Disclosed are an organic light emitting display and a fabricating method of the same, which improve impact resistance and sealing property of a device using a reinforcing member besides a sealant. A first substrate includes a pixel region and a non-pixel region, at least one organic light emitting diode is formed at the pixel region and has a first electrode, an organic layer, and a second electrode, and the non-pixel region is formed at a peripheral portion of the pixel region. A second substrate is bonded to one region of the first substrate having the pixel region. A frit is disposed between the non-pixel region of the first substrate and the second substrate for adhering the first and second substrates to each other. An adhesive being coated to be spaced along a peripheral region of the frit, and including at least two discontinuous portions. A reinforcing member is disposed between the frit and the adhesive.

An organic light emitting display (OLED) device, comprising: a first substrate; a second substrate placed over the first substrate, wherein each of the first and second substrates is made of a single layer or comprises a plurality of layers; an array of organic light-emitting pixels interposed between the first and second substrates; and a sealing structure interposed between the first and second substrates while surrounding the array, wherein the sealing structure, the first substrate and the second substrate in combination define an enclosed space in which the array is located; wherein the sealing structure comprises a first member, a second member and a third member, the first member comprising a first material, the second member comprising a second material, and the third member comprising a third material, wherein the first member forms a closed loop surrounding the array, wherein the third member substantially surrounds the first member while having at least one discontinuous portion, and wherein the second member is formed by injecting a precursor of the second material through the discontinuous portion, and by subsequently curing the precursor to form the second material between the first and third members. 2. The device of claim 1, wherein the second member forms a closed loop surrounding the first member. 3. The device of claim 1, wherein the third member comprises at least two discontinuous portions. 4. The device of claim 1, wherein the at least one discontinuous portion comprises a gap or a material other than the third material. 5. The device of claim 1, wherein the first material comprises frit. 6. The device of claim 1, wherein the second material is the same as the third material. 7. The device of claim 6, wherein there is an identifiable interface between the second and third members. 8. The device of claim 1, wherein the second material is different from the third material. 9. The device of claim 1, wherein the second material comprises one or more selected from the group consisting of epoxy, acryl, and urethane resin. 10. The device of claim 1, wherein the third material comprises one or more selected from the group consisting of epoxy, acrylate, urethane acrylate, and acrylate cyanide resin. 11. The device of claim 1, wherein the first member 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. 12. A method of making an organic light emitting display (OLED) device, the method comprising: providing an intermediate device comprising: a first substrate; a second substrate placed over the first substrate; an array of organic light-emitting pixels interposed between the first and second substrates; and a first sealing member interposed between the first and second substrates while substantially surrounding the array, a third sealing member having at least one discontinuous portion and interposed between the first and second substrates while substantially surrounding the first sealing member with a space defined between the first and third sealing members and further between the first and second substrates; and subsequently filling a material into the space defined between the first and third sealing members of the intermediate device through the discontinuous portion so as to form a second sealing member interposed between the first and second substrates and further between the first and third sealing members. 13. The method of claim 12, wherein the third sealing member comprises at least one discontinuous portion while substantially surrounding the first sealing member. 14. The method of claim 13, wherein filling comprises injecting the material into the space via the at least one discontinuous portion. 15. The method of claim 14, wherein filling further comprises moving the material within the space. 16. The method of claim 15, wherein moving the material within the space uses positive or negative air pressure. 17. The method of claim 12, wherein the third sealing member comprises a portion generally parallel to a portion of the first sealing member. 18. The method of claim 12, further comprising curing the material after filling into the space. 19. The method of claim 12, wherein the first sealing member comprises fit and forms a closed loop surrounding the array. 20. The method of claim 12, wherein the second sealing member and third sealing member comprises substantially the same material. 21. The method of claim 12, wherein providing the device comprises: providing the second substrate, the first sealing member formed on the second substrate and the third sealing member formed on the second substrate; and arranging the first and second substrates such that the array is interposed between the first and second substrates and that the array is surrounded by the first sealing member. 22. The method of claim 12, wherein providing the device comprises: providing the first substrate and the first sealing member formed on the first substrate; and forming the third sealing member substantially parallel to the first sealing member with a gap therebetween; and arranging the first and second substrates such that the array is interposed between the first and second substrates and that the array is surrounded by the first sealing member. 23.
