Description

Method for manufacturing laminated body of optical display device

The present invention relates to a method of manufacturing a laminate of an optical display device. More specifically, the present invention relates to a layer for manufacturing an optical display device by laminating optical film sheets containing polarizing films on both sides of a rectangular liquid crystal panel in such a way that the absorption axis is orthogonal to the polarization relationship. The integrated method, in which the other side of the liquid crystal panel will contain the optical film sheet of the other polarizing film corresponding to the width or length of the liquid crystal panel, and the side of the liquid crystal panel will be laminated in advance. A method of manufacturing a laminate in which the optical film sheet of the film is exposed from the side other than the long side of the liquid crystal panel.

At the manufacturing site of the optical display device, a manufacturing method of roll-to-panel (RTP) is adopted (for example, Patent Document 1). In the RTP method, generally, an optical display device is manufactured in the following manner. First, the optical film laminate having a predetermined width is sent out from the roller. The optical film laminate is composed of a carrier film, an adhesive layer formed on one side of the carrier film, and an optical film containing a polarizing film supported on the carrier film by the adhesive layer. The optical film may be a single layer or multiple layers. In the optical film laminate that is sent out, normally, by continuously scribing cut lines in the width direction, an optical film sheet including a polarizing film is formed between adjacent cut lines.

The optical film sheet including the polarizing film continuously supported on the carrier film is peeled from the carrier film together with the adhesive layer by the peeling mechanism arranged near the bonding position and sent to the bonding position. In the peeling mechanism, the carrier film side of the optical film laminate is wound around the top of the slightly wedge-shaped peeling mechanism having the top facing the bonding position. The optical film sheet is conveyed by turning the carrier film rolled in by the peeling mechanism in a direction substantially opposite to the conveying direction of the optical film toward the bonding position, and is peeled from the carrier film together with the adhesive layer . The optical film sheet that has reached the bonding position is bonded to the corresponding bonding surface of the panel conveyed to the special bonding position along the conveying path by the bonding mechanism having a pair of bonding rollers. When this is a liquid crystal panel, optical film sheets containing polarizing films are placed on both sides of the liquid crystal panel so that the absorption axis becomes a cross-polarization relationship to produce a laminated body of an optical display device laminated in sequence.

On the other hand, in recent years, in optical display devices, miniaturization, thinning, and weight reduction have progressed. As a result, it is required not only to narrow the frame surrounding the liquid crystal display area, that is, to narrow the frame, but also to have no frame.化. As a method to meet this requirement, for example, as described in Patent Document 2, it is proposed to initially bond an optical film sheet larger than the liquid crystal panel to one side of the liquid crystal panel, and remove the end of the liquid crystal panel from the end of the liquid crystal panel. The remaining part of the exposed optical film sheet is cut away along the end of the liquid crystal panel, thereby forming a liquid crystal panel in which the optical film sheet is bonded on one side. Next, a liquid crystal panel with an optical film sheet laminated on one side, an optical film sheet larger than the liquid crystal panel on the other side, and the remaining part of the optical film sheet exposed from the end of the other side of the liquid crystal panel Cutting along the end of the liquid crystal panel, thereby forming a laminated body manufacturing technology of an optical display device that narrows the frame of the liquid crystal display area.

In Patent Document 2, the process of cutting off the remaining part is performed in a series of manufacturing equipment. Specifically, the remaining parts of the optical film sheets that are sequentially laminated on both sides of the liquid crystal panel in the manufacturing device are laminated in a state of being exposed from all four sides of both sides of the liquid crystal panel each time as the slave In the optical display device obtained as a finished product of the manufacturing device, all the remaining parts of the four sides are cut from both sides of the liquid crystal panel along the ends of both sides of the liquid crystal panel, and the optical film sheet becomes a laminate of the size corresponding to the bonding surface.

In another example, Patent Document 3 or Patent Document 4 proposes a production system in which an optical film sheet is exposed and bonded on only one side of a liquid crystal panel, and the optical film sheet is bonded on the other side of the liquid crystal panel without exposing the optical film sheet. Among them, the remaining part that is only exposed from one side of the liquid crystal panel and bonded is performed by the cutting process of a continuous production system as in the case of Patent Document 2.

Specifically, the remaining part of the optical film sheet bonded to one side of the liquid crystal panel is laminated in a state exposed from all four sides of the liquid crystal panel, as an optical display device obtained from the finished product of the production system, because it will be pasted The remaining part of the optical film sheet bonded to one side of the liquid crystal panel is cut away along the end of the liquid crystal panel, and on the other hand, the optical film sheet bonded to the other side of the liquid crystal panel is bonded so as not to be exposed, so The optical film sheets on both sides of the liquid crystal panel each have a size corresponding to the bonding surface of the liquid crystal panel, and become the same laminate as in the case of Patent Document 2.

