Abstract:
1. A display device comprising a reflective image display unit including a sheet-like anisotropic scattering member, wherein 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 of the sheet-like anisotropic scattering member and exits as scattered light from a second surface of the sheet-like anisotropic scattering member, 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, and the display device satisfies mathematical formulae, wherein 2φ represents a scattering angle range, θ represents a predetermined main incident angle of light entering the scattering member, T(a) represents a transmittance at a position on an extension line of an incident direction of the light with an incident angle “a”.
