摘要：
A light-emitting device comprising a pair of baseplates respectively having surfaces facing each other, each surface having an electrode formed thereon, and a light-emitting layer sandwiched between the two baseplates. The light-emitting layer contains an ionic liquid and a light-emitting material dissolved in the ionic liquid. Since the light-emitting device is made without using any organic solvent, it is highly safe, does not deteriorate in emission characteristics, and requires a decreased number of constituent materials.
