Claim 6:
7. A display device comprising:
a display panel;
a driver integrated circuit connected to the display panel through a plurality of signal lines and configured to drive the display panel; and
a power voltage supply circuit configured to provide power voltages to at least one of the display panel and the driver integrated circuit,
wherein the power voltage supply circuit includes:
a voltage converter configured to convert an input voltage and output a first power voltage to a branch node;
a first output node connected to the branch node to output the first power voltage;
