Abstract:
A liquid crystal display panel comprising two transparent substrates with electrodes attached therebetween, the substrates sealed to each other with a seal material free of reactive epoxy groups, wherein said seal material undergoes a first process of irradiating an ultraviolet ray to the seal material, and a second process for increasing the curing by heating the seal material after the first process, and wherein the curing resin of the seal material is cured to have a curing ratio of 50% or more after said first process and a curing ratio of 80% or more after said second process, wherein the seal material is formed from (meth)acrylate monomers or oligomers derived from an epoxy compound, (meth)acrylic acid ester, a photoinitiator, a thermosetting agent and an inorganic filler, wherein the (meth)acrylic acid ester includes 5 to 10 weight % based on the seal material of (meth)acrylic acid ester having a plurality of (meth)acrylic acid residues per molecule and 2 to 10 weight % based on the seal material of (meth)acrylic acid ester having one (meth)acrylic acid residue per molecule, the seal material being capable of ultraviolet ray curing and thermosetting, wherein the seal material undergoes radical polymerization.
