  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 —SO 3 M 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.

  提供的是一种三维控制折射率的薄偏振膜。本发明提供了一种偏振膜，包括至少一种多环化合物，其中包含一个具有折射率椭球体的—SO3M基团和/或—COOM基团，其满足一个表示为nx>nz>ny的关系，其中M表示一个离子。由于这种偏振膜具有高的平面折射率，因此与传统的偏振膜相比，其厚度大大降低，并且可以获得所需的延迟值。

  Provided is a production method for a thin birefringent film with a satisfactory alignment property, in which a refractive index is controlled three-dimensionally and optical properties are unlikely to decrease in the case where the birefringent film is placed under high temperature and high humidity. The production method for a birefringent film of the present invention includes: the step (1) of preparing a solution that exhibits a nematic liquid crystal phase, containing at least one kind of polycyclic compound containing a —SO 3 M group and/or a —COOM group (M represents a counter ion) and a solvent; the step (2) of preparing a base material at least one surface of which is subjected to a hydrophilization treatment; and the step (3) of applying the solution prepared in the step (1) to the surface of the base material prepared in the step (2), the surface being subjected to the hydrophilization treatment, followed by drying, in which a contact angle of water at 23° C. on the surface of the base material prepared in the step (2), the surface being subjected to the hydrophilization treatment is 45° or less.
