 OLEDs are made of:  OLEDs are made of: 
-  * an emissive layer in which electron and hole recombine: electrons being excited by an electrical field unexcite themselves by emitting a photon +  * an organic emissive layer in which electron and hole recombine: electrons being excited by an electrical field unexcite themselves by emitting a photon 
-  * a hole transport and electron transport layer above and below the emissive layer, respectively: to improve the movment of holes and electrons towards the emissive layer  +  * (optional: only for multilayer OLEDs) a hole transport and electron transport layer above and below the emissive layer, respectively: to improve the movment of holes and electrons towards the emissive layer  
-  * a hole injection layer to improve the movement of hole from the anode towards the hole transport layer+  * (optional: only for multilayer OLEDs) a hole injection layer to improve the movement of hole from the anode towards the hole transport layer
   * two electrodes: an anode under the hole injection layer and a cathode on top of the electron transport layer   * two electrodes: an anode under the hole injection layer and a cathode on top of the electron transport layer
   * a subtrate - usually glass - under the anode   * a subtrate - usually glass - under the anode
