摘要： The present application provides an optical film. By controlling transmittance of a liquid crystal layer comprising a radical initiator for the maximum absorption wavelength of the radical initiator, the present application can provide an optical film having a liquid crystal layer having excellent resistance to external stimuli and excellent optical properties. Such an optical film can have various forms and can be used in various fields.
