Title:
OPTICAL FILM, OPTICAL MULTILAYER BODY, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/092154
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an optical film which enables the achievement of an image display device that is capable of achieving a good balance between anti-reflection effect for outside light and improvement of the utilization efficiency of light emitted from a light emitting element if applied to a self-luminous image display device that uses an inorganic EL element, an organic EL element and the like; an optical multilayer body; and an image display device. An optical film according to the present invention comprises a light absorption anisotropic film which is composed of a cured product of a liquid crystal composition that contains a polymerizable liquid crystal compound and a dichroic dye compound; the light absorption anisotropic film has, within a same film surface, a region A wherein the tilt of the absorption axis to the film surface is θA and a region B wherein the tilt of the absorption axis to the film surface is θB; and θA and θB satisfy the relational expressions (1) and (2). Relational expression (1): |θA - θB| ≥ 10°
Relational expression (2): 0° ≤ θB ≤ 5°
