Abstract:
An organic EL element (Al) includes an anode (2) and a cathode (4) which are arranged opposite to each other, and an organic layer (3) intervening between the anode (2) and the cathode (4) and including a light emitting layer (3b). The cathode (4) is made of MgAg alloy and has a thickness of not more than 200 Å. Preferably, the thickness of the cathode (4) is in the range of 40 to 100 Å.
