A plasma display apparatus is provided to enhance a contrast ratio by adjusting the slope and magnitude of set-up and set-down signals according to temperature variation. A plasma display apparatus includes a reset driver(40) for generating a reset signal having a set-up signal, which is gradually increased, and a set-down, which is gradually decreased. The reset driver, which adjusts the slope and magnitude of set-up and set-down signals by varying resistance based on temperature variation, includes first and second switch(Set_up,Set_dn). The first switch generates the set-up signal. The second switch generates the set-down signal. The first and second switch which is gates respectively is connected to a thermistor, of which resistance is exponentially varied based on the temperature variation.
