Abstract
Provided is an optically anisotropic layer with which an image display device having suppressed occurrence of oblique light leakage can be manufactured; and an optical film, a polarizing plate, and an image display device, each having the optically anisotropic layer. The optically anisotropic layer is obtained by curing a polymerizable liquid crystal composition including a predetermined rod-like liquid crystal compound and a predetermined monofunctional compound, and immobilizing an alignment state of the rod-like liquid crystal compound, in which a number a1 of atoms of the rod-like liquid crystal compound and a number a2 of atoms of the monofunctional compound satisfy a relationship of Expression (1): 0.2<a2/a1≤0.68, and the rod-like liquid crystal compound is immobilized in a state of being vertically aligned with respect to the main surface of the optically anisotropic layer.
