Abstract: A display panel and an organic light emitting display device with enhanced light extraction efficiency is described. The display panel and the display device include an insulating film including at least one concave portion, a first electrode disposed to cover the concave portion, a bank including a first part on the first electrode and overlapping a part of the flat portion of the concave portion, a second part extending from the first part and overlapping an inclined portion of the concave portion, and a third part extending from the second part and disposed on the side portion, an organic layer overlapping the concave portion, and a second electrode on the organic layer and the bank. A width of the first part of the bank is wider than a width of the second part of the bank. Thus, it is possible to provide a display device with enhanced light extraction efficiency.
