An organic flat light-emitting device. The device includes a transparent substrate, a transparent anode, at least one organic electro-luminescent layer, and a metal cathode. In this case, a first surface of the transparent substrate has several microstructures, and each of the microstructures has a maximum height of 100 mum. The transparent anode is formed on a second surface of the transparent substrate that is opposite to the first surface. The organic electro-luminescent layer is formed on the transparent anode. The metal cathode is formed on the organic electro-luminescent layer. Furthermore, the invention also discloses another organic flat light-emitting device, which includes a transparent substrate, a transparent thin film, a transparent anode, at least one organic electro-luminescent layer, and a metal cathode. The transparent thin film is formed on a first surface of the transparent substrate. The transparent thin film has a plurality of microstructures, each of which has a maximum height of 100 mum. The transparent anode is formed on a second surface of the transparent substrate opposite to the first surface. The organic electro-luminescent layer is formed on the transparent anode. The metal cathode is formed on the organic electro-luminescent layer.
