The present invention relates to a getter composition and to an organic EL display device comprising same. More specifically, the present invention relates to: a getter composition comprising a hygroscopic agent and a silicone copolymer having one or more functional group selected from the group consisting of the carboxylic acid group and the polyalkylene oxide group; and a display device comprising same. La présente invention concerne une composition de piégeage (effet « getter ») et un dispositif d'affichage électroluminescent organique la comprenant. Plus spécifiquement, la présente invention concerne : une composition de piégeage comprenant un agent hygroscopique et un copolymère de silicone ayant un ou plusieurs groupes fonctionnels choisis parmi un groupe acide carboxylique et un groupe poly(oxyde d'alkylène). L'invention concerne également un dispositif comprenant cette composition.
