Abstract:
Discussed is an organic light emitting display panel. The organic light emitting display panel includes a plurality of unit pixels which each include first to third sub-pixels having different colors. The plurality of unit pixels, which each include first to third driving transistors respectively connected to the first to third sub-pixels, a first contact hole that connects the first sub-pixel to the first driving transistor, a second contact hole that connects the second sub-pixel to the second driving transistor, and a third contact hole that connects the third sub-pixel to the third driving transistor, are arranged in a matrix type.
