  • MULTILAYER AND SINGLE LAYER CELLULOSE ESTER FILMS HAVING REVERSED OPTICAL DISPERSION
    Publication number: 20140168770
    Abstract: The present invention relates to a single layer mixed cellulose ester film having a reversed optical dispersion. The mixed cellulose ester material has a DSOH from 0.35 to 1.35. By manipulating the thickness of the film, and the film stretching conditions, desirable optical retardation and optical dispersion properties can be obtained. The film can be used as an optical waveplate in liquid crystal displays to improve viewing angle, contrast ratio, and color shift.
