Zusammenfassung:	PURPOSE:To enhance the display grades of videos by minimizing the joint width of a large-sized screen. CONSTITUTION:The large-sized screen 3 is formed by joining the end faces of four sheets of Fresnel lens sheets 10a to 10d to form a combined Fresnel lens sheet 8, adhering the end faces of two sheets of lenticular sheets 9a, 9b to form a combined lenticular sheet 7 and superposing these sheets 8, 7 on each other. An adhesive surface 12a in a transverse direction and an adhesive surface 12b in a longitudinal direction are generated as the adhesive surfaces of the Fresnel lens sheets 10a to 10d. The screen is provided with a vertical partition plate 14 along adhesive surface 12a and a lateral partition plate 13 along with this adhesive surface 12b, respectively. The vertical partition plate 14 is supported at plural points on a transverse frame 21. The vertical partition plate 14 is adjusted to be made flush with the adhesive surface 12a by these supporting means. The lateral partition plate 13 is also supported at plural points on a longitudinal frame 20. The lateral partition plate 13 is adjusted to be made flush with the adhesive surface 12b by these supporting means.
