An inverter driving circuit for an LCD is switched on/off more stably to improve heating radiation characteristics and drive efficiency. In the driving circuit, a controller supplies a first driving signal. A level shifter provides a second driving signal. A first delay circuit delays a rising section of the first driving signal to provide the first driving signal. A second delay circuit delays a falling section of the second driving signal to provide the second driving signal. Also, a power switching circuit is provided. The inverter driving circuit for the LCD, when a switching device thereof is turned off, has less current flowing in the switching device, thereby generating less heat. In addition, the inverter driving circuit prevents heat generation caused by current flowing reversely in the switching device, thereby enhancing drive efficiency.
