An Organic light emitting display device, which may maximize aperture ratio of a pixel while also reducing the perception of a dark spot when a sub-pixel is partially short-circuited. The organic light emitting display device includes a plurality of pixels having sub-pixels. Some of the sub-pixels may have a thin organic emission layer which makes them likely to short-circuit across the thin organic emission layer. These sub-pixels are formed as divided sub-pixels including at least two drive transistors and operate such that even if one part of the divided sub-pixel has a short circuit, the other part will continue to emit light. Accordingly, while luminance is reduced as a result of short circuiting, a completely dark spot will not appear in the place of the pixel including the short circuit.
