ABSTRACT:
Substrate elements for making liquid crystal display devices are disclosed as well as display devices using such elements. The substrate elements are polymeric sheets which include spacing elements physically and chemically integral with the substrate so that when mated with a second substrate element, a precise, uniform spacing can be maintained between substrates. This allows large area displays to be fabricated which will provide uniform display properties throughout the display area.
