Abstract:
1. A method of manufacturing an organic electroluminescence device, the method comprising: forming an encapsulating layer on an encapsulating substrate by coating the encapsulating substrate with an encapsulating layer-forming composition and thermally processing the coated encapsulating substrate; removing contaminants attached to a region of the encapsulating substrate by performing a plasma treatment on the region of the encapsulating substrate, with the plasma treated region of the encapsulating substrate being reserved to receive a sealant; applying the sealant to at least one of the plasma treated region of the plasma treated encapsulating substrate and a substrate on which an organic electroluminescent unit is deposited, the organic electroluminescent unit including a first electrode, an organic layer, and a second electrode, which are sequentially stacked; and combining the encapsulating substrate and the substrate on which the organic electroluminescent unit is deposited.
