Abstract
Official abstract text for this publication.
An object of the present invention is to provide a pre-edging lens and a method for manufacturing an edged lens, wherein provisions are made to be able to maintain the cell gap of a liquid crystal lens structure constant while, in effect, eliminating the need to incorporate any spacers in the edged lens. More specifically, the invention provides a pre-edging lens and a method for manufacturing an edged lens, wherein the pre-edging lens includes a first transparent substrate, a second transparent substrate, a first sealing material which does not contain any spacer, a liquid crystal layer provided between the first transparent substrate and the second transparent substrate and sealed by the first seal, and a second seal which contains a spacer and which is disposed in a region provided between the first transparent substrate and the second transparent substrate and located outwardly of the first seal, the region being removed during edging.
First claim
Opening claim text (preview).
What is claimed is: 1. An edged lens manufacturing method comprising the steps of: disposing, between a first transparent substrate and a second transparent substrate, a first sealing material which does not contain any spacer member and a second sealing material which contains a spacer member, said second sealing material being located outwardly of said first sealing material, and thereby forming a blank lens having a liquid crystal layer provided between said first transparent s…
