摘要：
Provided is a light-emitting film having controllable resistivity, and a high-luminance light-emitting device, which can be driven at a low voltage, using such light-emitting film. The light-emitting film includes Cu as an addition element in a zinc sulfide compound which is a base material, wherein the zinc sulfide compound includes columnar ZnS crystals, and sites formed of copper sulfide on a grain boundary where the ZnS crystals are in contact with each other.
