    摘要: A method for producing an optical laminate including a film substrate and a polarizing layer which comprises the steps of: (A) laminating a re-releasable film on one main surface of the film substrate to obtain a laminate film substrate; B) performing a rubbing treatment on the other main surface of the film substrate of the laminate film substrate; C) coating the rubbing-treated surface of the film substrate with a solution containing a lyotropic liquid crystal compound and a solvent; and D) detaching the re-releasable film from the laminate film substrate.

    摘要: The present invention provides a birefringent film that hardly generates cracks even when the film is exposed under a high-temperature and high-humidity environment for a long period of time. The birefringent film of the present invention is a film containing, as a major component, a lyotropic liquid crystalline polycyclic compound containing an acenaphtho[1,2-b]quinoxaline derivative unit in a molecular structure and having a molecular weight of 500 or higher. The birefringent film of the present invention preferably has a refractive index ellipsoid showing a relationship of nx≧nz>ny, and more preferably has an in-plane birefringence of 0.01 or higher at the wavelength of 590 nm.

    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.
