REVERSE WAVELENGTH DISPERSION RETARDATION FILM, POLARIZING PLATE AND DISPLAY APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reverse wavelength dispersion retardation film which can be easily manufactured and shows satisfactory reverse wavelength dispersion characteristics for its thickness.

SOLUTION: Liquid crystal monomer having a fluorene skeleton of a cardo-structure part and principal chain mesogene combining with the cardo-structure part and having a polymerizable group at the terminal is immobilized while maintaining such an orientation that the optical axis of the principal chain mesogene is made parallel to the alignment direction of an alignment film and the cardo-structure part is aligned orthogonal to the alignment direction of the principal chain mesogene, thereby obtaining the reverse wavelength dispersion retardation film.
