Abstract

The present disclosure provides a display panel and a display apparatus. The display panel includes 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 stacked, a material of the hole injection layer includes a first metal oxide and a second metal oxide, which contain the same metal element, the number of outermost electrons of the metal element in the first metal oxide is different from the number of outermost electrons of the metal in the second metal oxide. In addition, the hole injection layer further includes a metal M and a third metal oxide MOy, the third metal oxide MOy is formed by an oxidation-reduction reaction between the metal M and the first metal oxide. The hole injection layer may be of a single layer or a multi-layer structure.
