ABSTRACT:
In a driver circuit of a display device, an electric potential difference between high-level power supply voltage VDD and low-level power supply voltage VSS2 in shift registers and buffers is set smaller than an electric potential difference between high-level voltage VDD and low-level voltage VSS of enable signals OE in order to prevent increase in voltage stress on each transistor and concurrently to make larger an electric potential difference between high-level voltage and low-level voltage of output signals.
