Abstract
A display apparatus includes a display panel and a power voltage generator. The power voltage generator is configured to output a power voltage to the display panel. The power voltage generator includes a discharge switching element connected to an output terminal of the power voltage generator and a discharge controller connected to a control electrode of the discharge switching element. One of a first logic power voltage and a second logic power voltage is selectively applied to the discharge controller.
