Abstract:
A process for selectively removing a light modulating layer containing a liquid crystalline material in a polymeric binder from the electrically conductive layer of a liquid crystal display web, the process comprising:providing a liquid crystal display web comprising a flexible substrate, an electrically conducting layer disposed on the substrate, and a light modulating layer disposed on the electrically conductive layer, the light modulating layer including a liquid crystalline material dispersed in a polymeric binder and having an upper surface; transporting the web at a controlled rate of speed from a first station to a second station situated at a selected distance from the first station; at the first station, applying to a selected portion of the upper surface at a controlled rate of application a solvent effective for softening the light modulating layer, thereby forming a selected softened portion of the light modulating layer; and at the second station, selectively removing the selected softened portion of the light modulating layer from the electrically conductive layer of the substrate.
