Abstract
(EN)
The objective of the present invention is to provide a sealant for organic EL display elements that has excellent sealing performance even when the application shape thereof is made into a thin line. The present invention is a sealant for organic EL display elements that contains a curable resin, and a polymerization initiator and/or thermosetting agent. The curable resin includes a compound having a (meth)acryloyl group and an adamantyl skeleton.

L'objectif de la présente invention est de fournir un agent d'étanchéité pour des éléments d'affichage EL organiques qui présente d'excellentes performances d'étanchéité même lorsque la forme d'application de celui-ci est réalisée en une ligne mince. La présente invention concerne un matériau d'étanchéité pour des éléments d'affichage EL organiques qui contient une résine durcissable, et un initiateur de polymérisation et/ou un agent thermodurcissable. La résine durcissable comprend un composé ayant un groupe (méth)acryloyle et un squelette adamantyle.
