Abstract
An organic light-emitting device includes: an anode, an emitting layer, and a cathode that are stacked; a first functional material layer located between the emitting layer and the anode; and a second functional material layer located between the emitting layer and the cathode. Under a same test condition, a hole mobility of a material of the first functional material layer is at least ten times an electron mobility of a material of the second functional material layer.
