Boosting voltage generator and display equipment having high boosting efficiency according to load amount

A boosting voltage generator and display equipment are provided to improve the display quality by generating the stable boosting voltage. A boosting voltage generator comprises an input voltage generation unit(31) and a boosting unit(45). The input voltage generation unit generates the first and second input voltages(VCI1,VCI) based on the reference voltage(Vr). The input voltage generation unit compares the reference voltage with the boosting voltage(Vfd5) which is feed-back based on the load amount of the output terminal(AVDD3), and outputs the comparison result. The boosting unit boosts the first and second input voltages, and outputs the boosting voltage output terminal. The display device comprises the display pattern and the display pattern driving unit. The display pattern driving unit has the source driver and the power supply unit. The power supply unit has the boosting voltage generator.
