ORGANIC LIGHT-EMITTING DEVICE AND DISPLAY PANEL

The present disclosure provides an organic light-emitting device and a display panel. The organic light-emitting device includes a plurality of layers stacked with each other between an anode and a cathode. The plurality of layers includes a first hole transport layer, a first light-emitting layer, a first electron transport layer, an n-type charge generation layer, and a p-type charge generation layer stacked in sequence. The n-type charge generation layer includes a matrix, a first dopant, and a second dopant. The matrix is a first electron transport organic material, the first dopant is a metal quinoline complex, and the second dopant is selected from the group consisting of a rare earth metal, an alkali metal, an alkaline-earth metal, and any combination thereof. Or the matrix is a first electron transport organic material, the first dopant is a metal quinoline complex, and the second dopant is an n-type organic material.
