    Abstract: A light-emitting device is provided, and the light-emitting device includes a first electrode, a second electrode and at least two light-emitting units. The first electrode and the second electrode are arranged in a first direction in sequence. The at least two light-emitting units are disposed between the first electrode and the second electrode, and are arranged in a second direction, and the second direction intersects the first direction. Photons emitted by each light-emitting unit of the at least two light-emitting units include first luminescent photons and second luminescent photons. Emission time of the first luminescent photons is less than emission time of the second luminescent photons. The number of second luminescent photons emitted by at least one light-emitting unit is less than or equal to the number of first luminescent photons emitted by the at least one light-emitting unit.
