Abstract:
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.
