Patent ID: 8563112

Claim:
An organic EL light-emitting device comprising: an element formation substrate on which an organic EL element including an organic light-emitting layer is formed; and a sealing substrate for sealing the organic EL element so as to accommodate the organic EL element between the sealing substrate and the element formation substrate, wherein an adhesive sealing portion is formed in the peripheral edge portion between the element formation substrate and the sealing substrate, and gel layer is accommodated in between the element formation substrate, on which the organic EL element surrounded by the sealing portion is formed, and the sealing substrate in such a state of adhering to the element formation substrate and the sealing substrate, and wherein the gel layer contains an oligomer or a polymer consisting of organosiloxane, representable by formula —R 1 R 2 SiO—, wherein R 1 and R 2 each independently represents a group selected from the group consisting of an alkyl group, an alkyl group with saturated substituent, an alkyl group with unsaturated substituent, a substituted phenyl group, an unsubstituted phenyl group, a fluoroalkyl group, a fluoroalkyl group with saturated substituent and a fluoroalkyl group with unsaturated substituent as a skeleton, or an oligomer or a polymer consisting of fluorinated polyether, representable by formula —CF 2 CFYO— wherein Y represents F or CF 3 as a skeleton and having a functional group containing Si at the terminal.
