A display device includes: a display panel; a gate driving unit and a data driving unit; a controller; and a reset circuit. The reset circuit is configured to generate a first reset signal corresponding to an operation of the display panel in one of a first driving mode or a second driving mode, and a second reset signal corresponding to a switch from the first driving mode to the second driving mode or a switch from the second driving mode to the first driving mode. The reset circuit provides the reset signals to the controller to control the first driving mode and the second driving mode of the display panel. The display device may thus switch between first and second driving modes during operation in either of the first or second driving modes, thereby improving a stain and a color difference of a displayed image.
