Patent ID: 8187048

Claim:
A system for manufacturing an optical display device comprising a rectangular optical display unit and an optical film bonded thereto including a polarizing plate, comprising: an optical display unit feeding apparatus for feeding an optical display unit; a first roll of a first belt-shaped sheet material, the first belt-shaped sheet material comprising a first optical film including a first polarizing plate having an absorption axis parallel to a longitudinal direction of the first polarizing plate; a first optical film feeding apparatus for drawing and feeding the first belt-shaped sheet material from the first roll of the first belt-shaped sheet material; a first cutting and bonding apparatus that comprises first bonding means for bonding the first optical film to one surface of the optical display unit, wherein the optical display unit is fed from the optical display unit feeding apparatus and the first optical film is fed from the first optical film feeding apparatus, and first cutting means for cutting the first optical film fed from the first optical film feeding apparatus; a feeder for transporting and feeding the optical display unit after the bonding of the first optical film; a second roll of a second belt-shaped sheet material, the second belt-shaped sheet material comprising a second optical film including a second polarizing plate having an absorption axis parallel to a longitudinal direction of the second polarizing plate, wherein the absorption axis of the second polarizing plate is in the same direction as the absorption axis of the first polarizing plate; a second optical film feeding apparatus for drawing and feeding the second belt-shaped sheet material from the second roll of the second belt-shaped sheet material; and a second cutting and bonding apparatus that comprises second bonding means for bonding the second optical film to another surface of the optical display unit, wherein the optical display unit is fed from the feeder and the second optical film is fed from the second optical film feeding apparatus, and second cutting means for cutting the second optical film fed from the second optical film feeding apparatus, wherein one of the first and second cutting and bonding apparatuses is configured to cut an optical film with a width corresponding to a short side of the optical display unit into a length corresponding to a long side of the optical display unit, and the other of the first and second cutting and bonding apparatuses is configured to cut an optical film with a width corresponding to the long side of the optical display unit into a length corresponding to the short side of the optical display unit, the feeder comprises a turning mechanism for turning the optical display unit to a bonding direction for the second cutting and bonding apparatus after the bonding in the first cutting and bonding apparatus, and wherein a feeding direction of the first optical film feeding apparatus is parallel to a feeding direction of the second optical film feeding apparatus.
