Document Type and Number:
Japanese Patent JP2692035
Kind Code:
B2
Abstract:
PURPOSE:To obtain a thin film capable of providing an optically anisotropic sheet excellent in thermal durability and in monodomain property, and a phase difference film enabling the remarkable improvement in the angle of visibility used for liquid crystal elements by adding light or heat energy to a thin film containing a specific disk-like compound formed on a support. CONSTITUTION:A light or heat energy is added to (C) a thin film containing (B) at least one kind of disk-like compound having a substituent capable of polymerizing by the addition of light or heat energy and formed on (A) a support to obtain the objective thin film. A thin film having an optically anisotropic molecular configuration or a thin film forming a discotic nematic liquid crystal phase is preferably used as the component C, and a compound of the formula [D is an n-valent functional group at the center of the molecule and radially having substituents of R and substituents of (P-L) in a total number of (n); kXP groups are isocyanate groups, etc.; (n-k)R groups are functional group not contributing to the polymerization composition; L is a bonding group connecting L to P and D, etc.], is preferably used as the component B.
