摘要： A light-emitting electrochemical cell 10 includes an emitting layer 12 and electrodes 13 and 14, one on each side of the emitting layer 12. The emitting layer 12 contains a light-emitting material and an ionic compound. The ionic compound has general formula (1), wherein M is N or P; R1, R2, R3, and R4 each independently represent a C1-C20 saturated aliphatic group; and X is preferably an anion having a phosphoric ester bond or a sulfuric ester bond. The light-emitting material is preferably an organic light-emitting polymer, a metal complex, an organic low molecular compound, or a quantum dot.
