1. A method for assembling liquid crystal cells having a thin, uniform cell gap, comprising the steps of:

  • diluting a photo-definable polymeric resin with a solvent;

    applying the diluted photo-definable polymeric resin on a substrate;

    patterning the diluted photo-definable polymeric resin by selective exposure to a light; and

    selectively removing portions of the diluted photo-definable polymeric resin that were not exposed to the light, resulting in a viscous, uncured resin pattern that will maintain its physical structure during thermal curing, and that is adapted to serve as a spacer, an edge seal and an adhesive upon thermal curing.
