Abstract: The present disclosure relates to an organic light emitting display device. According to an aspect of the present disclosure, an organic light emitting display device includes a plurality of sub-pixels including a first sub-pixel, a second sub-pixel and a third sub-pixel, a first electrode, a horizontal bank including a first horizontal bank and a second horizontal bank that are alternately arranged in a first direction to cover edges of the first electrodes, a vertical bank including a first vertical bank, a second vertical bank, and a third vertical bank that are alternately arranged in a second direction to cover edges of the first electrode and disposed on the horizontal bank, an organic light emitting layer and a second electrode. Wherein an area wider than the first sub-pixel is formed on the first horizontal bank or the second horizontal bank adjacent to the first sub-pixel, and ink is injected on the area, whereby color mixing of the ink can be minimized. And, a high-resolution organic light emitting display device can be implemented, simultaneously with improving display quality of the organic light emitting display device.
