Kind Code:
A1
Abstract:
Provided is a composition that is for sealing an organic light-emitting element and that has good "wetness spreading property" which is the rate of reduction of the contact angle (θ) of a droplet with respect to the surface of an inorganic material when the droplet is dropped onto the inorganic material under predetermined conditions. The composition for sealing an organic light-emitting element according to the present disclosure contains a polymerization initiator and a polymerizable compound including, in the structure thereof, a carbon-carbon double bond and a fluorine atom (preferably, a trifluoromethyl group). The polymerizable compound particularly preferably includes in the structure thereof a group represented by formula (1) or a group represented by formula (2). [Chem. 41] (In the formula, a dashed line represents a dangling bond.)
