Procedure

A bisphenol F-type epoxy resin (RE-404P, manufactured by Nippon Kayaku Co., Ltd., epoxy equivalent: 160 g/eq, hydrolyzed amount: 30 ppm) was reacted with acrylic acid of amount of 100% equivalent to epoxy groups, subjected to purification by liquid-separation treatment using ion exchanged water/toluene and then deprived of toluene by evaporation to obtain an acrylate of the bisphenol F-type epoxy resin. Thus obtained acrylate of the bisphenol F-type epoxy resin of 80 parts by weight, the Epoxy resin D (EBPS-300, manufactured by Nippon Kayaku Co., Ltd.) used in the Experiment Example of 20 parts by weight, 3,6-bis(2-methyl-2-morphorinopropionyl)-9-n-octyl carbazole (Adeka Optmer N-1414, manufactured by Asahi Denka Kogyo Co., Ltd.) of 1.8 parts by weight, serving as a radical-forming photopolymerization initiator and an amino silane coupling agent (N-β(aminoethyl)-γ-aminopropyltrimethoxy silane, KBM-603, manufactured by Shin-Etsu Silicone Co., Ltd.) of 1.2 parts by weight were heated and dissolved at 90° C. to obtain a resin solution. Thus obtained resin solution was cooled to room temperature, then added with 4.2 parts by weight of isophthalic acid dihydrazide (trade name: IDH-S; prepared by finely grinding a material of jet-mill ground-grade manufactured by Otsuka Chemical Co., Ltd. using a jet mill; melting point: 224° C.; active hydrogen equivalent: 48.5 g/eq; average particle diameter: 1.7 μm; maximum particle diameter: 7 μm), 30 parts by weight of fused ground silica (Crystalite 1FF, manufactured by Tatsumori Co., Ltd., average particle diameter: 1.0 μm) and 1 part by weight of IXE-100 (a zirconium phosphate-series ion scavenger, manufactured by Toa Gosei Co., Ltd.), and kneaded using a three-roll mill to obtain a sealant for liquid crystals of the present invention. The sealant had viscosity of 480 Pa·s (25° C.) (measured by an R-type viscometer, manufactured by Toki Sangyo Co., Ltd.).
