Abstract:
An organic electroluminescent device, a method for manufacturing the same, and a display device. The organic electroluminescent device includes: a base substrate comprising a plurality of pixel regions thereon; a pixel electrode layer; a planarization layer, formed with a protrusion on a surface of the planarization layer facing away from the base substrate and at a position corresponding to at least one side edge of a periphery of each pixel region; an anode layer, the anode layer being electrically connected to the pixel electrode layer through a via hole, and the anode layer covering the pixel region and covering a side surface of the protrusion facing the pixel region; a light emitting layer, a height of a surface of the light emitting layer being less than a height of the anode layer covering the side surface of the protrusion; a pixel definition layer; and a cathode layer.

Claim (Index 20):
The method according to  claim 19 , wherein the semi-transparent mask patterning process comprises:\n coating a photoresist layer on the planarization layer; exposing and developing the photoresist layer by an exposing process, wherein a portion of the planarization layer corresponding to the via hole is fully exposed to a light, and a portion of the planarization layer corresponding to the protrusion is unexposed to the light, and the remaining portion of the planarization layer is half-exposed to the light; performing a first etching to the portion of the planarization layer corresponding to the via hole, and removing the portion of the planarization layer corresponding to the via hole to form the via hole; performing an ashing treatment to the photoresist in such a way that a certain thickness of the photoresist in the planarization layer corresponding to the protrusion is maintained and all other photoresist in the planarization layer other than the photoresist corresponding to the protrusion is removed; performing a second etching to the planarization layer to partially remove a portion of the planarization layer other than the portion corresponding to the via hole and the protrusion, to form the protrusion; and removing the photoresist corresponding to the protrusion.
