Liquid crystal driving device, and liquid crystal display device using same

A liquid crystal display device comprising:

• a liquid crystal display panel having liquid crystal cells interposed between a plurality of scanning lines and a plurality of signal lines;
• and
• a liquid crystal driving device for controlling driving of the liquid crystal cells, wherein
• the liquid crystal driving device comprises:
• a power supply monitor for monitoring, using a first power supply voltage as a drive voltage, a second power supply voltage higher than the first power supply voltage so as to generate a monitor signal that indicates whether or not the second power supply voltage is below a predetermined threshold;
• a logic unit for generating, using the first power supply voltage as a drive voltage, a reset request signal according to the monitor signal;
• a reset signal generation unit for generating, using the second power supply voltage as a drive voltage, a reset signal according to the reset request signal;
• and
• a driver unit for discharging, using the second power supply voltage as a drive voltage, the liquid crystal cells according to the reset signal.
