Abstract
An emission driving circuit comprises a pull-up circuit configured to output a first power voltage as an emission signal in response to a voltage of a pull-up control node, a first pull-down control circuit configured to control a voltage of a pull-down control node in response to the voltage of the pull-up control node, and a pull-down circuit configured to output a second power voltage as the emission signal in response to the voltage of the pull-down control node, wherein the first pull-down control circuit comprises a first transistor and a second transistor which are electrically connected in series.
