POLYMERIZABLE LIQUID CRYSTAL COMPOSITION, OPTICAL ANISOTROPIC MATERIAL, OPTICAL ELEMENT, AND OPTICAL HEAD DEVICE |
摘要 |
To provide optical elements such as a phase plate suitably used in a broadband range and a polarizing diffraction element excellent in diffraction efficiency, a polymerizable liquid crystal composition to be used for them, and an optical head device using them. A polymerizable liquid crystal composition containing a polymerizable compound having a mesogen structure comprising the following condensed benzene ring group (A) and the following 6-membered cyclic group (B) bonded to at least one bond in the group (A) directly or via a connecting group -OCO- or -COO-, and a monovalent terminal group bonded to each of both terminals of the mesogen structure, at least one of the terminal groups being a monovalent organic group having a polymerizable moiety:
condensed benzene ring group (A): a naphthalenediyl group having bonds at 1-position and at 4- or 5-position, or an anthracenediyl group having bonds at 1- or 9-position and at 4-, 5- or 10-position;
6-membered cyclic group (B): a 1,4-phenylene group, a trans-1,4-cyclohexylene group or a bivalent group having at least two groups selected from these groups bonded directly or via a connecting group. |
