摘要： The present application relates to an optical film, an optical element and an imaging device. The optical film of the present application does not only exhibit broadband polarization conversion characteristics in the visible light region, but also has absorption bands in the visible light region. Such an optical film can be applied to an imaging device such as an augmented reality apparatus as an optical element such as a diffractive light guide plate laminate to suppress crosstalk.

摘要： Provided are a liquid crystal composition, a liquid crystal film and a display device. The liquid crystal composition according to the present application may form a liquid crystal layer in which staining due to a thickness difference does not occur even in large-area coating such that a liquid crystal layer can be formed on a base layer having erosivity to a raw material since the liquid crystal composition may have a suitable solubility even in a solvent in which solubility is normally low.
