Abstract:
A method of manufacturing a liquid crystal display, comprising the steps of:(a) positioning a first substrate layer having inner and outer surfaces to overlay an opposing second substrate layer having inner and outer surfaces such that the first and second substrate layer inner surfaces face each other, each of the inner surfaces having a perimeter portion therearound;(b) applying a first sealant to at least one of the perimeter portions of said first and second substrate layers such that the sealant forms an injection opening along the perimeter portion;(c) compressing the outer surfaces of said first and second substrates after said applying step at a first pressure to structurally attach said sealant and substrates together such that they define a cell cavity therebetween;(d) injecting a liquid crystal material through the injection opening into the cell cavity at a pressure sufficient to expand the cell such that the first and second substrate layers take a non-planar configuration;(e) compressing the first and second substrate layers to a substantially planar configuration thereby expelling a residual amount of the injected liquid crystal material from the cell cavity out of the injection opening;(f) applying a second sealant proximate to the injection opening to position sealant material for an end seal thereat; and(g) compressing said first and second substrates at a second pressure during step (e) greater than the first pressure of step (c).
