Abstract: A continuous web of optical film laminate comprising, an optical film comprising a first substrate and an adhesive layer on the first substrate, a releasable film comprising a second substrate and a releasably treated layer on the second substrate, the releasably treated layer being in contact with the adhesive layer, a first conductive layer between the first substrate and the adhesive layer, and a second conductive layer between the second substrate and the releasably treated layer. The first conductive layer and the second conductive layer comprise a static electrification prevention material, such that the optical film with the first conductive layer, and the releasable film with the second conductive layer, both have a sheet resistance of 1012Ω/sq or less.

Abstract: A method for continuously manufacturing an optical display device comprises feeding a continuous web of optical film laminate including a continuous web of releasable film that includes a conductive layer and an optical film sheet that includes a conductive layer formed on the releasable film, bending the releasable film at a peeling body located in close vicinity of a lamination position, collecting the releasable film and thereby peeling the optical film sheet from the optical film laminate, sending the optical film sheet to the lamination position, and laminating the optical film sheet with a panel member which is conveyed to the lamination position by a panel conveying channel which makes at least a double-storied structure with a portion of a collecting channel where the releasable film is collected, attenuating static electrification generated on the optical film sheet, and continuously laminating the optical film sheet with the panel member.

Abstract: To provide a continuous web of optical film laminate provided with static electrification prevention function which allows for promptly attenuating static charge of optical film sheet and carrier film electrified by peeling action in RTP lamination method and apparatus. The problem has been solved with a continuous web of optical film laminate for using in RTP lamination method and apparatus, in which static electrification prevention function is provided to optical film sheets and a carrier film configuring the continuous web of optical film laminate, such that sheet resistance of each of the optical film sheets and the carrier film is 1012 Ω/sq or less so as to promptly attenuate static charge of the carrier film to be collected, which is statically electrified by peeling action, and the optical film sheets to be laminated to panel components, which are also statically electrified by peeling action.

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.
