To cut endlessly. By cutting the optical member sheets F1 and F2 together after being bonded to the liquid crystal panel P, the accuracy in the optical axis direction of the optical member sheets F1 and F2 is increased, and the opticalness between the optical member sheets F1 and F2 is increased. The axial displacement is eliminated, and the cutting with the first cutting device 13 is simplified.

  By the cutting | disconnection of the 2nd cutting device 16, the 2nd single-sided bonding panel P12 by which the 1st and 2nd optical members F11 and F12 were accumulated and bonded on the upper surface of liquid crystal panel P is formed (refer FIG. 7). Moreover, at this time, as shown in FIG. 2, each optical member sheet | seat F1, F2 which the opposing part (each optical member F11, F12) of the 2nd single-sided bonding panel P12 and the display area P4 is cut off, and remains in frame shape.

  Referring to FIG. 1, the third alignment device 17 reverses the second single-sided bonding panel P12 with the backlight side of the liquid crystal panel P as the upper surface so that the display surface side of the liquid crystal panel P is the upper surface. The same alignment as that of the first and second alignment devices 11 and 14 is performed.

  The pinching roll 18b has a pair of pasting rollers arranged with their axial directions parallel to each other. A predetermined gap is formed between the pair of bonding rollers, and the gap is the bonding position of the third bonding device 18. In the gap, the second single-sided bonding panel P12 and the third optical member sheet F3 are overlapped and introduced. These 2nd single-sided bonding panels P12 and the 3rd optical member sheet | seat F3 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the 3rd bonding sheet | seat F23 which bonded continuously the several 2nd single-sided bonding panel P12 on the lower surface of the elongate 3rd optical member sheet | seat F3 is formed at predetermined intervals.

  The 3rd cutting device 19 is located in a panel conveyance downstream rather than the pinching roll 18b, and cut | disconnects the 3rd optical member sheet | seat F3. The third cutting device 19 is a laser processing machine similar to the second cutting device 16, and the third optical member sheet F3 is endless along the outer peripheral edge of the display region P4 (for example, along the outer peripheral edge of the liquid crystal panel P). Disconnect.

  By the cutting | disconnection of the 3rd cutting device 19, the double-sided bonding panel P13 by which the 3rd optical member F13 was bonded on the upper surface of the 2nd single-sided bonding panel P12 is formed (refer FIG. 8). Further, at this time, the double-sided bonding panel P13 and the surplus portion (not shown) of the third optical member sheet F3 remaining in a frame shape are separated from the facing portion (third optical member F13) of the display region P4. The A plurality of surplus portions of the third optical member sheet F3 are formed in a ladder shape in a manner similar to the surplus portion Y of the second optical member sheet F2 (see FIG. 2), and the surplus portions are wound around the third recovery portion 18d.

  After the double-sided bonding panel P13 is inspected for defects (such as poor bonding) through a defect inspection device (not shown), it is transported to the downstream process and subjected to other processes.

  In general, a long optical film (corresponding to each optical member sheet F1, F2, F3) is manufactured by uniaxially stretching a resin film dyed with a dichroic dye, and the direction of the optical axis of the optical film is a resin. Generally coincides with the stretching direction of the film. However, the optical axis of the optical film is not uniform throughout the optical film, but varies slightly in the width direction of the optical film.

  For this reason, when bonding a some optical display component to the optical film in the width direction, it is desirable to align an optical display component according to the optical axis direction of an optical film. This is effective in that the variation in the optical axis of each optical display device is suppressed and the color and contrast are enhanced.

  An optical film as a polarizing film is dyed with, for example, iodine or a dichroic dye in order to block light other than light that vibrates in one direction. In addition, a peeling film and a protective film may be further laminated | stacked on the optical film.

