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: 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.
