QUANTUM DOT LIGHT EMITTING DIODE DEVICE AND DISPLAY USING THE SAME

摘要

PURPOSE: A quantum dot light emitting diode device and a display using the same are provided to prevent a hole-transport layer from being solved in a solution by forming the hole-transport layer after a liquid solution process for forming the quantum dot light emitting diode. CONSTITUTION: In a quantum dot light emitting diode device and a display using the same, a cathode(310) is formed on a substrate(300). A quantum dot light-emitting layer(330) is formed on the cathode. An anode(350) is formed on the quantum dot light-emitting layer. An electron-transport layer(320) is formed between the cathode and the quantum dot light-emitting layer. A hole-transport layer(340) is formed between the quantum dot light-emitting layer and the anode.
