PURPOSE: To prevent the interference of video light even in a state where the deviation of the video light from a projecting unit becomes larger, and also to improve the handling of the display in the case where a screen is made large in size.

CONSTITUTION: As for the front part 1 of the multiple screen display, even in the state where the deviation of the video light from the projecting unit becomes larger, the video light from the projecting unit is prevented from being projected on a lenticular lens which corresponds to other projecting units by use of a fresnel lens mount frame 11 for a fresnel lens mount unit 10, and the intereference between the video light beams is prevented. And, as for the front part 1 of the multiple screen display, the fresnel lens mount units 10 can be disassembled one by one, so that the handling of the display such as shifting, conveyance and installation is improved when the screen is made large in size.
