Abstract

According to the present disclosure, when an emission boosting capacitor is electrically floated, a voltage of a gate node of a driving TFT is periodically boosted in response to a boosting clock signal. Thus, even when a current leakage occurs in the TFT in a high temperature environment, an emission output voltage of an inverter is not lowered and thus a defect such as an irregular horizontal line pattern, that is, horizontal pixel lines of a display panel are irregularly darkened is prevented so that display quality is improved.
