Organic electroluminescent device and production process thereof

The invention relates to the technical field of semiconductors, in particular to an organic light-emitting device and a production process thereof, and the organic light-emitting device comprises a substrate, a thin film transistor layer, a light-emitting unit, a first packaging layer and a second packaging layer; the thin film transistor layer is arranged above the top surface of the substrate; the light-emitting unit is arranged above the top surface of the thin film transistor layer; the first packaging layer is formed above the top surface of the thin film transistor layer, so that the light-emitting unit is embedded in the first packaging layer, and the effects of filling the defect and smoothing the structure are achieved. The second encapsulation layer is formed above the top surface of the first encapsulation layer, plays a role in preventing water vapor and oxygen, and has excellent corrosion resistance. The first packaging layer and the second packaging layer are matched to replace a traditional OLE
