Organic light-emitting device, display panel, and display apparatus

A display panel, comprising an organic light-emitting device, wherein the organic light-emitting device includes an anode, two or more light-emitting units, and a cathode that are stacked one over another, wherein:

• two adjacent light-emitting units of the two or more light-emitting units are connected through a charge generation layer;
• the charge generation layer includes an N-type charge generation layer, an intermediate layer, and a P-type charge generation layer that are stacked one over another;
• the N-type charge generation layer includes a first electron transport type organic material and an N-type dopant;
• the P-type charge generation layer includes a first hole transport type organic material and a P-type dopant;
• and
• the intermediate layer has a property of transporting electrons and/or holes.
