Abstract
Provided is an optically anisotropic sheet that gives a thin optically anisotropic film that can be transferred to a display device. The optically anisotropic sheet includes a substrate, a liquid crystal cured film, and a sticky adhesive layer in this order. The liquid crystal cured film is a film that has a thickness of 5 μm or less and is cured with a polymerizable liquid crystal compound aligned. The sticking force (F1) between the liquid crystal cured film and the sticky adhesive layer is greater than the substrate sticking force (F4).
