Abstract
One or more embodiments of the present disclosure relate to a display device and a gate driving circuit. There is further provided with a synchronization transistor controlled according to a voltage of a Q node of a m-th scan driver (e.g., a second scan driver) and controlling an electrical connection between an output terminal of the n-th light emitting driver and a clock input terminal of the m-th scan driver, so that the rising characteristic and/or the falling characteristic of the light emission signal which is a type of the gate signal can be improved, thereby improving a threshold voltage compensation performance of the driving transistor and the image quality.
