Abstract

A light emitting diode device and a manufacturing method thereof, a display panel, and a display apparatus are provided. The light emitting diode device includes a quantum dot light emitting layer and a hole transport layer on a side of the quantum dot light emitting layer. The hole transport layer includes a perovskite material and an organic hole transport material. The high carrier mobility of the perovskite material can improve the carrier transport performance of the hole transport layer.
