Title:
How to stick an optical film on an optical display cell
Document Type and Number:
Japanese Patent JP5911035
Kind Code:
B2
Abstract:
The present invention is a method that uses: a cell assembly motherboard (B) constituted of a plurality of optical display cells arranged in a vertical direction on a substrate with sides having terminal parts being positioned in the transverse direction; and an optical film laminate roll (22) obtained by winding an optical film laminate wherein a carrier film (21e) is attached, via an adhesive layer, to an optical film having a width corresponding to the transverse width of the optical display cells excluding the terminal parts. This method includes: a step for conveying the cell assembly motherboard to a laminate position; a step for unrolling the optical film laminate from the roll and conveying the same to the laminate position; a step for successively forming a notch in the optical film laminate that is unrolled and the adhesive layer in the transverse direction with spacing in the direction of length corresponding to the vertical dimensions of the optical display cells and thereby forming a plurality of optical film sheets supported on the carrier film; and a step for peeling the optical film sheet from the carrier film such that the adhesive layer remains at the side of the optical film in the laminate position and successively attaching the optical film sheet to an optical display surface of the individual optical display cells on the cell assembly motherboard excluding the terminal parts.
