Abstract: A continuous manufacturing apparatus for an optical display unit which allows for laminating a sheet of optical functional film with a panel member, even when length of each of their long sides is wide, without lowering lamination accuracy and/or increasing generation of bubbles by lamination. In a RTP system using laminating rollers having sufficient length not being bent by their own weight, when using a sheet of optical functional film which each of long sides is longer than the length of the laminating rollers, each of the sheets of optical functional film is conveyed on a band of carrier film in a continuously aligned state such that each of short sides extend in a direction crossing a conveying direction, and peeled from the band of carrier film at a laminating part to be laminated with one of opposite surfaces of the panel member.

Abstract: A method for continuously manufacturing an optical display device includes air filtering into a laminating part in an apparatus, exhausting in coordination with the air filtering, and humidifying the laminating part so as to make relative humidity of the laminating part as 60 to 75% RH at room temperature 22° C. The method also includes sequentially supplying a rectangularly formed optical functional film having a pressure-sensitive adhesive layer with a separator laminated on one of opposite surfaces of the optical functional film to a predetermined laminating position of the laminating part and conveying a rectangular panel component to the predetermined laminating position so as to correspond to the sequentially supplied optical functional film. The method further includes peeling the separator from the optical functional film leaving the pressure-sensitive adhesive layer behind and laminating the optical functional film to one of opposite surfaces of the panel component by the pressure-sensitive adhesive layer.
