Patent ID: 7449252

Claim:
An organic electroluminescent device, comprising: an anode; a cathode containing at least calcium or magnesium; a light-emitting functional portion sandwiched between the anode and the cathode; a titanium oxide particle thin layer; a lyophilic control layer; and an organic bank layer disposed on a part of the lyophilic control layer, the anode being in contact with a titanium oxide particle thin layer, the titanium oxide particle thin layer being formed in the organic electroluminescent device by a process free from heating and energy line radiation of the organic electroluminescent device, and the lyophilic control layer being discontinuous such that in a first location, the lyophilic control layer is disposed between the anode and the titanium oxide particle thin layer, and in a second location, the lyophilic control layer is not disposed between the anode and the titanium oxide particle thin layer, the anode being in contact with the titanium oxide particle thin layer at the second location.
