[Problems] To provide a liquid crystal sealing material having an extremely low possibility of contaminating liquid crystals and a high bond strength.
[Means For Solving Problems] A liquid crystal sealing material comprising:
(a) a resin obtained by (meth)acryloylating an epoxy resin (A) represented by formula (1);
(b) a photopolymerization initiator; and
(c) an inorganic filler having a mean particle diameter of 3 μm or less, wherein a ratio of a p,p′ isomer in a bisphenol F monomer unit constituting the epoxy resin (A) accounts for 40% or more,
(wherein a repeating unit number z is in a range of 0 to 2).
