Abstract
Embodiments provide a light-emitting device including a first electrode, a second electrode facing the first electrode, m emitting units between the first electrode and the second electrode, and m-1 charge generation layers between adjacent ones of the m emitting units, wherein m is an integer of 3 or more, and the emitting units include a first emitting unit, a second emitting unit, and a third emitting unit. The first emitting unit includes a first-first host and a first-second host, the second emitting unit includes a second-first host and a second-second host, the third emitting unit includes a third-first host and a third-second host, and Tvalues of hosts of at least one of a first emitting unit, a second emitting unit, and a third emitting unit are each smaller than Tvalues of hosts of the other emitting units.
