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 in such a way 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.

A display device comprising:

a reflection type image display portion including a sheet-like anisotropic scattering member,
wherein 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,
wherein the anisotropic scattering member includes a first surface and a second surface, the first surface having a relatively large degree of change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area, and the second surface having a relatively small degree of change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area, and
wherein the high-refractive index area has a columnar shape, and the low-refractive index area is formed in a peripheral area surrounding the high-refractive index area.
