QUANTUM-DOT LIGHT EMITTING DIODE

摘要

PURPOSE: A quantum dot light emitting device is provided to smoothly inject a hole into a quantum dot by forming an inorganic film making low energy barrier of the hole between an anode and a quantum light emitting layer. CONSTITUTION: An anode(110) and cathode(150) are formed to be faced. A quantum light emitting layer(130) is formed between the anode and the cathode. A hole-transport layer(120) is formed between the anode and the quantum light emitting layer. A electron-transport layer(140) is formed between the quantum light emitting layer and the cathode. An inorganic film(125) is formed between the anode and the quantum light emitting layer. The inorganic film is formed by a solution process or heat evaporation.