  An inspection apparatus for inspecting the optical axis direction of an optical film includes a light source disposed on one side of the front and back of the optical film and an analyzer disposed on the other side of the front and back of the optical film. The analyzer receives the light irradiated from the light source and transmitted through the optical film, and detects the optical axis of the optical film by detecting the intensity of this light. The analyzer can move, for example, in the width direction of the optical film, and can inspect the optical axis at an arbitrary position in the width direction of the optical film.

  In the case of this embodiment, the inspection data in the optical axis direction of each optical member sheet F1, F2, F3 obtained by the inspection apparatus is associated with the longitudinal direction position and the width direction position of each optical member sheet F1, F2, F3. And stored in the memory of the control device 20. After this inspection, the optical member sheets F1, F2, and F3 are wound up to form the original rolls R1, R2, and R3, respectively. Hereinafter, the optical member sheets F1, F2, and F3 are collectively referred to as the optical member sheet FX, the liquid crystal panel P that is bonded to the optical member sheets F1, F2, and F3, and the single-sided bonding panels P11 and P12 are collectively referred to as the optical display member PX. There are things to do.

  The polarizer film constituting the optical member sheet FX is formed by, for example, uniaxially stretching a PVA film dyed with a dichroic dye, but unevenness in the thickness of the PVA film during the stretching or dyeing of the dichroic dye Due to unevenness or the like, there is a tendency that a difference in the optical axis direction occurs between the inner side in the width direction and the outer side in the width direction of the optical member sheet FX.

  Therefore, in the present embodiment, based on the inspection data of the in-plane distribution of the optical axis in each part of the optical member sheet FX stored in advance in the control device 20, the alignment of the optical display component PX to be bonded to these is performed. The optical display component PX is bonded to the optical member sheet FX.

  Specifically, for example, the optical axis having the maximum angle and the minimum optical axis with respect to a predetermined reference axis (longitudinal axis or the like) is found in the plane of the portion where the optical display component PX is bonded to the optical member sheet FX. The optical display component PX is aligned on the basis of the axis that bisects the angle formed by these optical axes as an average optical axis of the part.

  Accordingly, even when the optical display component PX is bonded to a different position in the width direction of the optical member sheet FX, the variation in the optical axis direction of the optical member sheet FX with respect to the reference position of the optical display component PX can be suppressed. The tolerance can be approximately 0 ° (allowable tolerance is ± 0.25 °).

  Note that the optical axis direction may be detected while the optical member sheet FX is unwound, and the optical display component PX may be aligned based on the detection data. The various alignment methods described above are not limited to the case where the optical axis direction of the optical member sheet FX is 0 ° and 90 °, but can be applied to any angle.

  FIG. 3 shows an example in which three optical display components PX are aligned and bonded to a relatively wide optical member sheet FX in the width direction, but the present invention is not limited to this, and two or less or four or more optical displays are displayed. It is a configuration in which the parts PX are arranged and bonded in the width direction of the optical member sheet FX, or a plurality of relatively narrow optical member sheets FX are arranged in the width direction and the optical display components PX are bonded to each of them. May be.

  Referring to FIG. 4, the liquid crystal panel P includes a rectangular first substrate P1 made of, for example, a TFT substrate, a second rectangular substrate P2 disposed opposite to the first substrate P1, and a first substrate P1. And a liquid crystal layer P3 sealed between the second substrate P2. For convenience of illustration, hatching of each layer in the cross-sectional view may be omitted.

  Referring to FIGS. 6 and 7, the first substrate P1 has three sides of the outer periphery along the corresponding three sides of the second substrate P2, and the remaining one side of the outer periphery is a corresponding side of the second substrate P2. Overhang outside. Thereby, the electrical component attachment part P5 which protrudes outside the 2nd board | substrate P2 is provided in the said one side of the 1st board | substrate P1.

