Abstract: An organic light emitting display panel includes a first pixel and a second pixel respectively disposed in first and second light emitting areas. A portion of a first hole transport layer and a portion of a first light emitting layer of the first pixel are disposed in the second light emitting area. The portions of the first hole transport layer and the first light emitting layer overlap a second hole transport layer and a second light emitting layer, which are successively stacked. The second hole transport layer and the second light emitting layer block holes and electrons from moving to the portion of the first light emitting layer.
