ABSTRACT:
The present invention is directed to a thin film material for encapsulation of organic or polymeric light-emitting electric device having light-emitting layer between cathode and anode, for elongation of lifetime of said device and for providing said device with flexibility, more specifically, to a thin film material for encapsulation of organic or polymeric light-emitting electric device comprising polymer having, as repeating unit of backbone, homo-, 2-component co-, ter-, or tetra-polymer of one to four pentaerythritol acrylate monomer, or physically mixed polymer blend of said polymer and polymers other than poly(pentaerythrithol acrylate).Moreover, the present invention is directed to a method for encapsulation of organic or polymeric light-emitting device using said thin film material consisting of wet and dry process.The light-emitting device encapsulated according to the present invention can be bended and can be used in the manufacturing of large surface area display.
