Abstract: According to an aspect, a display device includes: a display surface on which pixels each including sub-pixels of a plurality of colors are two-dimensionally arrayed; a reflective member; a first substrate provided with the reflective member; a second substrate arranged to face the first substrate; a color filter provided with filters of at least two colors corresponding to the sub-pixels; and a scattering member provided on the second substrate. A main viewing angle direction of the display device is a direction intersecting with the display surface. The color filter is formed such that 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 main viewing angle direction in a direction parallel to the display surface.

Abstract: Disclosed herein is a display device including a reflection type image display portion having a sheet-like anisotropic scattering member. In an area, in an in-plane direction, of the anisotropic scattering member, a low-refractive index area and a high-refractive index area are disposed in a mixture style. The anisotropic scattering member is disposed so that a light is scattered when an outside light is made incident from a surface side on which a degree of a change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area is relatively large, and is emitted from a surface side on which the degree of the change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area is relatively small.

Abstract: A reflective liquid crystal display device includes a first substrate provided with a reflective electrode, a second substrate provided with a transparent electrode, a liquid crystal layer disposed between the first substrate and the second substrate, and an anisotropic scattering member formed on the second substrate. The anisotropic scattering member has first and second surfaces each including a first refractive index region and a second refractive index region having a refractive index different from that of the first refractive index region. A refractive index difference between the first refractive index region and the second refractive index region in the first surface is larger than that in the second surface. The anisotropic scattering member is disposed so that light enters from the first surface thereof and the light exits as scattered light from the second surface thereof. A phase difference is given to the light entered the anisotropic scattering member.
