ABSTRACT:
Exemplary embodiments relate to a substrate testing device having a comparator adapted to compare a power supply voltage supplied by a power supply voltage line with a dropped power supply voltage detected by a power supply voltage detection line and to output a voltage difference, and a level shifter circuit adapted to compensate a data voltage with a voltage up to an amount equal to the voltage difference output from the comparator and to supply the data voltage to a display panel.
