Abstract
The present disclosure provides a display device according to embodiments of the present disclosure may include including a driving transistor for driving the light emitting device, a scan transistor electrically connected to a gate node of the driving transistor, and a first control transistor electrically connected between the scan transistor and a data line, the first control transistor being turned off during a floating period of a touch driving period by a driving control signal applied to a gate node thereof and electrically disconnecting between the scan transistor and the data line, thereby improving a touch sensitivity eliminating an influence of the data line on a touch signal supply line.
