Abstract:
An organic electroluminescence element display device having plural light-emitting portions arranged in a display layout comprising:a plurality of organic electroluminescence elements arranged therein as the light-emitting portions each including an anode; and a cathode, a light-emitting layer having a light-emitting function and formed of an organic compound having at least an electron transport capability or a hole transport capability, and a carrier transport layer formed of an organic compound having at least a hole transport capability or an electron transport capability, which are laminated between the anode and the cathode; and respective organic semiconductor diodes each arranged adjacent to and at the same time connected in series to an associated one of said plurality of organic electroluminescence elements, wherein each of said organic semiconductor diodes has a second anode and a second cathode; at least one hole transport thin film layer which is arranged between the second anode and the second cathode and formed of an organic compound having a hole transport capability, at least one electron transport thin film layer which is arranged between the hole transport layer and the second cathode and formed of an organic compound having an electron transport capability; and an organic p-n junction consisting of one pair of the hole transport layer and the electron transport layer being laminated one upon another, said organic semiconductor diode exhibiting nonlinear current-voltage characteristics when a voltage is applied between the hole transport layer and the electron transport layer in contact with each other.
