Patent ID: 8198624

Claim:
An organic light emitting device comprising: a substrate; a display that is positioned on the substrate and includes a plurality of subpixels each including a first electrode, an emissive unit including at least an organic emissive layer, and a second electrode; dummy patterns that surround the subpixels, and include dummy layers including the same material as that of at least one of a plurality of layers for forming the emissive unit; and a sealing area that is positioned at edges of the display and the dummy patterns, and is coated with a sealant, wherein the dummy patterns are positioned between the display and the sealing area, and are positioned closer to the sealing area than the display, wherein the dummy patterns prevent the subpixels from moisture penetrating the sealing area by absorbing the moisture, and wherein each of the dummy patterns further includes a metal layer positioned on the dummy layer, and the metal layer includes the same formation material as that of the second electrode to prevent the peeling of the dummy layer absorbing the moisture.
