摘要： An organic EL device has a hole injecting electrode (2), an electron injecting electrode (3), an organic layer (5) between the electrodes, and an inorganic insulating hole injecting layer (4) between the hole injecting electrode (2) and the organic layer (5). The inorganic insulating hole injecting layer (4) consists essentially of silicon oxide or germanium oxide or a mixture of silicon oxide and germanium oxide in an average composition represented by (Si1-xGex)Oy wherein x and y are 0≦x≦1 and 1.7≦y≦1.99, as analyzed by Rutherford back-scattering. The device has the advantages of both organic and inorganic materials as well as a long lifetime, improved efficiency, low operating voltage, and low cost.
