摘要： A birefringent film of the present invention comprises at least one kind of polycyclic compound including a —COOM group (the M denotes a counter ion), wherein an index ellipsoid satisfies a relation of nz>nx=ny. The polycyclic compound includes, for example, acenaphtho[1,2-b]quinoxaline derivative represented by the following general formula (I). The birefringent film of the present invention can be formed thin-type and have a high birefringent index in the thickness direction, since the birefringent film comprises the polycyclic compound.

摘要： Provided is a thin birefringent film whose refractive index is three-dimensionally controlled. The present invention provides a birefringent film including at least one polycyclic compound containing a —SO3M group and/or a —COOM group having a refractive index ellipsoid satisfying a relationship represented by nx>nz>ny, in which M represents a counter ion. Since such a birefringent film has a high in-plane refractive index, the thickness thereof is sharply reduced as compared with a conventional birefringent film and a desired retardation value can be obtained.
