Abstract:
A liquid crystal driving device includes, for each of a plurality of scanning lines, a level shift and output buffer circuit including a first PMOSFET and a first NMOSFET connected in series, a second PMOSFET and a second NMOSFET connected in series, and CMOS inverter circuit. A gate of the first PMOSFET and a gate of the second NMOSFET may be connected to respective bias voltages. Alternatively, a gate of the first NMOSFET and a gate of the second PMOSFET may be connected to respective bias voltages. Each level shift and output buffer circuit receives a binary input signal and outputs a buffered signal having both levels shifted with respect to the input signal using six transistors.
