ABSTRACT:
This invention provides a method for manufacturing a combination-type optical film comprising a plurality of optical films each having at least one end face at which the optical films are opposed to one another, comprising the steps of:(1) opposing the end faces of the optical films to one another with a gap provided therebetween;(2) entirely holding the opposed portions of the optical films with a holding member placed on at least one side;(3) connecting an organic solvent- or adhesive-containing vessel to one side of the gap between the opposed portions of the optical films to charge the organic solvent or the adhesive into the gap with the aid of a negative pressure state; and(4) removing the organic solvent or the adhesive under reduced pressure to bond the opposed end faces to one another.
