摘要： PROBLEM TO BE SOLVED: To provide an EL(electroluminescence) element with excellent flexibility and an illuminating unit with excellent operating feeling, when used as a back light for a display part of various electronics. SOLUTION: An EL element 23 is structured by forming a light transmitting electrode layer 22 by printing on an entire surface or a designated area of one side of light transmitting insulating film 21 with a thickness of 5-50 μm by using flexible light transmitting resin with conductive powder dispersed, and also an illuminating unit is structured by using it. Thereby, since a thickness of the insulating film 21 becomes thin and the light transmitting electrode layer 22 has flexibility, an EL element with low rigidity and excellent flexibility can be obtained.

摘要： PROBLEM TO BE SOLVED: To prevent the characteristic deterioration of a P-channel FET in the power consumption reduction mode of a semiconductor integrated circuit. SOLUTION: The power source of a digital circuit part is interrupted for reducing power consumption and the output voltage of the power source is made to be zero. A CMOS inverter 10 manufactured by a dual gate process in the digital circuit part has a P-channel FET 11 having a gate electrode formed of P-type polysilicon. The source electrode of the P-channel FET 11 is connected to the power source and the back gate electrode of the P-channel FET 11 is connected to the source electrode. When the power source is interrupted in a power consumption reduction mode, the P-channel FET 11 does not function as a transistor. A pull-down switch 24 for fixing the voltage of the gate electrode of the P-channel FET 11 to zero in the mode is provided so that the characteristic deterioration of the P-channel FET 11 is prevented in the same mode.
