Abstract:
The purpose of the present invention is to provide a laminate which has an alignment film that makes it possible to increase the degree of alignment of a liquid crystal layer, an image display device, an optical device, and a head-mounted display. The laminate according to the present invention comprises the alignment film and a liquid crystal layer adjacent thereto. The alignment film contains a cured substance of a compound A which is expressed by a predetermined formula and in which a ratio of the number of aromatic rings to the total number of ring structures that do not have ring-opening polymerizability is 70% or more. The ratio of the number of aromatic rings to the total number of ring structures that do not have ring-opening polymerizability in the compound A is 70% or more. An angle formed between the alignment direction of a liquid crystal compound contained in the liquid crystal layer and the normal direction of the liquid crystal layer is 0°-45° inclusive.
