The present invention relates to novel photoactive polymer materials their use as orienting layer for liquid crystals, which are used for the production of non-structured and structured optical elements or electro-optical elements and multi-layer systems.

A curved-surface liquid crystal display panel and a display device are disclosed. The curved-surface liquid crystal display panel includes an array substrate and an opposite substrate, a liquid crystal layer including first liquid crystal molecules, a lower polarizer, an upper polarizer, a lower compensation layer, and an upper compensation layer. Each of the upper compensation layer and the lower compensation layer includes second liquid crystal molecules having a birefringence different from that of the first liquid crystal molecules. A direction of pre-tilt angles of the second liquid crystal molecules in the upper compensation layer and a direction of a light absorption axis of the upper polarizer forms a non-zero first angle, and the direction of pre-tilt angles of the second liquid crystal molecules in the lower compensation layer and a direction of a light absorption axis of the lower polarizer forms a non-zero second angle.

A compensation film satisfies Inequalities 1 and 2, and an antireflective film and a display device are provided with the compensation film.

A liquid crystal device includes a liquid crystal panel having a liquid crystal layer between an element substrate (first substrate) and a counter substrate (second substrate), and a translucent substrate disposed on a surface of the element substrate which is opposite to the counter substrate. An optical compensation layer which includes a first phase difference compensation element and a second phase difference compensation element formed of an oblique deposition film is integrally laminated on the substrate surface of the translucent substrate which is opposite to the liquid crystal panel. An alignment direction P of the liquid crystal molecules in plan view is a direction between an oblique deposition direction (first direction) of the first phase difference compensation element and an oblique deposition direction (second direction) of the second phase difference compensation element.

Disclosed is an optical compensation film including a supporter, and an optical compensation layer disposed on at least one surface of the supporter and including a polymer of cholesteric liquid crystal molecules having a structure in which a plurality of parallel-arranged liquid crystal molecules are helically arranged, wherein the cholesteric liquid crystal layer has a helical axis that is bent and tilted to the supporter at an angle represented by the following Equation 1; a method of manufacturing the same; and a liquid crystal device (LCD) including the optical compensation film.
H=(.sub.T.sub.B)*(d/d).sup.+.sub.B[Equation 1]
In Equation 1, H is a tilt angle of the helical axis of a layer of the cholesteric liquid crystal molecules; .sub.B is a tilt angle of liquid crystal molecule contact with the supporter; .sub.T is a tilt angle of a liquid crystal molecule disposed at a part of the layer furthest from the supporter; d is a thickness of the layer; d is a distance from the supporter along a vertical direction; is a degree of variation in tilt angle of helical axis; and 0.01.