The laminated body of the optical display device, the absorption axis of the polarizing film of the optical film sheet laminated on both sides of the liquid crystal panel is bonded along the reference line (alignment mark) so as to become the orthogonal polarization relationship in order to realize the optical The light switch function of the display device. The polarizing film of the optical film sheet also includes a display area, which has the size of an area on or beyond the black matrix inside the liquid crystal panel.

The laminate structure of the optical display device, as shown in the schematic view of FIG. 2, is composed of glass substrates that separate color filters on both sides of the liquid crystal at least, which becomes the CF side member on the visual side 51 of the liquid crystal panel. , And a member on the non-visual side of the TFT side of the other surface 52 of the liquid crystal panel including a light distribution film and a glass substrate interposed by a transparent electrode. Generally, one side of the long sides of the other side 52 of the liquid crystal panel has a structure in which the terminal portion 50 with a built-in transparent electrode is provided on one side of the protrusion that protrudes more than the corresponding side of one side of the liquid crystal panel.

[The problem to be solved by the invention]

The framelessness of the optical display device is achieved by laminating the liquid crystal panel and the optical film sheet with the optical film sheet exposed from the end of the liquid crystal panel in the manufacturing method of the RTP method. The remaining part of the material exposed from the end is cut away along the end of the liquid crystal panel. However, as proposed in Patent Documents 2 to 4, in a continuous manufacturing line, when the remaining part of the periphery is cut off after being exposed from the end of the liquid crystal panel and bonded, it is necessary to precisely cut all the remaining parts. Over time, productivity dropped significantly.

Here, according to customers who have LCD panel manufacturing processes such as panel manufacturers, they will require how to cut off the remaining part of the periphery, specifically whether to cut along the end of the LCD panel, or whether to install a few centimeters The degree of freedom of exposing the belt and cutting away, and the cutting away of the remaining part of the periphery, is what the customer wants to do with another process. In response to this requirement, it is required that the optical film sheet is not exposed to the visual side of the liquid crystal panel and the remaining part of the periphery of the liquid crystal panel that is largely bonded is cut away, leaving the remaining part of the optical film to provide an optical display device Layered body.

However, in the RTP method, if you want to provide a laminate without cutting off the remaining part of the periphery of the liquid crystal panel and leaving the remaining part of the optical film sheet in a continuous production line, the liquid crystal panel and the optical film sheet After bonding the liquid crystal panel and the optical film in a state exposed from the four sides on both sides of the liquid crystal panel, in the case of an optical film sheet containing a polarizing film, in order to make the absorption axis of the polarizing film into the orthogonal polarization relationship, it is confirmed that it becomes The alignment mark of the reference point of the display area of the liquid crystal panel becomes difficult. Therefore, the alignment of the optical film sheet including the liquid crystal panel and the polarizing film becomes difficult.

All the manufacturing apparatuses and manufacturing methods of the RTP method described in Patent Documents 2 to 4, in the manufacturing process or in the production system, are exposed and bonded from the liquid crystal panel and cut off all the remaining parts of the optical film sheet as the reason The optical display device obtained from the product manufactured in this way is of course formed of a laminate without the exposed portion of the optical film sheet. In other words, this is not the above-mentioned laminated body in response to customer requirements.

In addition, the embodiments disclosed in Patent Documents 3 and 4 all disclose only that the TFT side, which is the non-visual side of the liquid crystal panel, is exposed from the four sides and the optical film sheet is laminated, and the optical film sheet is not exposed on the CF side which is the visual side. The structure of the film sheet bonding. In Patent Documents 3 and 4, it is not disclosed that the optical film sheet is exposed without exposing the optical film sheet on the TFT side which is the non-visual side of the liquid crystal panel, and then the optical film sheet is exposed on the CF side which is the visual side of the liquid crystal panel. Laminated body constructed by way of bonding. This is not the above-mentioned laminated body of the optical display device in response to customer requirements.

Another technical problem is that even if the optical film sheet is exposed on the CF side, which is the visual side of the liquid crystal panel, and the remaining part is all four sides of the laminated body of the optical display device, the customer himself goes through another process When cutting off the remaining part of the peripheral edge, it is impossible to remove the risk of damaging the terminal portion hidden in the transparent electrode on the visible side of the protrusion provided on the corresponding one side of the non-visual side of the liquid crystal panel. The present invention is achieved by challenging this technical subject. [Means to solve the problem]

The above-mentioned problem can be formed on the CF side of the liquid crystal panel by pre-bonding an optical film sheet having a width or length corresponding to the width or length of the liquid crystal panel on the TFT side of the non-visual side of the liquid crystal panel. The surface of the liquid crystal panel is solved by bonding so that the optical film sheet does not cover the terminal portion on one side of the long side of the liquid crystal panel and is exposed from the side of the long side of the liquid crystal panel.

