PROBLEM TO BE SOLVED: To provide a liquid crystal sealant for one drop filling, to be cured by light and/or heat, configured to ensure extremely low corrosion property of wiring after humidity test and excellent general properties, such as low liquid crystal contamination property and adhesive strength, thereby achieving high definition, quick response, low-voltage drive, and extension of life.SOLUTION: A liquid crystal sealant for one drop filling contains (A) a curable compound and (B) an inorganic filler. (B) The inorganic filler is surface-treated with a compound represented by the following formula (1). In the formula (1), all Rare the same and represent a (C1-C4) alkyl group.SELECTED DRAWING: Figure 1 【課題】本発明は、光及び／又は熱によって硬化する液晶滴下工法用液晶シール剤に関するものであって、耐湿試験後の配線腐食性が極めて低く、また、低液晶汚染性や接着強度等の一般的特性においても優れる為、液晶表示素子の高精細化、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）硬化性化合物、及び（Ｂ）無機フィラーを含有し、前記（Ｂ）無機フィラーが下記式（１）で表される化合物で表面処理されていることを特徴とする液晶滴下工法用液晶シール剤。[前記式（１）中、Ｒ１は全て同じであり、（Ｃ１−Ｃ４）アルキル基を表す。]【選択図】図１
