description	A display device according to embodiments of the present disclosure may include a display panel, a data driver configured to drive by dividing a diving period into an active period and a blank period, and apply a parking voltage during the blank period, and a controller configured to vary a driving frequency in frame units according to an input image, and, according to the driving frequency, to operate a frame as a refresh frame for writing the data voltage, or operate by dividing the frame into the refresh frame and a hold frame, wherein a voltage level of the parking voltage varies according to the driving frequency. Accordingly, it is possible to prevent a stripe defects and improve the uniformity of the display panel by reducing the mura of a parking voltage, thereby improving image quality.
