    • Disclosed are a double-sided luminescent organic light emitting device and the manufacturing method thereof. The double-sided luminescent organic light emitting device comprises a transparent substrate (21), an anode (22), a transparent cathode (25), and at least two organic light emitting structures (23a, 23b) and at least a charge-generation layer (24) set between the anode (22) and the transparent cathode (25), and the charge-generation layer (24) is set between the two neighboring organic light emitting structures (23a, 23b), the charge-generation layer (24) and the organic light emitting structures (23a, 23b) are alternately arranged. The charge-generation layer (24) includes an n-type semiconductor layer (241) and a p-type semiconductor (242) layer combined with the n-type semiconductor layer. Said double-sided light emitting organic light emitting device requires low driving current, and has high luminescence efficiency, high brightness, and high light extraction efficiency. In addition, said device enables nearly 360 degrees omnidirectional illumination, enlarges the illumination area and the application range, and has long lifetime, simple preparation procedures and low production cost.
