Patent ID: 7955717

Claim:
An organic electroluminescent device, comprising: a substrate; an organic electroluminescent unit formed on the substrate, the organic electroluminescent unit comprising a first electrode, a second electrode and an organic luminescent unit interposed between the first electrode and the second electrode; a sealant directly formed on the substrate; a sealing substrate covering the organic electroluminescent unit, the sealing substrate contacting the sealant; and a sealing layer formed on the sealing substrate, the sealing layer comprising a cohesion layer attached to the sealing substrate, a transparent polymer layer formed on the cohesion layer, and a transparent moisture absorption layer formed on the transparent polymer layer to absorb moisture in a sealed space formed by joining the sealing substrate with the substrate, the sealing layer preventing Rayleigh scattering, the transparent moisture absorption layer comprising nano-sized porous particles and pores, an average diameter of the pores being less than 100 nm, the pores being formed between the nano-sized porous particles.