  5 and 7, the second cutting device 16 detects the outer peripheral edge of the display area P4 with a detecting means such as a camera 16a, and the first and second optical members along the outer peripheral edge of the display area P4. The sheets F1 and F2 are cut. In addition, the third cutting device 19 similarly cuts the third optical member sheet F3 along the outer peripheral edge and the like of the display area P4 while detecting the outer peripheral edge of the display area P4 by a detection unit such as a camera 19a. Outside the display area P4, a frame portion G having a predetermined width for arranging a sealant or the like for joining the first and second substrates P1 and P2 is provided, and the cutting devices 16 and 19 within the width of the frame portion G are provided. Laser cutting is done.

  When the resin optical member sheet FX is laser-cut alone, the cut end may be swollen or wavy due to thermal deformation. For this reason, when the optical member sheet FX after laser cutting is bonded to the optical display component PX, poor bonding such as air mixing and distortion is likely to occur in the optical member sheet FX.

  On the other hand, in the present embodiment in which the optical member sheet FX is laser-cut after the optical member sheet FX is bonded to the liquid crystal panel P, the cut end of the optical member sheet FX is backed up on the glass surface of the liquid crystal panel P. Since the cut end of the sheet FX is not swollen, corrugated, or the like, and after being bonded to the liquid crystal panel P, the bonding failure cannot occur.

  The deflection width (tolerance) of the cutting line of the laser processing machine is smaller than that of the cutting blade. Therefore, in this embodiment, the width of the frame portion G is larger than that in the case of cutting the optical member sheet FX using the cutting blade. The liquid crystal panel P can be reduced in size and / or the display area P4 can be increased in size. This is effective for application to high-function mobile devices that require expansion of the display screen while the size of the housing is limited, such as smartphones and tablet terminals in recent years.

  In addition, when the optical member sheet FX is cut into a sheet piece aligned with the display region P4 of the liquid crystal panel P and then bonded to the liquid crystal panel P, the dimensional tolerances of the sheet piece and the liquid crystal panel P, and their relative bonding Since the positional dimensional tolerances overlap, it is difficult to reduce the width of the frame portion G of the liquid crystal panel P (it is difficult to enlarge the display area).

  On the other hand, when the optical member sheet FX is bonded to the liquid crystal panel P and then cut in accordance with the display region P4, only the runout tolerance of the cutting line needs to be considered, and the width tolerance of the frame portion G can be reduced. (± 0.1 mm or less). Also in this respect, the width of the frame part G of the liquid crystal panel P can be reduced (the display area can be enlarged).

  Further, by cutting the optical member sheet FX with a laser instead of a blade, the cutting force is not input to the liquid crystal panel P, and it becomes difficult for cracks and chips to occur at the edge of the substrate of the liquid crystal panel P, such as a heat cycle. The durability against is improved. Similarly, since there is no contact with the liquid crystal panel P, there is little damage to the electrical component mounting portion P5.

  As shown in FIG. 6, when laser cutting the optical member sheet FX (third optical member sheet F3 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display area P4, and this First, the cutting of the one long side is started from the starting point pt1. The end point pt2 of the laser cut is set at a position where the laser goes around the display area P4 and reaches the extension of the short side on the start point side of the display area P4. The start point pt1 and the end point pt2 are set so as to be able to withstand the tension when the optical member sheet FX is wound, leaving a predetermined connection allowance in the surplus portion of the optical member sheet FX.

  Here, as shown in FIG. 1, the film bonding system 1 is provided in the vicinity of the second bonding device 15, and the surplus portion Y of the second optical member sheet F2 (and the surplus of the first optical member sheet F1). The sheet conveyance carrier 21 used for peeling of the part Y ′) and the second recovery part 15d used for peeling off the surplus part Y of the second optical member sheet F2 are provided. Moreover, the film bonding system 1 is provided in the vicinity of the third bonding device 18 and is used for peeling the surplus portion Y of the third optical sheet F3, and also the third optical sheet F3. A third recovery unit 18d used for peeling off the surplus portion Y.

  Hereinafter, although the sheet | seat conveyance carrier 21 and the 2nd collection | recovery part 15d provided in proximity to the 2nd bonding apparatus 15 are demonstrated, the sheet | seat conveyance carrier 21 'provided in the vicinity of the 3rd bonding apparatus 18 and 3rd collection | recovery The part 18d is assumed to have the same configuration.

