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.

Abstract: Disclosed is a display device integrated with a touch screen panel and a method for fabricating the same. The display includes: a TFT positioned at each pixel region; a first electrode spaced from one of a source electrode or a drain electrode of the TFT; a second electrode facing the first electrode; a TFT protective layer positioned on the TFT and has a first contact hole; a touch signal line positioned between a first touch connection pattern, which is made of the same material as the first electrode, and a second touch connection pattern made of the same material as the second electrode, and transfers a touch driving signal to the second touch connection pattern; a first connection pattern made of the same material as the second electrode; and a first electrode protective layer positioned on the first electrode and the touch signal line.
