Disclosed are a display device and a drive board, which can prevent light from being transmitted through a TFT pixel even in a state in which operation of a buffer adapted to drive the TFT pixel is stopped. The display device comprises: a liquid crystal display (LCD) panel in which transmittance of liquid crystals varies depending on an application voltage; a buffer unit which generates the application voltage corresponding to a drive control signal, and provides the application voltage to the LCD panel; a switching unit which selectively provides the LCD panel with an intermediate voltage adapted to prevent light from being transmitted through the LCD panel and to have a preset magnitude; and a drive control unit which, when a preset event occurs, blocks power to be supplied to the buffer unit, and controls the switching unit to provide the intermediate voltage to the LCD panel.
