1. An organic electroluminescent display device, comprising: a rear substrate;an organic electroluminescent portion disposed on a surface of the rear substrate, the organic electroluminescent portion comprising a first electrode, an organic layer, and a second electrode;a front substrate opposing the rear substrate and coupled to the rear substrate to seal an internal space therebetween in which the organic electroluminescent portion is accommodated, thereby isolating the organic electroluminescent portion from the outside;a transparent moisture-absorbing layer disposed on substantially an entire internal surface of the front substrate; anda sealant disposed between the rear substrate and the transparent moisture-absorbing layer and in contact with the transparent moisture-absorbing layer to couple the front substrate and the rear substrate. 2. The organic electroluminescent display device of claim 1, wherein the transparent moisture-absorbing layer comprises absorption holes. 3. The organic electroluminescent display device of claim 2, wherein each of the absorption holes has a diameter in a range of about 0.5 nm to about 100 nm. 4. The organic electroluminescent display device of claim 2, wherein the transparent moisture-absorbing layer has a thickness range of about 100 nm to about 50 μm. 5. The organic electroluminescent display device of claim 4, wherein each of the absorption holes has a diameter in a range of about 0.5 nm to about 100 nm. 6. The organic electroluminescent display device of claim 1, wherein: the first electrode of the organic electroluminescent portion comprises a transparent electrode; andthe second electrode of the organic electroluminescent portion comprises a reflection-type electrode. 7. The organic electroluminescent display device of claim 1, wherein: the first electrode of the organic electroluminescent portion comprises a reflection-type electrode; andthe second electrode of the organic electroluminescent portion comprises a transparent electrode. 8. The organic electroluminescent display device of claim 1, wherein an inorganic protection layer is disposed on the second electrode. 9. The organic electroluminescent display device of claim 8, wherein the inorganic protection layer comprises one of a metal oxide and a metal nitride. 10. The organic electroluminescent display device of claim 1, wherein the internal space defined by the front substrate and the rear substrate is configured to be vacuous. 11. The organic electroluminescent display device of claim 1, wherein the internal space defined by the front substrate and the rear substrate is configured to be filled with an inert gas. 12. The organic electroluminescent display device of claim 1, wherein the front substrate comprises one of a glass substrate and a transparent plastic substrate. 13. The organic electroluminescent display device of claim 12, wherein a protection layer for protecting the front substrate from moisture is disposed on one of the internal surface and an outer surface of the front substrate. 14. The organic electroluminescent display device of claim 1, wherein the transparent moisture-absorbing layer is coated on the front substrate.
