Abstract
A method for making an organic light emitting diode includes providing a preform structure including an anode electrode, a hole transport layer, and an organic light emitting layer stacked on each other in that order. A carbon nanotube composite structure including a polymer and a plurality of first carbon nanotubes dispersed in the polymer is also provided. The plurality of first carbon nanotubes is substantially parallel to each other, and a part of surface of the plurality of first carbon nanotubes is exposed from the polymer. The preform structure, the carbon nanotube composite structure and a cathode electrode are stacked on each other in that order.
