Claim:
1. An organic light emitting display panel comprising: a substrate having a plurality of pixel areas, each pixel area in an area defined by data lines and gate lines and including an emitting pixel portion and a non-emitting pixel portion; a pixel electrode in each of the plurality of pixel areas on the substrate; a bank in the non-emitting pixel portion of each pixel area on the substrate, the bank overlapping an edge of each pixel electrode and a thin film transistor electrically connected to each pixel electrode, and exposing a portion of each pixel electrode in the emitting pixel portion; and an organic layer on each exposed pixel electrode, wherein one or a plurality of grooves or holes are surrounded by the bank in the non-emitting pixel portion of each pixel area, and a material the same as that of the organic layer is positioned in the one or the plurality of grooves or holes surrounded by the bank, wherein sizes or depths of the one or plurality of grooves or holes formed in at least one of the plurality of pixel areas are different from sizes or depths of grooves or holes formed in other pixel areas.
