Abstract: Discussed are an organic light emitting display panel and an organic light emitting display device including the same, which allows a uniform current to flow in a plurality of driving power lines, thereby reducing consumption power. The organic light emitting display panel can include first to mth gate lines and first to nth data lines configured to define a plurality of pixel areas by intersections therebetween, a plurality of color pixels respectively provided in the plurality of pixel areas, and a plurality of driving power lines. Each of the plurality power lines is shared by two color pixels which are adjacent to each other in a first direction corresponding to a length direction of the first to mth gate lines. Two color pixels, which are adjacent to each other in a second direction corresponding to a length direction of the plurality of driving power lines, have different colors.
