  • Compensator with photochemically cured barrier layer and process
    Patent number: 7148941
    Abstract: Disclosed is an optical compensator for a liquid crystal display having improved optical properties, comprising a transparent polymeric support bearing an orientation layer and a photochemically cured optically anisotropic layer, in that order, wherein a photochemically cured barrier layer is present between the orientation layer and the support, and wherein the barrier layer, as disposed on the support, exhibits an indentation modulus of less than 2 GPa.
    Type: Grant
    Filed: March 17, 2003
    Date of Patent: December 12, 2006
    Assignee: Eastman Kodak Company
    Inventors: Mridula Nair, Tamara K. Jones, Bradley M. Houghtaling, Jeffrey A. Trest, Joseph S. Sedita
  • Compensator having particular sequence of films and crosslinked barrier layer
    Patent number: 7084945
    Abstract: Disclosed is an optical compensator for a liquid crystal display comprising a transparent polymeric support, an orientation layer, and an optically anisotropic layer, in order, and located between the support and the orientation layer, a barrier layer comprising a crosslinked polymer impermeable to the components of the support. Embodiments exhibit improved optical properties.
