Abstract
A sealing compound for use in production of a liquid crystal display unit, comprises isobornyl(meth)acrylate, epoxy acrylate, a photopolymerizable initiator, epoxy resin having one or more polymerizable groups in one molecule, a latent thermosetting agent obtained by pretreating imidazole compounds, adducts of imidazole compounds and carboxylate of imidazole compounds, and/or adducts of imidazole compounds and epoxy resin with isocyanate compounds. The sealing compound is applicable particularly for sealing liquid crystal in between substrates of the liquid crystal display unit, and can secure the electrode substrates without misregistration of the substrates and uneven separation of the substrates.
