Claim 5:
6. The light-emitting device of claim 1, wherein
the light-emitting device further comprises a mixture layer between the electron control layer and the emission layer,
the electron control layer consists of an electron control compound,
the emission layer consists of at least one selected from an organic compound and a semiconductor compound,
the mixture layer consists of the electron control compound and the at least one selected from the organic compound and the semiconductor compound,
the electron control compound and the at least one selected from the organic compound and the semiconductor compound are different from the other, and
the light-emitting device satisfies Equation 1:

0≤DM/(DM+DE)<0.4,  Equation 1

wherein, in Equation 1,
DM is a thickness (nm) of the mixture layer, and
DE is a thickness (nm) of the emission layer.