  Referring also to FIG. 9, the sheet conveyance carrier 21 is disposed below the roller conveyor 5. The sheet conveying carrier 21 sucks and holds the liquid crystal panel P (in the following description, including the second bonding sheet F22 and the second single-sided bonding panel P12), for example, by air suction from below.

  The sheet conveyance carrier 21 includes a carrier main body 22 provided so as to be movable along the panel conveyance direction, a stage 23 supported by the carrier main body 22 so as to be movable up and down, and a lower surface inside the liquid crystal panel P (display area P4). The inner suction pad 25 supported by the stage 23 to be sucked, the outer suction pad 26 supported by the stage 23 to suck the lower surface of the outside of the liquid crystal panel P (such as the electrical component mounting portion P5), and the carrier body 22 And a peeling member 24 that is fixedly supported while standing upward. The operation of the sheet conveyance carrier 21 is controlled by the control device 20.

  The carrier main body 22 is movable between a lower position of the second cutting device 16 and a lower position of the pressing roll 15e of the second recovery unit 15d. When the carrier body 22 is at a position below the second cutting device 16, the sheet transport carrier 21 also functions as a laser cutting jig, and fixes the liquid crystal panel P at a predetermined work position.

  The liquid crystal panel P includes a base plate portion (corresponding to the first substrate P1) P6 made of, for example, a TFT (Thin Film Transistor) substrate, and a counter plate portion P7 disposed to face the base plate portion P6. The counter plate portion P7 includes a relatively small substrate (corresponding to the second substrate P2) facing the base plate portion P6 and a liquid crystal layer P3 sealed therebetween. In the second cutting device 16, the liquid crystal panel P is arranged with the backlight side (base plate portion P6 side) on the upper side.

  The inner suction pad 25 of the stage 23 is sucked to the lower surface of the thick plate portion P8 including the counter plate portion P7 in the liquid crystal panel P, and the outer suction pad 26 of the stage 23 is a base outside the thick plate portion P8 in the liquid crystal panel P. The plate portion P6 is attracted to the lower surface of the main thin plate portion P9. The lower surface of the thick plate portion P8 and the lower surface of the thin plate portion P9 are connected in steps, and the liquid crystal panel P is positioned with respect to the sheet conveyance carrier 21 by the outer suction pad 26 contacting the substantially vertical step surface therebetween. The The display area P4 of the liquid crystal panel P is formed within the outer shape of the thick plate portion P8.

  Referring also to FIG. 2, the surplus portion Y left outside the display area P4 in the second optical member sheet F2 includes an upstream piece y1 extending along the component width direction on the upstream side of the panel transport, and the panel transport It has a downstream side piece y2 extending along the component width direction on the downstream side and both side pieces y3 extending along the conveying direction on both sides of the component width direction, and is formed in a rectangular frame shape in plan view.

  When the stage 23 is in its raised position, the suction pads 25 and 26 are attracted to the lower surface of the corresponding part of the liquid crystal panel P. When the stage 23 is displaced to the lowered position from this state, the liquid crystal panel P attracted by the stage 23 is also lowered integrally. When the stage 23 is in the raised position, the peeling member 24 is close to the lower surface of the second optical member sheet F2 (the lower surface of the upstream piece y1 of the surplus portion Y) on the upstream side of the liquid crystal panel P. The peeling member 24 has a front end portion 24a extending along the component width direction. When the liquid crystal panel P is displaced to the lowered position, the front end portion 24a pushes up the upstream piece y1 of the surplus portion Y from below over the entire width in the component width direction.

  The pressing roll 15e is disposed in parallel with the width direction of the second optical member sheet F2. The pressing roll 15e winds the second optical member sheet F2 (the downstream piece y2 of the surplus portion Y) around the outer peripheral surface thereof. The second optical member sheet F2 (the surplus portion Y) is wound while being peeled off from the liquid crystal panel P by driving the second recovery portion 15d including the pressing roll 15e.

