Provided is a display device. The display device includes a display panel, a gate driving circuit, a sensor part, and a control voltage generator. The gate driving circuit includes driving transistors including a first control electrode and a second control electrode. The sensor part is configured to measure an environmental factor that changes a threshold voltage of the driving transistors. The control voltage generator is configured to apply to the second control electrode a control voltage for controlling the threshold voltage of the driving transistors on the basis of the environmental factor measured by the sensor part.
