Disclosed is an organic light-emitting display device in which the substrate and the encapsulation substrate are attached to each other by using a frit. The organic light-emitting display device includes a first substrate including a pixel region in which an organic light-emitting diode is formed, and a non-pixel region. The organic light-emitting diode includes an organic light-emitting layer between a first electrode and a second electrode. A second substrate attached to the first substrate. A frit is provided between the non-pixel region of the first substrate and the second substrate to attach the first substrate and the second substrate. A reinforcement material of resin is formed outside the frit.

1. An organic light-emitting display device, comprising: a first substrate, wherein the first substrate comprises glass;a second substrate placed over the first substrate, wherein the second substrate comprises glass;an array of organic light-emitting pixels interposed between the first and second substrates;a frit seal interposed between the first substrate and the second substrate while surrounding the array, wherein the frit seal, the first substrate and the second substrate in combination define a substantially enclosed space in which the array is located; anda structure interposed between the first and second substrates, wherein the structure is interposed only between the first and second substrates, wherein the structure contacts the frit seal along an entire outer perimeter of the frit seal to surround the frit seal, wherein the frit seal surrounds the array, and wherein the structure improves structural strength of the device and sealing of the enclosed space, wherein the structure comprises a polymeric resin. 2. The device of claim 1, wherein the portion of the structure contacts the frit seal. 3. The device of claim 1, wherein the structure comprises at least one selected from the group consisting of cyanoacrylate, acrylate, epoxy, acrylate, urethane acrylate and cured polymers of two or more of the foregoing. 4. The device of claim 1, wherein the frit seal is connected to the first substrate via a material formed between the frit seal and the first substrate. 5. The device of claim 1, wherein the structure contacts the first substrate. 6. The device of claim 1, wherein the structure is connected to the first substrate via another material between the structure and the first substrate. 7. The device of claim 1, wherein the first substrate comprises a first edge and the second substrate comprises a second edge extending generally along the first edge, and wherein the frit seal extends along the first and second edge while apart from the first and second edges, wherein the structure contacts the first and second substrates and extends along the first and second edges. 8. The device of claim 7, wherein the structure continuously contacts the first and second edges. 9. The device of claim 1, wherein the first substrate comprises a first edge and the frit seal is apart from the first edge from about 0.3 to about 0.7 mm. 10. The device of claim 1, wherein the first substrate comprises a front surface of the device, the front surface facing away from the second substrate, and wherein the structure provides a side surface of the device. 11. The device of claim 10, wherein the first substrate comprises a first edge and the second substrate comprises a second edge extending generally along the first edge and wherein the side surface extends continuously along the first and second edges and is substantially planar. 12. The device of claim 1, wherein the frit seal comprises one or more materials selected from the group consisting of magnesium oxide (MgO), calcium oxide (CaO), barium oxide (BaO), lithium oxide (Li2O), sodium oxide (Na2O), potassium oxide (K2O), boron oxide (B2O3), vanadium oxide (V2O5), zinc oxide (ZnO), tellurium oxide (TeO2), aluminum oxide (Al2O3), silicon dioxide (SiO2), lead oxide (PbO), tin oxide (SnO), phosphorous oxide (P2O5), ruthenium oxide (Ru2O), rubidium oxide (Rb2O), rhodium oxide (Rh2O), ferrite oxide (Fe2O3), copper oxide (CuO), titanium oxide (TiO2), tungsten oxide (WO3), bismuth oxide (Bi2O3), antimony oxide (Sb2O3), lead-borate glass, tin-phosphate glass, vanadate glass, and borosilicate.
