An OLED consists of the following parts:
*Substrate (clear plastic, glass, foil) - The substrate supports the OLED.
* Anode (transparent) - The anode removes electrons (adds electron "holes") when a current flows through the device.
* Organic layers - These layers are made of organic molecules or polymers.
**Conducting layer - This layer is made of organic plastic molecules that transport "holes" from the anode. One conducting polymer used in OLEDs is polyaniline.
**Emissive layer - This layer is made of organic plastic molecules (different ones from the conducting layer) that transport electrons from the cathode; this is where light is made. One polymer used in the emissive layer is polyfluorene.
* Cathode (may or may not be transparent depending on the type of OLED) - The cathode injects electrons when a current flows through the device.[http://electronics.howstuffworks.com/oled1.htm source]