According to the laminated body of this optical display device, the process of cutting off the remaining part of the optical film sheet laminated from the exposed liquid crystal panel can be appropriately implemented in addition to the method of manufacturing the laminated body of the optical display device. , Which can greatly improve productivity.

In addition, according to the method of the present invention, the optical film sheet that becomes the non-visual TFT side surface of the liquid crystal panel and the optical film sheet that becomes the CF side surface of the liquid crystal panel are composed of polarizing films. Only at these overlapping positions, it becomes a relationship of orthogonal polarization.

Therefore, the alignment mark of the liquid crystal panel or the edge of the liquid crystal panel can be easily read by the optical film sheet on the CF side surface on the visual side on the outer periphery of the optical film sheet on the TFT side surface on the non-visual side And so on, can realize the process of cutting off the remaining part correctly.

Furthermore, when assembling the optical display device, the optical film sheet is laminated so as to be exposed from the side of the long side of the liquid crystal panel on the surface of the CF side which is the viewing side, so that the viewing side can be laminated. Borderless.

As one aspect of the present invention, although a part of the process is repeated, the processes (a) to (g) of FIG. 4 are shown, and the operations of the flowcharts (i) to (viii) of FIG. 5 corresponding thereto are shown.

The present invention is based on the first position adjustment process A1 that is adjusted so that the center line 500 of the liquid crystal panel 5 including the processes (a) to (e) coincides with the center line 600 of the conveyance path 30 of the liquid crystal panel 5, including the process ( e) The first position detection process B1 of the first optical film sheet 10 and the processes (f) and (g) included in the center line 500 of the liquid crystal panel 5 and support from the first optical film laminate After adjusting the position between the center lines 700 of the first optical film sheet 10 of the first carrier film 2 sent by the roller R1, the first bonding process of bonding the first optical film sheet 10 on one side 51 of the liquid crystal panel 5 C1 constitutes.

In the first position adjustment process A1 including the processes (a) to (e), it is assumed that the liquid crystal panel 5 is transported at the first attaching position 101 with a deviation from the center line 600 of the transport path 30. Processes (b) and (c) correspond to the operation of flow chart (i), temporarily stop the liquid crystal panel 5 transported in such a deviation state, and then, for example, actuate the position adjustment mechanism 70 shown in FIG. 3 for adjustment The center line 500 of the liquid crystal panel 5 is corrected so that it is located at the first temporary reference position α1 that coincides with the center line 600 of the conveyance path 30.

Process (d) corresponds to the operation of (ii). Here, the operation of the position adjustment mechanism 70 is released, and the position-adjusted liquid crystal panel 5 is sucked and fixed by, for example, the alignment mechanism 80 shown in FIG. 3. In FIG. 4, the first temporary reference position α1 and the first reference position β1 represent: the first temporary reference position α1 is a correction position that makes the center line 500 of the liquid crystal panel 5 coincide with the center line 600 of the conveyance path 30, and the first The reference position β1 is the position where the liquid crystal panel is read by the panel detection mechanism 150 and the corrected position is added. These are the actions included in project (e).

Process (e) corresponds to the operation of (iii). First, the panel detection mechanism 150 reads the reference point 53 of the alignment mark of the liquid crystal panel 5 and makes it match the first reference information preset in the panel detection mechanism 150 54 For comparison, the liquid crystal panel 5 is adjusted to the first reference position β1. The process (e) also corresponds to the action of (iv) to establish a connection with the readjustment of the liquid crystal panel 5. As shown in FIG. 3, at the first attaching position 101, for example, a sheet detection mechanism 90 is used for inspection. The position of the first optical film sheet 10 is shown.

The first location detection process B1 formed by the connected process (e), and then, the same corresponds to the actions (v) and (vi), that is, the actions of the control device 550, as shown in the explanatory diagram of FIG. 8 As shown, the operation of (v) is to calculate the amount of deviation between the position of the first optical film sheet 10 detected by the sheet detection mechanism 90 and the position of the liquid crystal panel 5 after being readjusted to the first reference position β1 The operation of δ, (vi) is as shown in the explanatory diagram of FIG. 9, the amount of deviation δ is added so as not to cover the terminal portion 50 on one side of the long side of the liquid crystal panel 5, and the length of the liquid crystal panel 5 The adjustment amount y1 of the first optical film sheet 10 adjusted so that the other side of the side is exposed, and the first related position information 55 is calculated.

