Abstract
Abstract A liquid crystal display device including two electrically insulating substrates, electrodes on the inner surfaces of the substrates, a film of liquid crystal material contained between the electrodes and a resinous material as sealant and/or encapsulant and/or inner structural component characterised in that the resinous material is the product of light-curing a light-curable resin composition comprising at least one compound having two or more non-aromatic carbon-carbon unsaturated bonds per molecule, at least one compound having two or more mercapto groups per molecule and a photoinitiator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
84 words
A liquid crystal display device including two electrically insulating substrates, electrodes on the inner surfaces of the substrates, a film of liquid crystal material contained between the electrodes and a resinous material as sealant, encapsulant or inner structural component characterised in that the resinous material is the product of light-curing a light-curable resin composition comprising at least one compound having two or more non-aromatic carbon-carbon unsaturated bonds per molecule, at least one compound having two or more mercapto groups per molecule and a photoinitiator.
Claim 2
Dependent Claim
84 words
A liquid crystal display device including two electrically insulating substrates, electrodes on the inner surfaces of the substrates, a film of liquid crystal material contained between the electrodes and a resinous material as sealant, encapsulant or inner structural component characterised in that the resinous material is the product of light-curing a light-curable resin composition comprising at least one compound having two or more non-aromatic carbon-carbon unsaturated bonds per molecule, at least one compound having two or more mercapto groups per molecule and a photoinitiator.
Claim 3
Dependent Claim
15 words
A device according to claim 1 wherein the photoinitiator is a visible light sensitive photoinitiator.
Claim 4
Dependent Claim
26 words
