Claim Text:
1. An organic light emitting display panel, comprising: a plurality of unit pixels, each of the unit pixels including first to third organic light emitting diodes having different colors, wherein each of the plurality of unit pixels further includes first to third driving transistors respectively connected to the first to third organic light emitting diodes, a first contact hole connected to one electrode of the first organic light emitting diode, a second contact hole connected to one electrode of the second organic light emitting diode, and a third contact hole connected to one electrode of the third organic light emitting diode, and are arranged in a matrix, wherein a plurality of the first organic light emitting diodes are arranged in a stripe type in unit pixels which are adjacent to each other in a first direction, a plurality of the third organic light emitting diodes are arranged adjacent to each other at a boundary of respectively adjacent two unit pixels, wherein the two adjacent unit pixels form a unit pixel pair, a plurality of second sub-pixels, wherein the second organic light emitting diode is adjacent to the third organic light emitting diode in the unit pixel, and is arranged farther apart from the boundary of the two adjacent unit pixels of the unit pixel pair than the third organic light emitting diodes of the unit pixel pair, the second and third contact holes are disposed between the second and third organic light emitting diodes of a respective unit pixel, and the first to third contact holes are arranged in parallel in a second direction of a respective unit pixel, wherein the second direction is perpendicular to the first direction.
