It is an object of the invention to provide a curing resin composition that scarcely causes pollution of a liquid crystal owing to elution of its components to the liquid crystal material and therefore, causes little unevenness of color in liquid crystal display in the case of using it as a sealant for a liquid crystal display element or an end-sealing material for a liquid crystal display element in fabrication of a liquid crystal display element and that is excellent in the storage stability and therefore, optimum for fabrication of a display apparatus especially by one drop fill process and to provide a sealant for a display element and an end-sealing material for a display element using the composition.
The invention provides a curing resin composition to be used for a sealant or an end-sealing material for a display element, which comprises a curing resin together with a photopolymerization initiator and/or a curing agent and, has a carbonyl group derived from a (meth)acryl group together with an epoxy group and/or a hydroxyl group derived from an epoxy group and, a cured product of which has nitrogen atoms at a ratio of 3 to 10% by atom in the total of carbon atoms, hydrogen atoms and nitrogen atoms in the composition; a volume resistance of 1×10

Ω·cm or higher; a dielectric constant of 3 or higher at 100 kHz; and a glass transition temperature of 80 to 150° C.
本发明的目的是提供一种固化树脂组合物,该组合物由于其成分向液晶材料渗出而几乎不会污染液晶,因此在将其用作液晶显示元件的密封剂或液晶显示元件的端部密封材料时,液晶显示中很少出现颜色不均匀,并且在储存稳定性方面表现出色优异,因此特别适用于通过一滴填充工艺制造显示装置,并提供使用该组合物的显示元件的密封剂和端部密封材料。本发明提供了一种用于显示元件的密封剂或端部密封材料的固化树脂组合物,该组合物包括固化树脂、光聚合引发剂和/或固化剂,具有由(甲基)丙烯酰基派生的羰基基团以及由环氧基派生的环氧基和/或羟基基团,其固化产物在碳原子、氢原子和氮原子的总和中的氮原子比例为3至10%的原子;体积电阻率为1×1013Ω·cm或更高;在100 kHz时具有3或更高的介电常数;和玻璃化转变温度为80至150℃。