Next, the operation of the sheet conveyance carrier 21 and the second collection unit 15d will be described.
First, as shown in FIG. 9, the liquid crystal panel P transported above the sheet transport carrier 21 is attracted and fixed to the stage 23 in a state where the sheet transport carrier 21 is positioned below the second cutting device 16. In this state, the second cutting device 16 performs laser cutting of the second optical member sheet F2.

  Next, as shown in FIG. 10, the second optical member sheet is obtained by rotating the pressing roll 15 e around which the surplus portion Y corresponding to the liquid crystal panel P already transported downstream rotates in the counterclockwise direction in the drawing. Pull F2 toward the second recovery section 15d. At this time, the pressing roll 15e peels the downstream piece y2 of the surplus portion Y from the downstream end t2, so that the downstream piece y2 of the surplus portion Y is peeled over the entire width in the component width direction. At this time, the sheet conveyance carrier 21 is movable in the conveyance direction, and the liquid crystal panel P and the sheet conveyance carrier 21 are pulled to the downstream side of the panel conveyance in accordance with the winding of the surplus portion Y.

  The downstream piece y2 of the surplus portion Y is peeled from the liquid crystal panel P so as to follow the rotation direction of the pressing roll 15e (generally in the tangential direction in a side view, see arrow s in the figure). At this time, the load on the liquid crystal panel P is reduced as compared with the case where the surplus portion Y is peeled off from the liquid crystal panel P along the vertical direction. It can be said that the pressing roll 15e constitutes a downstream peeling device that peels the excess portion Y (downstream piece y2) from the downstream end t2.

On the other hand, it can be said that the sheet conveying carrier 21 constitutes an upstream side peeling device that peels the surplus portion Y (upstream side piece y1) from the upstream side end t1 by the peeling member 24.
That is, as shown in FIG. 11, the sheet conveying carrier 21 moves the peeling member 24 relative to the stage 23 and the liquid crystal panel P by displacing the stage 23 attracting the liquid crystal panel P to the lowered position. Let The leading end 24a of the peeling member 24 pushes up the upstream piece y1 (upstream end t1) of the surplus portion Y so that the upstream piece y1 of the surplus portion Y is peeled over the entire width in the component width direction. .

  Next, as shown in FIG. 12, when the pressing roll 15 e further rotates, both side pieces y <b> 3 left without being peeled in the surplus portion Y are gradually peeled from the downstream side of the panel conveyance. That is, it can be said that the second recovery unit 15d also serves as an intermediate peeling device that peels the downstream piece y2 and the upstream piece y1 of the surplus portion Y and then peels the side piece y3. And the peeling part by the holding | suppressing roll 15e and the peeling part by the peeling member 24 merge, and the frame-shaped surplus part Y whole is peeled from the liquid crystal panel P reasonably.

  In the case where the upstream piece y1 is not peeled off by the peeling member 24, the both side pieces y3 of the surplus portion Y are peeled to the upstream end by the pressing roll 15e, and then the upstream side from the upstream end of the both side pieces y3 is the upstream side. The piece y1 needs to be peeled off. Then, the connection part of the upstream piece y1 and the both side pieces y3 may be broken, and the recovery of the surplus part Y may be interrupted. However, by separating the upstream piece y1 in advance by the peeling member 24 over its entire width, it becomes possible to efficiently perform the recovery of the surplus portion Y without interruption.

  As shown in FIG. 13, after the surplus portion Y is collected, for example, the entire sheet transport carrier 21 is lowered by a predetermined amount, and is moved up to a lower position of the second cutting device 16 and then raised again. Hereinafter, after the sheet conveyance carrier 21 sucks the liquid crystal panel P on the upstream side, the same processes as described above are repeated.

