  • OPTICAL FILM AND IMAGE DISPLAY APPARATUS HAVING THE SAME
    Publication number: 20100272971
    Abstract: A novel optical film is provided that exhibits a wavelength dispersion (a reverse wavelength dispersion) such that the birefringence of the film decreases as the wavelength becomes shorter, at least in the visible light range. The optical film includes a layer formed of a resin (A) having a heteroaromatic group or a molecular structure represented by the following formula (1), (2) or (3): where in the formula (1), n is a natural number in the range of 1 to 4, and R1 and R2 each independently represent a hydrogen atom or a methyl group. The optical film exhibits a wavelength dispersion such that the birefringence of the film decreases as the wavelength becomes shorter, at least in the visible light range.
