    Abstract: Provided is a light-emitting electrochemical cell including a light-emitting layer 3, a first electrode 1, and a second electrode 2, wherein the light-emitting layer contains an ionic compound and the ionic compound contains an anion having a silicon atom. The anion has a silicon-containing group represented, for example, by SiR1R2R3 (R1 to R3 are all bonded directly to Si) and an anion group. The anion group is represented, for example, by —SO3−, —OSO3−, or —OP(OR0)O3−. R0 to R3 are each independently an alkyl group having 1 to 4 carbon atoms. Two alkyl groups selected from R1, R2, and R3 are optionally bonded to each other to form an alkylene group having 4 or 5 carbon atoms and constituting a cyclic structure together with the silicon atom.