  As explained above, the manufacturing apparatus of the optical member bonding body in the said embodiment manufactures the 2nd single-sided bonding panel P12 formed by bonding the 2nd optical member F12 to liquid crystal panel P, On the line For a plurality of the liquid crystal panels P to be transported, a strip-shaped second optical member sheet F2 having a width wider than the display region P4 of the liquid crystal panel P in a component width direction orthogonal to the transport direction is used as a second original roll. The 2nd bonding apparatus 15 which bonds the said some liquid crystal panel P to said 2nd optical member sheet | seat F2 and makes it the 2nd bonding sheet | seat F22, unwinding from R2, and the said display of said 2nd optical member sheet | seat F2 By separating the portion facing the region P4 and the excess portion Y outside thereof, the second optical member F12 having a size corresponding to the display region P4 is cut out from the second optical member sheet F2, The second cutting device 16 that cuts out the second single-sided bonding panel P12 including the single liquid crystal panel P and the second optical member F12 that overlaps the single liquid crystal panel P from the second bonding sheet F22, and the liquid crystal panel P. A downstream peeling device (second recovery portion 15d) that peels the downstream piece y2 of the surplus portion Y, and an upstream peeling device (sheet transport carrier 21) that peels the upstream piece y1 of the surplus portion Y, An intermediate peeling device (second recovery portion 15d) that peels the side piece y3 of the surplus portion Y after peeling the downstream side piece y2 and the upstream side piece y1 of the surplus portion Y is provided.

  Similarly, the manufacturing apparatus of the optical member bonding body in the said embodiment manufactures the double-sided bonding panel P13 formed by bonding the 3rd optical member F13 to liquid crystal panel P, The some conveyed on a line With respect to the liquid crystal panel P, a belt-shaped third optical member sheet F3 having a width wider than the display area P4 of the liquid crystal panel P in the component width direction perpendicular to the conveying direction is unwound from the third original roll R3. The third laminating device 18 that forms the third laminating sheet F23 by laminating the plurality of liquid crystal panels P on the third optical member sheet F3, and the display area P4 of the third optical member sheet F3. A part and the excess part Y of the outer side are cut off, and the third optical member F13 having a size corresponding to the display area P4 is cut out from the third optical member sheet F3, thereby the third bonding sheet. 23, a third cutting device 19 that cuts out a single-sided liquid crystal panel P and a double-sided bonding panel P13 including the third optical member F13 overlapping therewith, and downstream of the surplus portion Y bonded to the liquid crystal panel P A downstream peeling device (third recovery part 18d) for peeling the side piece y2, an upstream peeling device (sheet transport carrier 21 ′) for peeling the upstream piece y1 of the surplus portion Y, and the surplus portion Y An intermediate peeling device (third recovery portion 18d) that peels the side piece y3 of the surplus portion Y after peeling the downstream piece y2 and the upstream piece y1.

According to this configuration, when the liquid crystal panel P is bonded to the optical member sheets F2 and F3 wider than the display region P4, the optical axis direction changes depending on the positions of the optical member sheets F2 and F3. However, the liquid crystal panel P can be aligned and bonded in accordance with this optical axis direction. Thereby, the precision of the optical axis direction of the optical members F12 and F13 with respect to the liquid crystal panel P can be improved, and the color and contrast of the optical display device can be increased.
Moreover, after bonding liquid crystal panel P to optical member sheet | seat F2, F3 larger than display area P4, after separating the excess part Y of optical member sheet | seat F2, F3, the optical member F12 of the size corresponding to display area P4 , F13 can be formed on the surface of the liquid crystal panel P. Thereby, the optical members F12 and F13 can be provided with high precision up to the display area P4, and the frame portion G outside the display area P4 can be narrowed to enlarge the display area and downsize the device.
And when recovering the surplus part Y cut off from the optical member sheets F2 and F3, the downstream part y2 of the surplus part Y is peeled off, and the upstream part y1 of the surplus part Y is peeled off, so that these downstream parts Even when an elongated side piece y3 is formed between the piece y2 and the upstream piece y1, the downstream piece y2 and the upstream piece y1 are separated through the side piece y3. In addition, it is possible to prevent the recovery operation from being interrupted due to the disconnection between the downstream side piece y2 and the connection between the upstream side piece y1 and the side piece y3, and the excess portion Y can be recovered continuously without interruption.

