<P>PROBLEM TO BE SOLVED: To provide an optical film having high retardation, high moisture/heat resistance, and brittleness. <P>SOLUTION: The optical film includes cellulose ester and a compound represented by a formula (1). (In the formula, L<SB POS="POST">11</SB>indicates a single bond or -NR<SB POS="POST">1</SB>-; A<SB POS="POST">11</SB>indicates an aryl containing group or a heteroaryl containing group; L<SB POS="POST">12</SB>indicates a single bond or -NR<SB POS="POST">3</SB>- or the like; A<SB POS="POST">12</SB>indicate an aryl containing group, a heteroaryl containing group or the like; L<SB POS="POST">13</SB>indicates a single bond or -NR<SB POS="POST">3</SB>- or the like; A<SB POS="POST">13</SB>indicates an aryl containing group, a heteroaryl containing group etc or the like; R<SB POS="POST">1</SB>to R<SB POS="POST">3</SB>indicate hydrogen atoms, C1 to C6 alkyl group, or an aryl group; and R<SB POS="POST">12</SB>indicates a hydrogen atom, hydroxyl group or the like.) <P>COPYRIGHT: (C)2013,JPO&INPIT |
