Organic light emiting device and method of manufacturing the same

摘要

Disclosed is an organic light emitting device which includes a substrate (10); an encapsulation substrate (17), an organic light emitting unit (12) interposed between the substrate (10) and the encapsulation substrate (17). A water vapor absorption material-containing transparent sealant layer (16) covers the organic light emitting unit (12). The sealant layer includes a transparent sealant having a water vapor transmission rate (WVTR) of about 20 g/m 2 ·day or less and a water vapor absorption material having an average particle size of about 100 nm or less.