Moreover, as for the manufacturing apparatus of the said optical member bonding body, the said downstream peeling apparatus is collection | recovery parts 15d and 18d containing the pressing rolls 15e and 18e arrange | positioned along the said component width direction, The said pressing rolls 15e and 18e However, in the state where the surplus portion Y is in contact with the downstream piece y2, it rotates following the transport direction to peel off the downstream piece y2.
According to this configuration, when the downstream piece y2 of the excess portion Y of the optical member sheets F2 and F3 is peeled, the direction of the force required for the peeling is not the vertical direction of the liquid crystal panel P but the tangential direction of the pressing rolls 15e and 18e. And it is possible to prevent damage to the laminated structure of the liquid crystal panel P due to the force that peels off the surplus portion Y.

Moreover, after the said collection | recovery parts 15d and 18d peel the said downstream piece y2 of the said surplus part Y, the manufacturing apparatus of the said optical member bonding body peels the said side piece y3 which continues to the said downstream piece y2. Thus, it also serves as the intermediate peeling device.
According to this configuration, simplification by sharing the downstream peeling device and the intermediate peeling device can be achieved. In addition, the structure provided with an intermediate | middle peeling apparatus separate from collection | recovery parts 15d and 18d may be sufficient.

Moreover, the manufacturing apparatus of the said optical member bonding body WHEREIN: The said upstream peeling apparatus is relatively displaced with respect to the stage 23 which adsorb | sucks the said liquid crystal panel P on a line, and the said stage 23 adsorb | sucked And a peeling member 24 that peels off the upstream piece y1 of the surplus portion Y corresponding to the liquid crystal panel P.
According to this configuration, the upstream side piece y1 of the surplus portion Y corresponding to the liquid crystal panel P attracted by the stage 23 is peeled off, thereby the upstream side of the surplus portion Y via the elongated side piece y3 in the surplus portion Y. Compared to the case where y1 is peeled off, it is possible to prevent interruption of the collection operation due to the breakage of the connection portion between the upstream piece y1 and the side piece y3.

Moreover, the manufacturing apparatus of the said optical member bonding body is the said board | plate 23 in the said liquid crystal panel P in which the said stage 23 adsorb | sucks to the thick board part P8 which forms the said display area P4 in the said liquid crystal panel P, and the said thick board in the said liquid crystal panel P. The outer suction pad 26 is attached to the thin plate portion P9 projecting outward from the portion P8.
According to this configuration, the thin plate portion P9 outside the display area P4 in the liquid crystal panel P is also suction-fixed to the stage 23, so that the thin plate portion P9 can be prevented from being damaged and the excess portion Y can be peeled stably. it can. In addition, by positioning the outer suction pad 26 close to the step between the thick plate portion P8 and the thin plate portion P9 of the liquid crystal panel P, positioning and movement restriction in the direction along the surface of the liquid crystal panel P can be performed reliably.

Moreover, the manufacturing apparatus of the said optical member bonding body displaces the said peeling member 24 relative to the said liquid crystal panel P which the said stage 23 adsorbed by the said stage 23 being displaced leaving the said peeling member 24. FIG. The upstream piece y1 of the surplus portion Y corresponding to the liquid crystal panel P attracted by the stage 23 is peeled off.
According to this structure, compared with the case where the peeling member 24 actively displaces and peels the upstream piece y1, the structure in which the peeling member 24 and the pressing rolls 15e and 18e do not interfere with each other can be achieved.

  Here, the manufacturing method of the optical member bonding body in the said embodiment is more than the display area P4 of the said liquid crystal panel P in the component width direction orthogonal to the conveyance direction with respect to the said several liquid crystal panel P conveyed on a line.
