Abstract:
The present invention provides a liquid crystal film having an optically anisotropic layer having excellent alignment and excellent adhesiveness. The present invention further provides an optical laminate, a circularly polarizing plate, and an organic EL display device, each of which uses the optically anisotropic layer. The liquid crystal film of an embodiment of the present invention is a liquid crystal film having at least an optically anisotropic layer formed with a liquid crystal composition including a polymerizable liquid crystal compound and a fluoroaliphatic group-containing copolymer, and a support, in which the fluoroaliphatic group-containing copolymer has a repeating unit derived from a fluoroaliphatic group-containing monomer represented by General Formula (1) and a repeating unit having a polymerizable group polymerizable with the polymerizable liquid crystal compound.
