Title:
QUANTUM DOT LIGHT-EMITTING DEVICE AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/060375
Kind Code:
A1
Abstract:
Provided in the present disclosure are a display panel and a display apparatus. The display panel comprises a first electrode layer, an electron transport layer, a light-emitting layer, a hole transport layer, a hole injection layer and a second electrode layer, which are sequentially arranged in a stacked manner, wherein the material of the hole injection layer comprises a first metal oxide and a second metal oxide, metal elements contained in the first metal oxide and the second metal oxide being the same, but the number of electrons in the outermost layers of the metal elements being different. In addition, the hole injection layer further comprises a metal M and a third metal oxide MOy, which is obtained by means of an oxidation-reduction reaction between the metal M and the first metal oxide. The hole injection layer may be of a single-layer or multi-layer structure.
