Abstract

The present invention provides a method that is easily applicable and can be conducted in a high efficiency even for attaching an optical film to an optical display panel having a relatively small size. The method uses a unit assembly motherboard and an optical film laminate roll. The unit assembly motherboard is structured such that a plurality of rectangular-shaped optical display units having sides on which terminal parts are formed is arranged side by side in a row in at least a vertical direction and distributed on a substrate in such a way that the sides having the terminal parts are positioned in a horizontal direction with optical display units facing upward. The optical film laminate roll is formed by rolling an optical film laminate in a continuous strip form that comprise a carrier film to which an optical film is attached via an adhesive layer. The optical film comprises at least a layer of polarization elements having a width corresponding to the width of the optical display units, which are distributed on the unit assembly motherboard and arranged in a row in the vertical direction, in the width direction under the distributed condition, excluding the terminal parts. The method comprises a step of conveying the unit assembly motherboard to a lamination position; a step of feeding out the optical film laminate from the optical film laminate roll to the laminate position; a step of sequentially forming, in the horizontal direction, notches in the optical film and the adhesive layer of the optical film laminate so fed out with spacing in lengthwise direction thereof corresponding to the vertical dimension of the optical display units, which are distributed on the unit assembly motherboard in a row in the vertical direction, under a distributed condition and forming a plurality of optical film sheets that are supported on the carrier film via the adhesive layer; and a step of stripping the optical film sheets from the carrier film at the lamination position in a condition that adhesive layer remains on a side of the optical film and sequentially attaching the stripped optical film sheets on an area of an optical display surface of each optical display unit, which is distributed on the unit assembly motherboard in the vertical direction as a row, moving in a feeding direction, excluding the terminal parts.
