A sealant for liquid crystals which comprises an epoxy resin represented by the following formula (1): [Chemical formula 1] (wherein n, indicating the average degree of polymerization, is a positive number of 0 to 5) as a resin ingredient, a hardener, a hardening accelerator, and an inorganic filler. When used for producing a liquid-crystal display, the sealant for liquid crystals shows excellent suitability for screen printing. The liquid-crystal display thus produced can have excellent reliability concerning moisture resistance. La présente invention concerne un agent d'étanchéité pour cristaux liquides, qui comprend: comme composante de résine, une résine époxyde représentée par la formule (1) dans laquelle n représente le degré moyen de polymérisation et est un nombre positif de 0 à 5; un agent durcissant; un accélérateur de durcissement; et une charge minérale. Lorsqu'il est utilisé pour la production d'un affichage à cristaux liquides, l'agent d'étanchéité pour cristaux liquides convient particulièrement bien à la sérigraphie. L'affichage à cristaux liquides ainsi produit peut être d'excellente fiabilité en ce qui concerne la résistance à l'humidité.
