Abstract:
1. An organic electroluminescent device, comprising: a first substrate; an organic electroluminescent unit comprising a first electrode, an organic film, and a second electrode stacked on a surface of the first substrate; a second substrate joined to the first substrate, substantially sealing an internal space in which the organic electroluminescent unit is disposed; and a porous oxide layer comprising a porous silica and a metal compound arranged directly on an interior surface of the second substrate, the porous oxide layer adhering itself directly to the inner surface of the second substrate, and wherein the porous oxide layer has a thickness of about 0.1 to about 12 μm, wherein the metal compound of the porous oxide layer is one or more selected from the group consisting of alkaline metal oxide, alkaline earth metal oxide, metal halide, metal sulfate, and metal perchlorate, wherein the alkaline metal oxide comprises one or more material selected from the group consisting of lithium oxide (Li wherein the metal sulfate comprises one or more material selected from the group consisting of lithium sulfate (Li wherein the metal halide comprises one or more material selected from the group consisting of calcium chloride (CaCl wherein the metal perchlorate comprises one or more material selected from the group consisting of barium perchlorate (Ba(ClO wherein the metal compound of the porous oxide layer is confined in a network of the porous silica; and wherein the porous silica network comprises a silica frame and a plurality of absorption holes.
