A method for fabricating an active matrix organic electro-luminescence (OEL) display panel is provided. First, a driving circuit array including a plurality of driving circuits is formed on a substrate. A patterned conductive layer is then formed over the driving circuit array, wherein the patterned conductive layer is electrically coupled with a high voltage source and disposed above the driving circuits. Thereafter, a plurality of organic functional layers corresponding to the driving circuits is formed on the patterned conductive layer. Finally, a plurality of cathodes electrically insulated from each other is formed on the organic functional layers, wherein the each cathode is electrically coupled with the one of the driving circuits, respectively.
