PROBLEM TO BE SOLVED: To obtain an excellent display quality by minimizing an interstice (a joint) width between adjacent screens in a multi-screen device installed by stacking plural screens. SOLUTION: In the case of stacking and installing plural display units up and down and right and left by making the display unit constituted of the screen 1, a screen frame 2, a main body frame 3 and a projector 4 as one unit, the main body frame 3 and the screen frame 2 are temporarily fixed by a screw 11 and a nut 12, and next adjacent main body frames 3 are mutually joined and fixed by a screw 13 and a nut 14, and adjacent screen frames 2 are mutually joined and fixed by a screw 5 and a nut 6 at last. A joint width caused between the adjacent screens 1 is minimized, and also the joint width is uniformized without having variation even in the case of having the joints at plural points.
