Abstract
The present invention provides a quantum dot light-emitting diode device, which includes a substrate, a first electrode disposed on the substrate, a hole layer vertically disposed on an anode, wherein the hole layer includes a sidewall, an electron transport layer disposed on the sidewall, a quantum dot layer disposed on the electron transport layer, and a second electrode disposed on the electron transport layer. A density of the zinc oxide nanowire is high in the present disclosure, causing high light current density, which greatly improves a brightness of light to achieve a purpose of increasing a light-emitting performance of the light-emitting diode device.
