It means a kind of organic electroluminescent device and fabrication method, a display

The present invention relates to the field of display technology, there is disclosed a method for preparing organic electroluminescent light emitting device and a display device, an organic electroluminescent device includes a base substrate, a package structure, an organic electroluminescent located between the substrate and the encapsulation substrate structure a light emitting structure, an FPC board and a flexible circuit; base substrate provided with traces surrounding structure; peripheral wiring structure includes a welded portion; base substrate is provided with an opening positioned away from the base substrate side of the organic electroluminescent structure to expose the surface of the welding portion recessed portion, an FPC terminal welding portion is located within the recess, and is welded to the welding portion. The above-described organic electroluminescent device, the flexible circuit board from the outside without bending the wiring pattern side of the substrate facing away from the substrate to the base substrate has a side facing away from the organic electroluminescent structure, there is no pre-frame at the organic electroluminescent device leaving space bending the flexible circuit board, it is possible to reduce the bezel width have organic electroluminescent device.
