Title:
OPTICAL FILM, OPTICALLY ANISOTROPIC LAYER, ALIGNMENT FILM-FORMING COMPOSITION, METHOD FOR PRODUCING OPTICAL FILM, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/171518
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an optical film which has improved orientation of a liquid crystal compound in an optical anisotropic layer while suppressing the occurrence of bright spot defects; an optically anisotropic layer; an alignment film-forming composition; a method for producing an optical film; a polarizing plate; and an image display device. An optical film according to the present invention has an alignment film and an optically anisotropic layer, wherein: the optically anisotropic layer is a layer formed using an optically anisotropic layer-forming composition containing a polymerizable liquid crystal compound; and the alignment film is a film formed using an alignment film-forming composition containing an additive having a C5-C29 alkyl group and a polymer having no C5-C29 alkyl group.
