Abstract:
1. An organic electroluminescent display device, comprising: a thin film transistor and wirings disposed on a substrate having an emitting region and non-emitting region; a first insulating layer disposed on the emitting region and the non-emitting region of the substrate, wherein the first insulating layer disposed on the non-emitting region has at least one groove formed therein; a pixel electrode configured to be driven by the thin film transistor and disposed on the substrate such that a surface of the pixel electrode farthest from the substrate is farther from the substrate than the first insulating layer; a second insulating layer disposed in the non-emitting region and in the emitting region, wherein the second insulating layer fills the at least one groove formed in the first insulating layer, directly contacts the first insulating layer inside the at least one groove, and is formed of an inorganic insulating material; a light-emitting layer disposed on the pixel electrode through an opening formed in the second insulating layer; and an encapsulation member disposed on the second insulating layer in the non-emitting region.
