A manufacturing method of organic flat emitting devices, including a transparent
electrode substrate forming step, an insulation layer forming step, a curing step,
an organic electroluminescent layer forming step, and a metallic cathode forming
step. In the transparent electrode substrate forming step, a plurality of separate
transparent anodes are formed on a transparent substrate. In the insulation layer
forming step, an insulation layer is formed around the transparent anode by ink-jet
printing. In the curing step, the insulation layer is cured to form a transparent
electrode plate. In the organic electroluminescent layer forming step, an organic
electroluminescent layer is formed on the transparent electrode plate having the
transparent anode and the insulation layer formed thereon. In the metallic cathode
forming step, metallic cathodes 13 are formed on the organic electroluminescent
layer. Furthermore, the invention also discloses a manufacturing method of transparent
electrode plates.
