說(shuō)明書
The first capping layer 210 and the second capping layer 220 may increase external luminescence efficiency according to the principle of constructive interference.
The first capping layer 210 and the second capping layer 220 may each independently be an organic capping layer including an organic material, an inorganic capping layer including an inorganic material, or a composite capping layer including an organic material and an inorganic material. The organic capping layer may include polyethyleneterephthalate, polyethylenenaphthalate, polycarbonate, polyimide, polyethylenesulfonate, polyoxymethylene, polyarylate, hexamethyldisiloxane, acryl-based resin (for example, polymethylmethacrylate, polyacrylic acid, or the like), or a combination thereof.
At least one selected from the first capping layer 210 and the second capping layer 220 may each independently include at least one material selected from carbocyclic compounds, heterocyclic compounds, amine-based compounds, porphyrine derivatives, phthalocyanine derivatives, a naphthalocyanine derivatives, alkali metal complexes, and alkaline earth-based complexes. The carbocyclic compound, the heterocyclic compound, and the amine-based compound may be optionally substituted with a substituent containing at least one element selected from O, N, S, Se, Si, F, Cl, Br, and I. In an example embodiment, at least one selected from the first capping layer 210 and the second capping layer 220 may each independently include an amine-based compound.
In an example embodiment, at least one selected from the first capping layer 210 and the second capping layer 220 may each independently include the compound represented by Formula 201 or the compound represented by Formula 202.
