    • A resin composition for sealing liquid crystal cells comprising as principal ingredients epoxy resin containing a polysulfide modified epoxy resin, hydrazide compounds and fillers.The said epoxy resin contains a polysulfide modified epoxy resin expressed in an amount of the general formula (1) by 20 to 100% by weight in the entire epoxy resin and the average molecular weight of the entire epoxy resin is between 300 and 3000 Formula (1) is defined as follows: ##STR1## where each of R.sup.1 and R.sub.3 represents at least one organic group selected from a group consisting of bisphenol structures, aliphatic oxyether structures and aliphatic thioether structures and R.sup.2 represents a polysulfide structure expressed by --(C.sub.2 H.sub.4 OCH.sub.2 OC.sub.2 H.sub.4 S.sub.m).sub.n --, wherein m represents the number of sulfur atoms contained in a polysulfide structure, which is 1 or 2, and n represents the average number of polysulfide structures contained in the above formula, which is between 1 and 50.A film-made liquid crystal cell made by using the resin composition is excellent in adhesion, flexibility, electric properties and has high reliability.
    • 一种用于密封液晶单元的树脂组合物,其包含含有多硫化物改性环氧树脂,酰肼化合物和填料的作为主要成分的环氧树脂。 所述环氧树脂包含在整个环氧树脂中以通式(1)的量表示20至100重量%的多硫化物改性环氧树脂,并且整个环氧树脂的平均分子量为300至3000(式 1)定义如下:其中R1和R3各自表示选自双酚结构,脂族氧醚结构和脂族硫醚结构中的至少一种有机基团,并且R 2表示由下式表示的多硫结构: (C2H4OCH2OC2H4Sm)n-,其中m表示多硫化物结构中所含的硫原子数,为1或2,n表示上式中所含的多硫化物结构的平均数,介于1和50之间。 通过使用该树脂组合物制成的液晶单元具有优异的粘合性,柔韧性,电性能,并具有高可靠性。