With respect to the liquid crystal panel 5 conveyed from the upstream side to the process (a) from the center line 600 of the conveying path 30 in a deviated state, the position adjustment mechanism 70 is performed as the initial operation shown in the flowchart (i). The state of deviation is corrected to the position adjustment of the first temporary reference position α1.

The position-adjusted liquid crystal panel 5 is positioned at the first reference position β1 as follows. At this position, as the operation (ii), the liquid crystal panel 5 is sucked and fixed by the positioning mechanism 80. Also as the action of (iii), the liquid crystal panel 5 that is in a suction-fixed state by corresponding to the first reference information 54 preset in the panel detection mechanism 150 is then finely adjusted to the first reference position β1. Similarly, as the operation (iv), the first optical film sheet 10 is detected by the sheet detection mechanism 90. Following the same operations as (v) and (vi), the relative position information between the detected position of the first optical film sheet 10 and the liquid crystal panel 5 readjusted to the first reference position β1 is displayed in the control device 550 , Calculated as the first related position information 55.

The first lamination process C1, including the processes (f) and (g) to which it is connected, corresponds to the actions shown in the flowcharts (vii) and (viii), and it is appropriate to select the process (vii) corresponding to the process (f) The action should be carried out at that location. For example, it can be performed at the first reference position β1. This can also be performed at the first attaching position 101. Alternatively, it may be performed at the first attaching adjustment position γ1 located between these two positions. In the process (f), it is assumed that it will be implemented at the first sticking adjustment position γ1. In this case, the process (f) is the operation shown in the flowchart (vii) at first, and the liquid crystal panel 5 adjusted to the first reference position β1 is transported to the first attaching adjustment position γ1. Next, the liquid crystal panel 5 is at the first attachment adjustment position γ1, and based on the first related position information 55 calculated by the control device 550, the center line 500 of the liquid crystal panel 5 is from the center line 700 of the first optical film sheet 10 from The center line 700 performs the sticking adjustment of the first optical film sheet 10 only by the parallel movement of the adjustment amount y1. Then, the liquid crystal panel 5 after the attachment adjustment in this manner is transported to the first attachment position 101.

The final process (g), as the action of (viii), at the first attaching position 101, as shown in FIG. 3, the first optical film peeled off from the first carrier film 2 to the liquid crystal panel 5 after attaching adjustment The sheet 10 does not cover the terminal portion 50 formed on one side of the long side of the liquid crystal panel 5, and is exposed from the other side except one side of the long side of the liquid crystal panel 5 by the exposure amount y Fit (Figure 9).

In addition, the process (f) is the operation shown in the flow chart (vii), the first optical film sheet 10 is attached and adjusted on the liquid crystal panel 5 based on the first related position information 55, can this operation be performed here? As previously described, it may be performed in advance at the first reference position β1 or may be performed at the first attaching position 101. Therefore, in the method of manufacturing the laminated body 6 of the optical display device constituted by the steps (a) to (g), of course, it is also possible to make the liquid crystal panel 5 not be attached to the adjustment position γ1 but at the first reference position β1, Or the adjustment of the liquid crystal panel 5 due to the first attaching position 101 and the first related position information 55 is attached at the same time.

Processes (i) and (j) correspond to the operation of flow chart (ix). The liquid crystal panel 5 transported from the center line 700 of the transport path 30 by the deviation λ is temporarily stopped, for example, the position adjustment mechanism 70 is activated to correct the deviation λ from the center line 700 of the conveying path 30 of the liquid crystal panel 5, and then the terminal 50 on one side of the preset long side is not covered, and only from the long side of the liquid crystal panel 5 The adjustment amount y1 of the first optical film sheet 10 adjusted so that one side of the side and the other side are exposed, move the center line 500 of the liquid crystal panel 5 in parallel from the center line 600 of the conveying path 30, and adjust the position to the second temporary reference Location α2.

Process (k) corresponds to the operation of flowchart (x). Here, the operation of the position adjustment mechanism 70 is released, and the position-adjusted liquid crystal panel 5, for example, is sucked and fixed by the alignment mechanism 80 shown in FIG. 3 . In FIG. 6, the second temporary reference position α2 and the second reference position β2 indicate that: the second temporary reference position α2 is the amount of deviation λ corrected from the center line 700 of the conveying path 30 of the liquid crystal panel 5, and then the liquid crystal panel The center line 500 of the conveying path 30 is a correction position that is moved in parallel by the adjustment amount y1 minute from the center line 600 of the conveying path 30. The second reference position β2 is the position where the liquid crystal panel is read by the panel detection mechanism 150, plus the correction. Position. These are the actions included in project (1).

