Abstract:
An improved one-drop-filling process of producing a liquid crystal display having a liquid crystal layer between a first substrate and a second substrate, comprises steps of applying a thermally curable resin composition on a sealing region at a periphery of a surface of the first substrate; conducting a first thermal curing of the thermally curable resin composition at a temperature of 40℃ to 75℃, and obtaining a partially cured product; dropping liquid crystal on a central area encircled by the sealing region of the surface of the first substrate or the corresponding area of the second substrate, and forming the liquid crystal layer; overlaying the second substrate on the first substrate; and conducting a second thermal curing of the partially cured product.

Abstract:
A cationically curable sealant composition for liquid crystal sealing is suitable to be used in one drop filling (ODF) process for manufacturing liquid crystal display device without the concern of moisture resistance and liquid crystal penetration. The cationically curable sealant composition comprises an epoxy resin selected from phenol novolac epoxy resin, dicyclopentadiene type epoxy resin, and combination thereof; and a diaryliodonium fluorine photoinitiator represented by formula (1), wherein R 1 and R 2 represent each independently hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted alkoxy, or carboxyl or its ester, M represents As, P, Sb or B, X represents F or C 6 F 5 , and n is 4 or 6. In addition, a process of producing a liquid crystal display having a liquid crystal layer between a first substrate and a second substrate, comprises steps of: applying a cationically curable sealant composition on a sealing region at a periphery of a surface of the first substrate; radiation curing the composition, and obtaining a partially cured product; dropping liquid crystal on a central area encircled by the sealing region of the surface of the first substrate or the corresponding area of the second substrate, and forming the liquid crystal layer; overlaying the second substrate on the first substrate; and radiation curing the partially cured product.
