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.
