Title: Manufacturing method of organic flat light-emitting devices

Abstract: A manufacturing method of organic flat light-emitting devices includes the following steps. First, a transparent substrate is provided, which has several microstructures on its first surface and the microstructures have a maximum height of 100 .mu.m from the first surface. Second, a transparent anode is formed on the second surface of the transparent substrate that is opposite to the first surface. Thirdly, at least one organic electro-luminescent layer is formed on the transparent anode. Finally, a metal cathode is formed on the organic electro-luminescent layer. Another manufacturing method of organic flat light-emitting devices includes the steps of: forming a transparent thin film on a first surface of a transparent substrate, the transparent thin film having a plurality of microstructures with a maximum height of 100 .mu.m; forming a transparent anode on a second surface of the transparent substrate opposite to the first surface; forming at least one organic electro-luminescent layer; and forming a metal cathode on the organic electro-luminescent layer.
