Abstract
Disclosed are a power supply apparatus and a display device including the same, which prevent damage caused by an overcurrent. The power supply apparatus includes a voltage converter configured to convert an input power into a DC voltage by using an inductor, a voltage stabilizer configured to stabilize the DC voltage which is supplied from the voltage converter through an intermediate node, and output the stabilized DC voltage to an output terminal, and an overcurrent cutoff unit connected between the voltage converter and the intermediate node, and configured to cut off an overcurrent which flows from the voltage converter to the intermediate node, based on a voltage of the intermediate node.
