PURPOSE: To transmit a power source potential from a first wiring to a second wiring without applying a potential stepped up from the power source potential to a gate electrode. CONSTITUTION: CMOS transistors 23, 24 formed by connecting N-channel transistors 15, 16 to P-channel transistors 21, 22 in parallel are used for transmitting a potential. Thus, when a power source potential Vcc and -Vcc of its inverted potential are applied to the gate electrodes of the transistors 15, 16 and 21, 22, the potential Vcc is transmitted from a wide plate wiring 17 to a local plate wiring 14 without causing drop of a threshold voltage Vth . |
