摘要：In order to perform operations securely, a high potential power supply isconnected to a gate electrode of a P-type TFT to which data signals are input. Similarly, alow potential power supply is connected to a gate electrode of an N-type TFT. Thus, a

TFT to which data signals are input can be turned OFF during a non-operating period.Switch TFT's are provided between the high potential power supply and the P-type TFTand between the low potential power supply and the N-type TFT so as to turn the TFTOFF as required. Similarly, Switch TFT's are provided between a data signal input terminaland a P-type TFT and between a data signal input terminal and an N-type TFT such that adata signal can be input thereto as required. The switching is controlled by using a latchsignal and an inverse latch signal. Therefore, a latch circuit without a level shifter can beproduced which can operate with stability.
