Provided is a display device capable of detecting battery removal and a method of removing a latent image from a panel. The display device includes a panel, and a driver unit displaying an image on the panel, wherein the driver unit comprises: a controller, generating a control signal and color data in response to a first power supply voltage; a voltage generator, generating control voltages in response to the control signal and a second power supply voltage; a voltage level controller, receiving the control voltages, outputting the control voltages in a first operation mode, and outputting the control voltages as first-level voltages in a second operation mode; and a source driver and a gate driver, controlling source lines and gate lines of the panel, respectively, in response to the color data, the control signal, and the control voltages. The first operation mode indicates that the display device is operating normally and the second operation mode indicates that the battery has been removed from the display panel.
