  • Organic electroluminescent apparatus
    Patent number: 9013099
    Abstract: An organic electroluminescent apparatus including a substrate, an organic light-emitting device layer, a patterned structure layer and an encapsulation film is provided. The substrate has a light-emitting region and a non-light-emitting region. The organic light-emitting device layer is disposed on the substrate in the light-emitting region. The patterned structure layer is disposed on the substrate in the non-light-emitting region. The encapsulation film is disposed on the substrate and covers the organic light-emitting device layer and the patterned structure layer. A surface of the encapsulation film on the patterned structure layer is a concave-convex surface, and a surface of the encapsulation film on the organic light-emitting device layer is an even surface.
