Abstract:
An organic electroluminescent display and method of manufacturing the same are disclosed. In one aspect, the organic electroluminescent display includes a substrate and a first electrode disposed on the substrate. It also includes a pixel definition layer disposed on the first electrode, wherein the pixel definition layer has an opening portion formed in an area overlapped with the first electrode. It further includes a lyophilic layer disposed on the first electrode and the pixel definition layer, an organic light emitting layer disposed on the lyophilic layer, and a second electrode disposed on the organic light emitting layer. The lyophilic layer includes a center portion and an edge portion. The center portion is disposed on the first electrode through the opening portion and includes at least one recess portion formed therein. The edge portion is extended from the center portion and disposed on the pixel definition layer.
