Organic static induction transistors (SITs) for display devices are proposed and the basic electrical characteristics of the SITs are investigated. The organic SITs using a copper phthalocyanine (CuPc) evaporated film as an active layer have a layered structure of Au (drain)/CuPc/Al (gate)/CuPc/Au (source)/glass. The electrical characteristics show that the current flow from the source to drain electrodes is controlled by relatively low gate voltages. Furthermore, excellent characteristics such as a high current density and high speed operation are realized by applying a buried Al grid electrode as the Schottky gate. Considering the driving system of organic electroluminescence (EL) devices, basic characteristics of EL device combined with organic static induction transistor (SIT) are examined. This device structure has ITO (source)/Alq3 (emissive layer)/α-NPD (hole-transfer layer : Al gate electrode inserted)/Al (drain), structure which is almost same as a typical EL device. Current-voltage and luminescent characteristics demonstrate that the hybrid organic electroluminescence transistor works as a display device.

提出了用于显示装置的有机静电感应晶体管（SIT），并研究了该SIT的基本电特性。该有机SIT使用酞菁铜（CuPc）蒸镀膜作为有源层，具有Au（漏极）/CuPc层状结构。 /Al（栅极）/CuPc/Au（源极）/玻璃的电气特性表明，从源极到漏极的电流是由相对较低的栅极电压控制的。由于采用埋入式Al栅电极作为肖特基栅极实现了高电流密度和高速运行，考虑到有机电致发光（EL）器件的驱动系统，EL器件与有机静电感应晶体管（SIT）相结合的基本特性是：该器件结构具有ITO（源极）/Alq3（发射层）/α-NPD（空穴传输层：插入Al栅电极）/Al（漏极），结构与典型的EL器件几乎相同。电压发光特性表明混合有机电致发光晶体管可用作显示装置。
