1. A light-emitting device comprising:
a reflection electrode;
a hole transport region;
a first luminescent layer being of an electron trapping type; and
a light extraction electrode, in this order,
wherein the hole transport region of the light-emitting device and a hole transport layer of another light-emitting device are disposed continuously;
wherein the first luminescent layer includes a first surface and a second surface closer to the light extraction electrode than the first surface, and
wherein a distance between the reflection electrode and the second surface of the first luminescent layer is equivalent to a length enabling emission from the first luminescent layer to be enhanced.
