Abstract: An organic light emitting display (OLED) device is disclosed. The OLED device includes a substrate configured to include a sub-pixel defined into an emission region and a driving region. A first bank pattern configured to define the emission region of the sub-pixel is formed on the substrate. A second bank pattern configured to include an opening, which exposes the emission region and a part of the driving region, is formed on a part of an upper surface of the first bank pattern. An organic emission layer is formed in the opening. As such, the occupied area of the organic emission layer becomes wider. Therefore, the thickness deviation of the organic emission layer is prevented or minimized.

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.
