Abstract An organic EL device has a hole injecting electrode, a negative electrode, at least one organic layer having a light emitting function between the electrodes, and a high-resistance inorganic hole injecting layer between the hole injecting electrode and the organic layer. The inorganic hole injecting layer contains silicon oxide and/or germanium oxide as a main component, represented by (Si1-xGex)Oy wherein 0 <= x <= 1 and 1.7 <= y <= 2.2, and a conductive oxide having a resistivity of up to 1×10<10> OMEGA -cm.
