The second region 101 s 2 of the sheet piece 101 separated from the chuck unit 120 is collected by the collection unit 160.

  As described above, according to the peeling apparatus 100 of the present embodiment, the second region 101s2 of the sheet piece 101 is moved upward along the second direction V2 to separate from the first region 101s1 of the sheet piece 101. Thus, the second region 101s2 can be separated from the first region 101s1 with a weak force. Therefore, it is possible to suppress a part of the second region 101s2 from being broken at the time of peeling, and to continuously peel the second region 101s2 from the first region 101s1 without interrupting the peeling of the second region 101s2.

Thus, since the second region 101s2 of the sheet piece 101 is separated from the chuck portion 120, the second region 101s2 of the sheet piece 101 can be prevented from remaining attached to the chuck portion 120 by the adhesive layer 102 at the time of peeling. .

  The first area 101s1 of the sheet piece 101 has a rectangular shape in plan view, and the chuck unit 120 chucks the first corner part 101a1 and the second corner part 101a2 in the second area 101s2 of the sheet piece 101, and hits the part 130. Hits the portion between the first corner portion 101a1 and the second corner portion 101a2 in the second region 101s2 of the sheet piece 101, so that when the hit, the force is equally applied to the second region 101s2 of the sheet piece 101. be able to. Therefore, even if the second region 101s2 of the sheet piece 101 adheres to the chuck portion 120 by the adhesive layer 102 at the time of peeling, the second region 101s2 of the sheet piece 101 can be easily separated from the chuck portion 120.

  Further, the suction table 110 overlaps the portion 101a1 of the second region 101s2 of the sheet piece 101 that is chucked by the chuck unit 120 and the portion 101a2 of the second region 101s2 of the sheet piece 101 that is chucked by the chuck unit 120 in plan view. The chuck portion 120 has a portion protruding from the tapered portion 110t1 and the tapered portion 110t2 in the second region 101s2 of the sheet piece 101 (the first corner portion 101a1 and the second corner portion 101a2). ), The first corner portion 101a1 and the second corner portion 101a2 are stably chucked by setting the protruding amounts of the first corner portion 101a1 and the second corner portion 101a2 to predetermined values, respectively. Can do. Accordingly, the second region 101s2 can be continuously and stably peeled from the first region 101s1 without interruption.

  In the present embodiment, a mechanical chuck that chucks the second region 101s2 with a mechanical force has been described as the chuck portion 120. However, the present invention is not limited to this. For example, a vacuum chuck that fixes the second region 101s2 by vacuum suction may be used.

  In the present embodiment, an example in which the peeling device 100 peels and collects from the first corner portion 101a1 and the second corner portion 101a2 of the second region 101s2 has been described. However, the present invention is not limited thereto. For example, the peeling apparatus 100 may peel off and collect from a part of the longitudinal portion of the second region 101s2. That is, it is only necessary that the peeling device 100 is configured to chuck the second region 101s2 and peel it from the first region 101s1.

  Further, in the present embodiment, the example in which the planar view shape of the second region 101s2 is a shape along the three sides of the first region 101s1 that is rectangular in plan view has been described, but the present invention is not limited thereto. For example, the planar view shape of the second region 101s2 may be a rectangular frame shape or various shapes such as an L shape.

  In this film bonding process, polarizing films (corresponding to the first optical member F11 and the second optical member F12 described above) are bonded to both the backlight side and the display surface side of the liquid crystal panel. Furthermore, a third optical member serving as a brightness enhancement film (APF: Advanced Polarizing Film) is bonded to the surface on the backlight side of the liquid crystal panel so as to overlap the first optical member F11.

  First, as shown in FIG. 16, an original fabric roll on which an optical member sheet for a polarizing film is wound is prepared (step S1 shown in FIG. 16).

  Next, a half cut is performed to cut a part in the thickness direction of the optical member sheet (step S2 shown in FIG. 16).

