PROBLEM TO BE SOLVED: To provide a liquid crystal sealant for a liquid crystal dropping technique that has a high adhesive strength to an alignment film, particularly an optical alignment film, is excellent in low liquid crystal contamination property and humidity resistance, and achieves high definition, high luminance, frame width reduction, high-speed response, low-voltage driving, and long life of a liquid crystal display device.SOLUTION: There is provided a liquid crystal sealant for a liquid crystal dropping technique containing (A) an epoxy compound represented by the following formula (1) and (B) a thermal radical polymerization initiator. In the formula, n represents the average degree of polymerization; R independently a hydrogen atom or a methyl group; X a hydrogen atom or an epoxy group.SELECTED DRAWING: None 【課題】配向膜、特に光配向膜への接着強度が高く、低液晶汚染性や耐湿性等も優れ、液晶表示素子の高精細化、高輝度化、狭額縁化、高速応答化、低電圧駆動化、長寿命化を実現する液晶滴下工法用液晶シール剤を提供する。【解決手段】（Ａ）下記式（１）で表されるエポキシ化合物、及び（Ｂ）熱ラジカル重合開始剤、を含有する液晶滴下工法用液晶シール剤。（式中ｎは平均重合度を表し、Ｒは独立に水素原子またはメチル基を表し、Ｘは水素原子またはエポキシ基を表す）【選択図】なし
