Embodiment 1
[0101] 100g of the epoxy resin represented by formula (1) (RE-600NM, manufactured by Nippon Kayaku Co. Ltd., which contains 65-80wt% of the compound of formula (1) n=0) and 30g as a curing agent contains 30 ~50wt% of phenol novolac resin (PN-152, manufactured by Nippon Kayaku Co. Ltd.) having a bicyclic compound is heated and dissolved in 10g RHODIASOLVE RPDE (containing 57~63wt% dimethyl glutarate, 21~27wt) as a solvent % Dimethyl succinate, 12-20wt% dimethyl adipate, manufactured by Rhodia Nikka Co.). In the resulting resin solution, 60 g of spherical alumina (NANOTEC ALUMINA SP-C, manufactured by CI Kasei Co. Ltd., manufactured by CI Kasei Co. Ltd.) as an inorganic filler and 10 g as a coupling agent were mixed as an inorganic filler. N-phenyl-γ-aminopropyltrimethoxysilane, disperse them in the resin solution, and then add 8g of AMICURE MYH-K (amine adduct: Ajinomoto Fine Techno Co. Ltd. make), the liquid crystal sealing compound of this invention was obtained.
