<P>PROBLEM TO BE SOLVED: To provide a technology to slough off trade-off of refractive index anisotropy and wavelength dispersion characteristics and to provide a method and a material for manufacturing a substrate for a liquid crystal display having a pattern-shaped retardation. <P>SOLUTION: A composition for forming an optical anisotropic layer contains a compound represented by formula (I), a compound represented by formula (II) and a cationic polymerization initiator. A transfer material has the optical anisotropic layer and an adhesive layer for transfer. The optical anisotropic layer is formed by irradiating a liquid crystal phase with heat or an ionizing radiation after the liquid crystal phase is formed by applying and drying a solution containing the composition. In formula (I) and formula (II), either one of Q<SP>1</SP>and Q<SP>2</SP>denotes a radically polymerizable group; the other of Q<SP>1</SP>and Q<SP>2</SP>denotes a cationically polymerizable group; either one of Q<SP>3</SP>and Q<SP>4</SP>denotes a radically polymerizable group; the other of Q<SP>3</SP>and Q<SP>4</SP>denotes a cationically polymerizable group; X<SP>11</SP>and X<SP>12</SP>each independently denotes -O-, -NP<SP>1</SP>- or the like, P<SP>1</SP>, P<SP>2</SP>, P<SP>3</SP>and P<SP>4</SP>each denotes a hydrogen atom or an alkyl group; L<SP>1</SP>to L<SP>4</SP>each independently denotes a single bond or an alkylene group; A<SP>1</SP>, A<SP>2</SP>and A<SP>6</SP>each independently denotes a single bond, -O-, -O-CO- or the like; A<SP>3</SP>denotes a single bond, -O- or -CO-O-; A<SP>4</SP>and A<SP>5</SP>each independently denotes a single bond, -CO-O- or -CO-S-; A<SP>4</SP>or at least one of m A<SP>5</SP>is a single bond; R<SP>11</SP>to R<SP>16</SP>each independently denotes a hydrogen atom or a methyl group; n1 to n6 each denotes an integer of 1 to 3 and m denotes an integer of 2 to 3. <P>COPYRIGHT: (C)2009,JPO&INPIT
