Abstract: An organic light-emitting display panel may prevent current leakage to an adjacent sub-pixel through a common layer having high hole mobility via the arrangement of an auxiliary pattern. The organic light-emitting display panel includes a bank provided in a non-emission portion so as to overlap an edge of a first electrode, a first common layer located on the first electrode in an emission portion and the bank in the non-emission portion, and an auxiliary pattern in contact with the first common layer on the bank.
