Claim:
1. An organic electroluminescent display device comprising: a substrate; a thin film transistor disposed on the substrate and comprising a gate electrode and an active layer insulated with each other, and a source electrode and a drain electrode electrically connected with the active layer; an organic electroluminescent structure disposed on the substrate and comprising an anode, a luminescent layer and a cathode stacked sequentially, the anode and the drain electrode being electrically connected with each other; a metal reflective layer which is disposed in a region corresponding to the organic electroluminescent structure, the metal reflective layer and the gate electrode both being disposed on the substrate and made of the same material; and a gate insulating layer, the metal reflective layer and the gate electrode both being disposed between the gate insulating layer and the substrate, wherein the anode and the active layer are disposed in the same layer, the active layer is made of a transparent oxide semiconductor material, and the anode is made of the transparent oxide semiconductor material undergone a plasma treatment.
