When the front-end|tip part of the knife edge 31c of the 1st optical component sheet|seat F1 is folded back at an acute angle, the separator sheet F3a is peeled from the bonding sheet|seat F5. At this time, adhesive layer F2a (bonding surface with liquid crystal panel P) of bonding sheet F5 faces downward. Just below the front end of the knife edge 31c is the spacer peeling position 31e, and the holding surface 32a of the bonding head 32 contacts the front end of the knife edge 31c from above, whereby the surface protection film of the sheet of the sheet F5 is bonded. F4a (the surface on the opposite side to the bonding surface) is stuck on the holding surface 32a of the bonding head 32 .

As shown in FIGS. 6 and 7 , the suction table 41 is arranged at a position adjacent to the knife edge 31c along the sheet conveyance direction. The suction table 41 suctions and holds the liquid crystal panel P at the time of bonding. The suction stage 41 has the suction surface 41a which suctions and holds liquid crystal panel P. As shown in FIG.

The recovery table 42 is arranged at a position not to overlap the adsorption table 41 when viewed from the normal direction of the adsorption surface 41 a.

For example, after the cutting device 31b cuts the bonding sheet F5 and the bonding sheet F5 is released by a sheet amount, when the cutting end of the cutting device 31b moves from the specified reference position In the case of deviation, the deviation is corrected by the movement of the cutting device 31b. Moreover, the cutting of the bonding sheet|seat F5 which differs in length can also be handled by the movement of the cutting apparatus 31b. In addition, cutting of defective sheets having different lengths can be handled by moving the cutting device 31b.

When the bonding sheet F5 is moved from the spacer peeling position 31e to the first bonding position 11c, the pair of second detection cameras 35 are used to paste and hold the bonding sheet F5 on the holding surface 32a, for example, opposite to the front end. The two corner parts of the base end are photographed. The detection data of each second detection camera 35 is sent to the control device 25 . The control device 25, for example, confirms the horizontal direction of the bonding sheet F5 relative to the bonding head 32 (the moving direction of the bonding head 32 and its orthogonal direction and the direction centered on the vertical axis) based on the imaging data of each second detection camera 35. direction of rotation). When the relative position of the bonding head 32 and the bonding sheet|seat F5 deviates, the bonding head 32 aligns so that the position of the bonding sheet|seat F5 (1st optical member F11) may become predetermined reference position.

In addition, the description of the bonding process performed by the 2nd and 3rd bonding apparatuses 15 and 18 which have the same structure as the 1st bonding apparatus 13 is abbreviate|omitted.

In the present embodiment, the first bonding apparatus 13 cuts out a sheet (first sheet F1m) of the bonding sheet F5 larger than the display area P4 of the liquid crystal panel P from the first optical member sheet F1, and the bonding sheet F5 While holding the sheet (1st sheet F1m) of the bonding head 32 on the holding surface 32a, the sheet|seat (1st sheet F1m) of the bonding sheet|seat F5 is pressed and bonded to liquid crystal panel P.

Based on the detection information of each detection camera 34-38, the drive control of the suction stage 41 is performed by the control apparatus 25. As shown in FIG. Thereby, alignment of the liquid crystal panel P in each bonding position with respect to the bonding head 32 is performed.

The precision of the direction of the optical axis can improve the clarity and contrast of the optical display device.

Here, the polarizer film constituting the optical component sheet FX is formed, for example, by uniaxially stretching a PVA film dyed with a dichroic dye. Uneven dyeing causes deviation in the optical axis direction within the plane of the optical component sheet FX.

Therefore, in this embodiment, based on the inspection data of the in-plane distribution of the optical axis of each part of the optical component sheet FX stored in the storage device 24 (see FIG. The bonding position of the component sheet FX (relative bonding position). And each bonding apparatus 13,15,18 performs alignment of liquid crystal panel P with respect to the sheet|seat FXm cut out from the optical member sheet|seat FX according to this bonding position, and bonds liquid crystal panel P to sheet|seat FXm.

The determination method of the bonding position (relative bonding position) of sheet piece FXm with respect to liquid crystal panel P is as follows, for example.

First, as shown in FIG. 18A , a plurality of inspection points CP are set in the width direction of the optical component sheet FX, and the direction of the optical axis of the optical component sheet FX is inspected at each inspection point CP. The timing for inspecting the optical axis may be set at the time of manufacture of the original roll R1, or may be set during the period from when the optical member sheet FX is unwound from the original roll R1 until the half-cut is performed. The data of the optical axis direction of the optical component sheet FX is stored in a storage device (not shown) in association with the position of the optical component sheet FX (the position in the longitudinal direction and the position in the width direction of the optical component sheet FX).

The control device 25 acquires the data of the optical axis of each inspection point CP (inspection data of the in-plane distribution of the optical axis) from the storage device (not shown), and inspects the optical component sheet FX of the portion where the sheet FXm is to be cut out (by the cutting line). The direction of the average optical axis of the area divided by CL).

