    Abstract: A laminate film comprising a retardation layer exhibiting blocking characteristics against specific ultraviolet rays even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The laminate film which can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The laminate film can also be formed with a lower thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the laminate film exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.

    Abstract: An optical element and a use of the optical element are provided. The exemplary optical element can be useful in realizing a smart blind having excellent transmission and blocking characteristics in front and lateral surfaces thereof without using a retardation film by employing a polarizing layer whose polarization characteristics are patterned using a guest/host-type dye layer including a polymerizable liquid crystal compound and a dichroic dye. Such an optical element may be applied to various light modulating devices such as smart blinds, smart windows, window protective films, flexible display elements, active retarders for displaying a 3D image, or viewing angle adjustment films.

    Abstract: 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.

    Abstract: The present application relates to a liquid crystal composition, a polarizing element and a use of the polarizing element. Since the polarizing element may be prepared by a simple coating process, the guest host type liquid crystal composition of the present application allows not only for reducing the manufacturing cost and lightweight thinning of the polarizing element, but also for manufacturing the polarizing element showing an excellent heat resistant stability without changes of absorption spectrum to transmission spectrum even in a severe condition such as high temperature environment. Such a polarizing element can be applied to various display devices such as liquid crystal display devices, EL display devices, field emission display devices, display devices using electronic papers, projection display devices or piezoelectric ceramic display devices.
