The present invention relates to a sealant for liquid crystals having extremely low contamination nature to a liquid crystal, excellent coatability and bondability to a substrate, long service life and pot life and high adhesive strength. A sealant for liquid crystals of the present invention is characterized by comprising (a) an epoxy resin represented by general formula (1):
(wherein a represents an integer of 2 to 4; n represents 0 to 3 (average value); R represents a divalent hydrocarbon group of 2 to 6 carbon atoms; A represents a polyvalent aromatic group; and G represents a glycidyl group, provided that when n is 0, (a) an epoxy resin represented by general formula (1) is a bisphenol S-type.), (b) a thermo-curing agent, (c) and a filler having average particle diameter of not larger than 3 μm.
本发明涉及一种密封剂,用于液晶,具有极低的对液晶的污染性,对基底具有优异的涂覆性和粘结性,具有长久的使用寿命和潜伏期,以及高粘接强度。本发明的液晶密封剂的特点在于包括(a)由通式(1)表示的环氧树脂:(其中a表示2到4的整数;n表示0到3(平均值);R表示2到6个碳原子的二价碳氢基团;A表示多价芳香基团;G表示环氧基团,但当n为0时,(a)由通式(1)表示的环氧树脂为双酚S型);(b)热固化剂;(c)和平均粒径不大于3μm的填料。