For example, as shown in FIG. 18B , the angle (offset angle) formed by the direction of the optical axis and the edge line EL of the optical component sheet FX is inspected at each inspection point CP, and the largest angle ( The maximum deviation angle) is set to θmax, and when the minimum angle (minimum deviation angle) is set to θmin, the average value of the maximum deviation angle θmax and the minimum deviation angle θmin is θmid (=(θmax+θmin)/2) Detection is performed as an average offset angle. And the direction which makes an average deviation angle θmid with respect to the edge line EL of the optical component sheet FX is detected as the direction of the average optical axis of the optical component sheet FX. In addition, the said offset angle can be calculated by making the direction which rotated to the left with respect to the edge line EL of the optical component sheet FX positive, and the direction which rotated to the right by negative, for example.

Then, the direction of the average optical axis of the optical component sheet FX detected by the above-mentioned method forms a desired angle with respect to the long side or short side of the display area P4 of the liquid crystal panel P, and the sheet FXm is determined relative to the liquid crystal panel P. Fitting position (relative fitting position). For example, when the direction of the optical axis of the optical component F1X is set to a direction of 90° with respect to the long side or short side of the display area P4 according to the design specifications, the average optical axis of the optical component sheet FX The sheet FXm is bonded to the liquid crystal panel P so that the direction is 90° with respect to the long side or the short side of the display region P4.

The aforementioned cutting devices 51 and 52 detect the outer peripheral edge of the display area P4 of the liquid crystal panel P by detection means such as a camera, and cut the sheet FXm bonded to the liquid crystal panel P into a ring shape along the outer peripheral edge of the display area P4. The outer peripheral edge of the display area P4 is detected by imaging the end of the liquid crystal panel P, the alignment mark provided on the liquid crystal panel P, or the outermost edge of the black dot matrix provided in the display area P4. A frame portion G (see FIG. 3 ) of a predetermined width is provided outside the display area P4 to place a sealant or the like for bonding the first and second substrates of the liquid crystal panel P, and the cutting device 51 passes through the width of the frame portion G , 52 cuts the sheet FXm.

In addition, the detection method of the direction of the average optical axis in the plane of the optical component sheet|seat FX is not limited to the said method. For example, one or more inspection points CP may be selected from among a plurality of inspection points CP (see FIG. 18A ) set in the width direction of the optical component sheet FX, and each selected inspection point CP The angle (shift angle) which the direction of an optical axis makes with the edge line EL of the optical component sheet|seat FX is detected, respectively. And, the average value of the deviation angles in the optical axis direction of the selected one or more inspection points CP is detected as an average deviation angle, and the average deviation angle with respect to the edge line EL of the optical component sheet FX is The direction of the corner is detected as the direction of the average optical axis of the optical component sheet FX.

The belt-shaped optical component sheet FX that is wider than the length of any one of the short sides is unwound from the blank roll R1, and at the same time, the optical component sheet FX is made to be longer than the length of any other side of the long side and the short side of the display area P4. After the length is cut to be the sheet FXm, the sheet FXm is bonded to the liquid crystal panel P; The excess part outside the part forms the optical component F1X of the size corresponding to the display area P4, and the laminating devices 13, 15, 18 include: the unwinding part 31a that unwinds the optical component sheet FX and the spacer sheet F3a from the blank roll R1 A judging section that judges whether the optical component sheet FX discharged from the unwinding section 31a contains defects; based on the judgment result of the judging section, the optical component sheet FX is cut in a manner that leaves the spacer sheet F3a to form an acceptable sheet without defects Or a cutting device 31b for unqualified sheets containing defects; a knife edge 31c for peeling off a qualified sheet or an unqualified sheet from the spacer F3a; an adsorption table 41 with an adsorption surface 41a for holding the liquid crystal panel P by adsorption; When viewed in the normal direction of the surface 41a, a recovery platform 42 that does not overlap with the adsorption platform 41 and recovers unqualified sheets; holds the qualified sheets peeled off from the separator F3a and sticks them to the liquid crystal panel P, and Hold the unqualified sheet peeled off from the separator F3a and stick it to the bonding head 32 of the recovery station 42; make the bonding head 32 between the knife edge 31c and the liquid crystal panel P, or the knife edge 31c and the recycling Mobile device 70 for moving between stations 42.

According to this configuration, defective sheets can be discarded and pasted to the collection table 42 .

Therefore, defective flakes can be removed without using a removal film or the like independent of the separator. In addition, compared with the configuration in which the reject film and the defective sheet are collected independently of the spacer, the reject film can be omitted, and the cost required for the reject film can be saved. In addition, since defective sheets can be recovered by the recovery table 42, it is not necessary to separately install a device for recovering the film for removal, and the device structure can be simplified.
