  • Organic semiconductor light-emitting device and display using same
    Patent number: 7973320
    Abstract: An organic semiconductor light-emitting device having the form of a field-effect transistor and a display using this device is provided. In the device, electrons and holes can be transported. The device comprises an organic semiconductor light-emitting layer capable of emitting light by recombination of holes and electrons, a hole injection electrode for injecting holes into the organic semiconductor light-emitting layer, an electron injection electrode for injecting electrons into the organic semiconductor light-emitting layer, and a gate electrode so disposed as to be opposed to the organic semiconductor light-emitting layer between the electrodes. When a control voltage is applied to the gate electrode, the carrier distribution in the organic semiconductor light-emitting layer is controlled. Thus, the light emission can be turned on/off and the emission intensity can be modulated.
