PURPOSE: A multi-display device is provided to remove the inconvenience in multi-tasking according to the small volume and light weight of a flat display panel and multi-display function and to minimize the space occupied by a system. CONSTITUTION: A multi-display device comprises a digital video interface(100), a first flat display panel(200), and a second flat display panel(300). The digital video interface is provided with at least one of analog video signals and digital video signals from the exterior. The video signals are output to the first flat display panel. The first flat display panel includes an analog/digital separating unit(210), an analog to digital converter(220), a display data controller(230), and a first crystal display module(240). The second flat display unit is installed on the rear face of the first display unit. The first display unit digitizes the analog video signals provided from the interface and displays the digital video signals. The second display unit displays the digital video signals provided from the interface. Therefore, a display screen of a specific size is realized without degrading resolution or reducing size. Power consumption is reduced by selectively using among plural screens.
