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.

Abstract: Provided is a white organic light emitting device (OLED), including: a first electrode formed on a substrate; a hole transport layer formed on the first electrode; an emission layer formed on the hole transport layer; an electron transport layer formed on the emission layer; and an color control layer formed on at least one of the hole transport layer, the emission layer and the electron transport layer, and emitting green and/or red by energy transfer from the emission layer. The white OLED emits red, green and blue light with high efficiency, has excellent color reproducibility and a high color reproduction index.
