PROBLEM TO BE SOLVED: To provide a light emitting element improved in luminous efficiency.SOLUTION: A light emitting element includes: a negative electrode; a positive electrode; a light emitting layer arranged between the negative electrode and the positive electrode; and an organic layer arranged by being joined to the light emitting layer between the negative electrode and the light emitting layer. The organic layer includes a conjugated compound having three or more structural units represented by the following formula (1), and an ionization potential of the conjugated compound is higher than that of the compound forming the light emitting layer by 0.2 eV or more. (In the formula, Arrepresents a divalent aromatic group which has m number of fluorine atoms as a substituent and may have a substituent other than fluorine atoms, and m represents an integer of 1 or more.) |
