An ultra thin transflective achromatic film laminate with quarter wavelength phase difference and a manufacturing method thereof are provided to reduce the thickness of the film laminate and to keep a wavelength range with the achromatic characteristic over the predetermined level. An ultra thin transflective achromatic film laminate with quarter wavelength phase difference is composed of a lower photo-alignment film(15); a lower phase difference film layer(14) coated on the lower photo-alignment film; an intermediate photo-alignment film(13) coated on the lower phase difference film layer; and an upper phase difference film layer(12) coated on the intermediate photo-alignment film. The upper and lower phase difference film layers comprise liquid crystals. The upper and lower photo-alignment films are formed by dissolving multi-ring compounds having a photoreaction group at a main chain, and a crosslinking agent in a solvent, coating, drying, and UV(Ultraviolet)-curing the dissolved material. |
