal thereto. The first viewing angle direction in a direction parallel to the display surface of a main viewing angle direction that intersects with the display surface. A reflective member, first substrate, a second substrate facing the first substrate, a color filter with filters of four colors corresponding to the four sub-pixels, and a scattering member is provided on the second substrate. For the color filter, a change in transmittance of the filters per pixel in the main viewing angle direction is smaller than a change in transmittance of the filters per pixel in a direction orthogonal to the first viewing angle direction in the second viewing angle direction parallel to the display surface.

    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).
