Patent ID: 8915281

Claim:
A manufacturing system of an optical display unit in which an optical film is adhered to a display substrate with a pressure-sensitive adhesive layer interposed therebetween, comprising: a laminated sheet material including a pressure-sensitive adhesive type optical film having the pressure sensitive adhesive layer, the pressure-sensitive adhesive type optical film being laminated to a release film by the pressure-sensitive adhesive layer, the pressure sensitive adhesive type optical film being cut into a shape corresponding to a shape of the display substrate and the release film being uncut; a feeder for feeding the laminated sheet material; a peeling apparatus for peeling the pressure-sensitive adhesive type optical film cut to the shape corresponding to the shape of the display substrate from the release film; and an optical film bonding apparatus for bonding the pressure-sensitive adhesive type optical film peeled from the release film in the pressure-sensitive adhesive layer to the display substrate, wherein the feeder includes: a feed direction changing apparatus positioned in an opposite side to the optical film with respect to the release film, and for changing a feed direction of the pressure-sensitive adhesive type optical film; and a peeling preventing apparatus which is arranged opposed to the feed direction changing apparatus separated by a distance which exceeds a total thickness of the laminated pressure-sensitive adhesive type optical film and the release film such that a space is formed between the entirety of the laminated pressure-sensitive adhesive type optical film and the peeling preventing apparatus while the laminated pressure-sensitive adhesive type optical film and the release film are interposed between the feed direction changing apparatus and the peeling preventing apparatus, the peeling preventing apparatus being opposed to the feed direction changing apparatus at a position at which the feed direction of the pressure-sensitive adhesive type optical film is changed, and preventing the pressure-sensitive adhesive type optical film from being peeled from the release film while the pressure-sensitive adhesive type optical film and the release film are interposed between the feed direction changing apparatus and the peeling preventing apparatus, wherein the peeling preventing apparatus has a bent shape or a curved shape that corresponds to a feed locus of the pressure-sensitive adhesive type optical film.
