Spontaneous alignment method for manufacturing cholesteric reflective polarizer |
摘要 |
To form a brightness enhancement film of cholesteric liquid crystal, a photopolymerizable liquid crystal is first formed on a first substrate. A second substrate then is formed on the liquid crystal substance to form a sandwich structure. The sandwich structure is subsequently submitted to a lamination process that generates shear stress thereon. Finally, an energetic irradiation including UV irradiation is performed to solidify the layer of liquid crystal into a liquid crystal polymer film. The second substrate then is selectively removed. The above steps are repeated until a desired reflected wavelength range of the liquid crystal film is obtained.
