Abstract: An organic light-emitting diode (OLED) includes a first electrode, a hole injection layer formed on the first electrode, an inverse energy level layer formed on the hole injection layer, a hole transport layer formed on the inverse energy level layer, a light-emitting layer formed on the hole transport layer, an electron transport layer formed on the light-emitting layer, an electron injection layer formed on the electron transport layer, and a second electrode formed on the electron injection layer. The work function of the inverse energy level layer is higher than the highest occupied molecular orbital (HOMO) of the hole injection layer and the hole transport layer.
