UN DISPOSITIVO DE VISUALIZACION DE CRISTAL LIQUIDO QUE INCLUYE DOS SUSTRATOS ELECTRICAMENTE AISLADORES, ELECTRODOS EN LAS SUPERFICIES INTERIORES DE LOS SUSTRATOS, UNA PELICULA DE UNA MATERIAL DE CRISTAL LIQUIDO COLOCADA ENTRE LOS ELECTRODOS Y UNA MATERIAL RESINOSO COMO OBTURADOR Y/O ENCAPSULANTE Y/O COMPONENTE ESTRUCTURAL INTERIOR QUE SE CARACTERIZA PORQUE EL MATERIAL RESINOSO ES EL RESULTADO DE LA CURACION LUMINOSA DE UNA COMPOSICION DE RESINA QUE SE PUEDE CURAR CON LUZ QUE CONTIENE AL MENOS UN COMPUESTO QUE TIENE DOS O MAS ENLACES INSATURADOS CARBONOCARBONO NO AROMATICOS POR MOLECULA, AL MENOS UN COMPUESTO QUE TIENE DOS O MAS GRUPOS MERCAPTO POR MOLECULA Y UN FOTOINICIADOR. 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.
