Abstract
A technique comprising: providing on an outer side of a support film of a liquid crystal cell one or more first components having an oxygen transmission rate (OTR) at least 100,000 times lower than said support film of the liquid crystal cell; wherein the method further comprises interposing a preprepared oxygen-permeable adhesive film between said support film of the liquid crystal cell and an innermost one of said one or more first components; wherein the pre-prepared oxygen-permeable adhesive film has a thickness greater than another adhesive film provided on said outer side of said support film outside of said innermost one of said one or more first components.
