Abstract: An OLED device is disclosed. The device includes a substrate defined to have a first active area and a dummy area. First electrodes are formed on the substrate, and a first bank pattern is formed to overlap with edges of each first electrode and to expose a part of an upper surface of each first electrode. A second bank pattern is formed on the first bank pattern within the first active area, and a third bank pattern is formed on the first bank pattern within the dummy area in the same layer as the second bank pattern. The second bank pattern is formed to have a larger width than that of the third bank pattern. As such, an organic emission layer can be evenly formed in the active area.
