Abstract
This invention discloses laminates comprising dyed liquid crystalline polymer based polarizers in the middle with a non-peelable, non-liquid crystalline polymeric cover layers, prepared by a process of coextrusion. The laminates are suitable to prepare liquid crystal display devices therefrom. An illustrative laminate comprises a dyed liquid crystal polymer as the polarizing film with polyethylene terephthalate as the cover layers.
