A multi-panel display device and a method of driving the same, which can simplify a driving circuit for driving multiple flat panel display devices, thereby decreasing the fabrication cost and reducing noise, are disclosed. In the multi-panel display device configured to align the multiple flat panel display devices for representing a single image, the multi-panel display device includes at least one image display unit configured to align the multiple flat panel display devices in an n×m formation (wherein m and n are integers being equal to or different from one another, and wherein m≧1, n≧1), and at least one data converter being configured to correspond to each image display unit, dividing externally inputted video data in accordance with offset information inputted by a user, and converting the size of the divided video data, thereby providing the converted divided video data to each flat panel display device.
