Abstract

PURPOSE: To manufacture an excellent curved-surface screen by forming a reflecting surface by pressing metal foil against the forming surface of a female pattern having fine unevenness formed in a prescribed shape, by forming an unset resin layer on the metal foil and then by setting the layer after forming a curved surface by blowing gas between the femal pattern and foil.
CONSTITUTION: In the manufacture of a curved-line screen provided with fine unevenness having prescribed directional characteristics in up and down, and right and left directions, female pattern 5 with forming surface 6 with the fine unevenness and pressure board 9 are hermetically fixed with seal ring 8 interposed while the mirror surface side of metal foil 1 is opposed to surface 6. Then, the air between foil 1 and surface 6 is evacuated from exhaust opening 7 to produce a vacuum and a thermosetting resin solution of epoxy resin, etc., is injected sprayed on foil 1; and resin layer 10 is formed and then heated until its flexiblity still remains and air is pressed in from exhaust opening 7 to swell resin layer 10a and foil 1 in one body until a prescribed curved surface is obtained. Next, it is thermally set by infrared rays or light-set by ultraviolet rays to manufacture the curved-surface screen.
