The method of successively positioning and fixing n plates forming a stack (21-26) relative to a mounting face (20), includes the positioning and alignment, if necessary, of n plates (21 PROPORTIONAL 26), each plate (21-26) being retained, after it has been positioned relative to the mounting face (20) or relative to plates (21-25) which have already been positioned, by means of a vacuum in a vacuum pipe in the plates (21-25) already positioned. When all plates (21-26)are positioned and retained by a vacuum system connected to vacuum apertures (201-206) in the mounting face (20), successive plates (21-26) can be fixed relative to each other so as to form the stack of n plates (21-26). The vacuum pipes form ducts in the plates (21-25), at least one duct comprising i (i=1,2,3, . . . , n-1) corresponding apertures (215; 214, 224; 213, 223, 233; 212, 222, 232, 242; 211, 221, 231, 241, 251) in i plates (21-25) and being closed by a plate i+1 (21-26). Such stacks are used in thin-type display devices.