  Thereby, the sheet piece (equivalent to the 1st sheet piece F1m and the 2nd sheet piece F2m) of a bonding sheet larger than the display area of a liquid crystal panel is cut out from an optical member sheet | seat (step S3 shown in FIG. 16).

  Next, the surface protective film is peeled from the polarizing film (step S14 shown in FIG. 16).

  Next, the bonded body is turned (turned 90 °) (step S15 shown in FIG. 16). For example, the bonded body that has been transported with the short side of the display area along the transport direction is turned so as to be transported in the direction along the long side of the display area. Thereby, the polarization axes of the polarizing films bonded to the front and back surfaces of the liquid crystal panel are perpendicular to each other.

  Next, a sheet piece (corresponding to the second sheet piece F2m) cut into a predetermined size with respect to the lower surface of the bonded body (the surface opposite to the surface on which the polarizing film of the second optical member bonded body PA2 is bonded). ) Is performed (step S16 shown in FIG. 16). Thereby, a sheet piece is integrally bonded by the lower surface of a bonding body, and it becomes a bonding body (equivalent to 3rd optical member bonding body PA3).

  Next, the sheet piece (corresponding to the third sheet piece) cut into a predetermined size is bonded to the lower surface of the bonded body (the surface on which the polarizing film of the third optical member bonded body PA3 is bonded) ( Step S17 shown in FIG.

  Next, the front and back of the bonded body are reversed (step S18 shown in FIG. 16). Thereby, let the surface where the 3rd sheet piece of the bonding body was bonded be an upper surface.

  Next, the outer periphery of the bonding surface of the liquid crystal panel and the sheet piece to which the sheet piece is bonded is detected.

  Next, the window cut which cut | disconnects the bonded sheet piece along the outer periphery of the bonding surface is performed (step S19 shown in FIG. 16). Specifically, from the first region facing the bonding surface among the sheet pieces bonded to the bonding body, the second region which is the region outside the first region is separated, and the size corresponding to the bonding surface. A polarizing film (corresponding to the second optical member F12) and a brightness enhancement film (corresponding to the third optical member) having a size corresponding to the bonding surface are formed.

  Next, the second area separated from the sheet piece is peeled off and collected from the first area of the sheet piece (step S20 shown in FIG. 16).

  Next, the bonding variation (positional deviation) of the sheet pieces with respect to the liquid crystal panel is inspected (step S21 shown in FIG. 16).

  Next, a defect inspection is performed on the bonded body (step S22 shown in FIG. 16). For example, the AOI inspection (Automatic Optical Inspection) is used to inspect the presence or absence of poor film bonding. The bonded body on which the NG determination has been made is discharged out of the system by a not-shown dispensing means.

  Thereby, the polarizing film is bonded to both the backlight side and the display surface side of the liquid crystal panel, and the brightness enhancement film is bonded to the surface of the liquid crystal panel on the backlight side. Is obtained (step S23 shown in FIG. 16).

As a result, the optical member can be accurately provided up to the display area P4, and the frame area outside the display area P4 can be narrowed to enlarge the display area and downsize the device.
And, when collecting the second region separated from the sheet piece FXm, by moving the second region of the sheet piece FXm upward along the second direction V2 and peeling it from the first region of the sheet piece FXm, The second region can be peeled from the first region with a weak force. Therefore, it is possible to prevent the second region from being partially broken at the time of peeling, and to continuously peel the second region from the first region without interrupting the peeling of the second region.

  The size of the surplus portion of the sheet piece FXm (the size of the portion that protrudes outside the liquid crystal panel P) is appropriately set according to the size of the liquid crystal panel P. For example, when the sheet piece FXm is applied to a medium-to-small size liquid crystal panel P of 5 to 10 inches, the distance between one side of the sheet piece FXm and one side of the liquid crystal panel P is 2 mm on each side of the sheet piece FXm.
