Organic EL element for multi-color emission

摘要

An organic EL element includes a luminescent layer containing an organic compound and sandwiched between an anode and a cathode. The luminescent layer is composed of a hole-transporting luminescent layer and an electron-transporting luminescent layer. Both luminescent layers emit light simultaneously. Each of the hole-transporting luminescent layer and the electron-transporting luminescent layer includes two or more kinds of fluorescent materials so that the emission spectrum from the hole-transporting luminescent layer 4a substantially confirms the emission spectrum from of the electron-transporting luminescent layer.
