摘要

PURPOSE: An organic light-emitting device which includes a sealing structure is provided to improve moisture and oxygen barrier effects by forming a sealing layer consisting of material more than 2 kinds.;CONSTITUTION: An organic light-emitting unit comprises a first electrode(2), an organic layer(3) which includes a light-emitting layer, and a second electrode(4). A sealing layer is included in the front side of the upper side of the organic light-emitting unit. The sealing layer comprises two and more among a moisture interception film(6), a glass cap(7), metal foil, and a conductive film. A sealant(10) is included in the side of the organic light-emitting unit. A buffer layer is formed between the second electrode and the sealing layer.;COPYRIGHT KIPO 2012
