PROBLEM TO BE SOLVED: To prevent the large-screen display device consisting of plural screens from deteriorating in display performance as the number of the screens increases, make deviation in rewriting between screens characteristic of multi- screen constitution inconspicuous, and prevent part of a screen from being missing owing to a fault of an image generation part. SOLUTION: A display control part 13 sends drawing data 11 of all the screens by multicasting to display processing parts 171, 172, 173, and 174. The respective display processing parts 171, 172, 173, and 174 selects only drawing data in the screen ranges of displays 181, 182, 183, and 184 which are connected and coordinate converting means 151, 152, 153, and 154 converts the coordinate values of the selected drawing data from coordinate values on the coordinate system of the whole large screen to coordinate values on coordinate systems of their screens. Lastly, image generating means 161, 162, 163, and 164 generate images from the coordinate-converted data and displays them on the displays 181, 182, 183, and 184 to make a display on the large screen.
