摘要

The electrochemiluminescence cell (10) includes a light emitting layer (12) and electrodes (13) and (14) disposed on each surface thereof. The light emitting layer (12) contains an organic polymer light emitting material and an ionic compound. The ionic compound is represented by the general formula (1). In the general formula (1), ring A1 represents an aromatic ring, X represents S, C or P, R1 represents R ′ or OR ′, R ′ represents an alkyl group, and n represents 0 or 1 B represents O, OR2 or A2, R2 represents a saturated hydrocarbon group, A2 represents an aromatic ring, bond a is a single bond or a double bond, and when X is C, n is 0, when X is P, n is 1, when X is S, n is 0 or 1, and when n is 1, the bond a between B and X is a double bond , B is O, and when X is P, the bond a between B and X is a single bond, B is OR2 or A2, d is 1 or more, and Y + represents a cation.
