A method for fabricating an organic light emitting diode. The method uses a mask to create an anode position by etching on a substrate and forming a plural groove in the substrate. Next, the anode is formed on the bottom of the groove. A dot-matrix type mask is used to form the organic emitting layer over the anode and under a predetermined cathode position. A hole injection layer, hole transport layer and an electron transport layer are formed inside the groove. More particularly, the total thickness of the anode, the organic emitting layer, the hole injection layer, the hole transport layer and the electron transport layer is equal to the depth of the groove to provide a smooth surface of the substrate. Finally, another mask is utilized on the substrate to form a strip shaped cathode, thus completing the fabrication of the organic light emitting diode.
