A sealant for a one drop fill process is characterized by curing through two steps consisting of photocure using visible light from which 400 nm or shorter wavelengths are cut off and thermal cure and, when in contact with a liquid crystal composition, is less contaminating to the liquid crystal composition with a photo radical initiator, and exhibits high adhesive strength to a substrate. The sealant contains (1) a titanocene photo radical initiator, (2) a photocuring resin, (3) a latent epoxy curing agent and, if necessary, (4) a monomer having at least two glycidyl ether groups per molecule as a thermosetting resin. |
