First Claim
1. An organic electroluminescent device, comprising:
- a rear substrate;
an organic electroluminescent unit arranged on one surface of the rear substrate, wherein the organic electroluminescent unit includes a first electrode, an organic film, and a second electrode; and
a front substrate coupled with the rear substrate, wherein the front substrate includes an uncovered non-resin porous oxide layer arranged directly on an inner surface of the front substrate, the uncovered non-resin porous oxide layer adhering itself directly to the inner surface of the front substrate,wherein the porous oxide layer is formed of a material selected from the group consisting of;
hydrated amorphous alumina, and one or more compound selected from the group consisting of metal halide, metal sulfate, and metal perchlorate; and
hydrated amorphous alumina, silica, and one or more compound selected from the group consisting of metal halide, metal sulfate, and metal perchlorate, andwherein the alumina is boehmite or bayerite.

Abstract
Provided are an organic electroluminescent device and a method of manufacturing the same. An organic electroluminescent device, comprising a rear substrate, an organic electroluminescent unit formed on one surface of the rear substrate and having a first electrode, an organic film, and a second electrode, and a front substrate joined to the rear substrate and having a porous oxide layer based on alumina on an inner surface of the front substrate. The alumina is hydrated amorphous alumina. The porous oxide layer is composed of hydrated amorphous alumina; hydrated amorphous alumina and silica; hydrated amorphous alumina, and one or more selected from alkaline metal oxide, alkaline earth metal oxide, metal halide, metal sulfate, and metal perchlorate, which are captured in a network of the alumina; or hydrated amorphous alumina, silica, and one or more selected from alkaline metal oxide, alkaline earth metal oxide, metal halide, metal sulfate, and metal perchlorate, which are captured in a network of the alumina and a network of the silica. The organic electroluminescent device may be used as a front emission type, a rear emission type, or a both-direction emission type display.
