PROBLEM TO BE SOLVED: To provide a liquid crystal sealant that has an excellent resistance to the insertion of liquid crystal into the liquid crystal sealant, suppresses the generation of gelation even in the use for a screw type dispenser, which leads to excellence in workability, and has an excellent general property as liquid crystal sealant such as adhesive strength.SOLUTION: A liquid crystal sealant for a liquid crystal dropping method contains a curable resin having a viscosity at 25°C and 1 rpm of 500 Pa s or more and 2000 Pa s or less, which is measured by using a type E viscometer, and having (A) radical polymerization inhibitor and (B) a (meth)acryloyl group. 【課題】液晶の液晶シール剤への差込耐性に優れ、更にスクリュー式ディスペンサーでの使用においてもゲル化を引き起こし難い為、作業性においても優れ、また接着強度等の液晶シール剤としての一般特性にも優れる液晶シール剤を提供すること。【解決手段】Ｅ型粘度計を用いて測定した２５℃、１ｒｐｍにおける粘度が、５００Ｐａ・ｓ以上２０００Ｐａ・ｓ以下であり、（Ａ）ラジカル重合防止剤、（Ｂ）（メタ）アクリロイル基を有する硬化性樹脂を含有する液晶滴下工法用液晶シール剤。【選択図】なし
