A selective metal transfer (SMT) process is applied to organic light‐emitting diode (OLED) metal electrodes. Multicolored OLED device fabrication is demonstrated using a vacuum‐free, selective metal transfer process where an Al thin film (<100 nm) is transferred onto only the top of a light emitting layer containing polyvinyl carbazole. With this one‐step process, it is possible to make separate, differently colored electrodes and to drive each independently. Scale‐up of this process is relatively easy and SMT has a high potential in the industrial fabrication of metal electrodes for various organic electronics.
