Layer, electron transfer layer and cathode layer；Non-drying glue layer is adhered on the anode layer by roller applications；Anode layer, hole transmission layer, hair
Together with photosphere, electron transfer layer and cathode layer are brought into close contact by vacuum evaporation mode, plastic film layers can with non-drying glue layer
Peel off repeatedly and adhesively fit together.
Preferably, described cathode layer is made using the metal of the low work functions such as Al or Ag.
Preferably, described electron transfer layer uses PBD（Tert-butyl group biphenyl phenyl oh diazole）Deng fluorescent dye chemical combination
Thing is made.
Preferably, described luminescent layer uses Alq3（8-hydroxyquinoline aluminium）Etc. small molecule base organic dyestuff and pigment or
Person is PPV（Poly-phenylene vinylene (ppv)）Equiconjugate macromolecular material is made.
Preferably, described hole transmission layer uses NPB（4,4-N, N-bis-N-1-naphthyl-N-phenyl-
amino-bipheny1）It is made etc. heat-staple aromatic amine compound.
Preferably, described anode layer uses ITO（Tin indium oxide）Etc. transparent or semitransparent conductive material making
Into.
Preferably, the adhesive sticker in described non-drying glue layer is to be based on No. 60 solvents, toluene and hexamethylenes etc.
Auxiliary material is made.
Preferably, described non-drying glue layer manufacturing process is, adhesive sticker uses roller applications gluing, and ensures that glue-line is equal
It is even, it is ensured that bubble-free is produced.
Preferably, described plastic film layers use PET（Polyethylene terephthalate）Be made, inner side with
Described non-drying glue layer bonding, outside is printed on graph text information.
Non-drying glue layer that the present invention is newly increased and plastic film layers will not the performance of anode layer and whole luminescent device produce
Raw influence.
Plastic film layers in the present invention are easily peeled off, and then will be printed on the plastic film layers of new graph text information and pass through
Non-drying glue layer is bonded with the anode layer of luminescent device again, reaches reusable purpose.
Flexible organic electroluminescent device obtained by the present invention as thin-type lamp box light source, can be by plastic sheeting
The stripping repeatedly of layer reaches reusable purpose with bonding, the replacing of graph-text content is more facilitated easy, while saving money
Source, reduces and wastes.
