Title:
OPTICAL LAMINATE, IMAGE DISPLAY DEVICE, AND GLASS COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2021/210359
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an optical laminate that can sufficiently block light emitted in a direction oblique to the normal direction of a film and that generates no moire even when used in combination with a high-resolution image display device; an image display device; and a glass composite. At least a first light-absorbing anisotropic layer, a refractive index anisotropic layer that contains a liquid crystal compound having a twist structure of one or more layers, and a second light-absorbing anisotropic layer are provided in this order. The first light-absorbing anisotropic layer and the second light-absorbing anisotropic layer contain anisotropic absorption materials, and the absorption axis is oriented at an angle of 60-90 degrees with respect to a film surface.
