摘要： The invention aims at providing a display which can improve viewing angle dependency of contrast ratio in a wide azimuth without changing design of a basic structure of a display element, impairing display quality in a direction showing large contrast ratio and being limited to a state of displaying white or black. The aim is attained by a display comprising: a display element having viewing angle dependency of contrast ratio; and an anisotropic scattering film having an anisotropic scattering layer, wherein the anisotropic scattering film has a scattering central axis approximately parallel to a direction showing the largest contrast ratio of the display element and is located on a viewing screen side of the display element.

摘要： Provided is a light diffusion film laminate for a reflective display device that can improve the reflection luminance at a predetermined observation position (for example, the front direction of the screen) without reducing the visibility not only from the predetermined observation position (for example, the front direction of the screen) but also from a position away from a predetermined observation position (for example, an oblique direction deviated from the front of the screen) and a reflective display device including the light diffusion film laminate.A light diffusion film laminate for a reflective display device has optical diffusibility that changes depending on an incident angle of light, and at least transmits reflected light occurring when incident light is reflected by a reflective layer. The light diffusion film laminate includes at least an anisotropic light diffusion layer that has a scattering central axis and whose linear transmittance changes depending on an incident light angle of the light, wherein the anisotropic light diffusion layer has a matrix region and a plurality of pillar structures, wherein an angle of the scattering central axis is in a range of +6° or more and +40° or less, or −40° or more and −6° or less with respect to a normal direction of the anisotropic light diffusion layer, and an isotropic light diffusion layer disposed on one surface of the anisotropic light diffusion layer.
