Original Abstract Submitted

A light-emitting device includes a first electrode and a second electrode arranged opposite to each other, and a light-emitting functional layer located between the first electrode and the second electrode. The light-emitting functional layer includes a first light-emitting layer, and the first light-emitting layer includes a first light-emitting material. The first light-emitting material is configured to emit light in response to a control of an electrical signal on the first electrode and an electrical signal on the second electrode. The light-emitting functional layer further includes a second light-emitting material. A difference between a Stokes shift of the first light-emitting material and a Stokes shift of the second light-emitting material is in a range of 10 nm to 50 nm, inclusive.
