| abstract |
The present invention relates to a compound, a composition, a retardation plate, an elliptically-polarizing plate and a liquid-crystal display device. In particularly the invention provides a compound useful for fabrication of retardation plates, which is represented by the formula (DI): wherein Y<11> to Y<13> represent methine or nitrogen; R<11> to R<13> represent a group of the formula (DI-A) below or others: wherein A<11> to A<16> represent methine or nitrogen; X<1> represents oxygen, sulfur, methylene or imino; L<11> represents -O-, -C(=O)-, -O-CO-, -CO-O-, -O-CO-O-, -S-, -NH-, -SO2-, -CH2-, -CH=CH-, or -C=C-; L<12> represents a divalent linking group; Q<11> represents polymerizable group or hydrogen. |
