Display device

摘要

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.

1. A display device comprising:
a reflective image display unit that reflects external light on a reflecting part; and an anisotropic scattering member disposed on the reflecting part, wherein the anisotropic scattering member
transmits external light incident at an incident angle θ, toward the reflecting part,transmits the external light reflected by the reflecting part, andemits the transmitted external light to scatter in a range from |θ|−φ to |θ|+φ around a direction of angle θ such that a transmittance of the reflected light through the anisotropic scattering member in a range from |θ|−φ to |θ| is no more than 10%, and wherein 2φ represents a scattering angle range, and θ represents a predetermined main incident angle of light entering the scattering member.