Process (l) also corresponds to the action of (xii) to establish a connection with the readjustment of the liquid crystal panel 5. As shown in FIG. 3, at the first attaching position 101, for example, the sheet detection mechanism 90 detects The position of the first optical film sheet 10 is shown.

The second location detection project B2 formed by the connected project (1), and then, the same corresponding to the actions (xiii) and (xiv), as shown in the explanatory diagram of Figure 8, the action of (xiii) is Calculate the deviation λ between the position of the first optical film sheet 10 detected by the sheet detection mechanism 90 and the position of the liquid crystal panel 5 after adjustment to the second reference position β2, and the action of (xiv) is as As shown in the explanatory diagram of FIG. 9, the deviation amount λ is added so as not to cover the terminal portion 50 on one side of the long side of the liquid crystal panel 5, and to be exposed from the side other than the side of the long side of the liquid crystal panel 5. The adjustment amount y1 of the first optical film sheet 10 adjusted in such a manner as to calculate the second related position information 56.

The positions of the processes (h) to (l) in FIG. 6 where the present invention is implemented, specifically, the second temporary reference position α2 of the processes (i) and (j) and the second reference of the processes (k) and (l) The position β2, as shown in FIG. 3, corresponds to the left end position where the panel detection mechanism 150 is installed. With respect to the liquid crystal panel 5 transported from the center line 600 of the transport path 30 from the upstream side to the process (h) in a deviated state, it is corrected by the position adjustment mechanism 70 as the initial operation shown in the flowchart (ix) The deviation state of the liquid crystal panel is adjusted in parallel movement only by the preset adjustment amount y1 minute.

The position-adjusted liquid crystal panel 5 is positioned at the second reference position β2 as follows. At this position, as the action (x), the liquid crystal panel 5 is sucked and fixed by the positioning mechanism 80. Also as the action of (xi), the liquid crystal panel 5 in the suction-fixed state by corresponding to the second reference information 56 preset in the panel detection mechanism 150 is finely adjusted to the second temporary reference position α2. Similarly, as the operation (xii), the first optical film sheet 10 is detected by the sheet detection mechanism 90. Then, as the actions (xiii) and (xiv), the relative position information between the position of the detected first optical film sheet 10 and the position of the liquid crystal panel 5 readjusted to the second temporary reference position α2 is controlled in In the device 550, it is calculated as the second related position information 57.

The second bonding project C2, which includes the projects (m) and (n) to which it is connected, corresponds to the actions of the flowcharts (xv) and (xvi). It is appropriate to select the action requirements corresponding to the (xv) of the project (m) Implement at that location. For example, it can be performed at the second reference position β2. This can also be performed at the first attaching position 101. Alternatively, it may be performed at the second attaching adjustment position γ2 located between these two positions. Process (m), here, it is planned to be implemented at the second sticking adjustment position γ2. In this case, the process (m) is the first operation shown in the flowchart (xv), and the liquid crystal panel 5 adjusted to the second reference position β2 is transported to the second attaching adjustment position γ2. Next, the liquid crystal panel 5 is at the second attachment adjustment position γ2, based on the calculated second related position information 57, so that the center line 500 of the liquid crystal panel 5 is parallel to the center line 700 of the first optical film sheet 10, 1 The optical film sheet 10 is attached and adjusted. Then, the liquid crystal panel 5 after the attachment adjustment in this manner is transported to the first attachment position 101.

In addition, the process (m) is the operation shown in the flowchart (xv), and the liquid crystal panel 5 is attached and adjusted to the first optical film sheet 10 based on the second related position information 57. Is this operation possible? As previously described, it may be performed in advance at the second reference position β2 or may be performed at the first attaching position 101. Therefore, in the method of manufacturing the laminated body 6 of the optical display device constituted by the steps (h) to (n), it is of course possible to make the liquid crystal panel 5 not go through the second attaching adjustment position γ2 but at the second reference position. β2, or the adjustment of the liquid crystal panel 5 caused by the first attaching position 101 and the second related position information 57 are attached at the same time.

The liquid crystal panel 5 used in the present invention can be clearly seen from the schematic diagram of FIG. 2 that the first optical film sheet 10 and the second optical film sheet 10 are formed on one side 51 of the liquid crystal panel 5 on the visual side and the other side 52 on the non-visual side. 2 The polarizing film of the optical film sheet 20 is bonded so that the absorption axis becomes the relationship of orthogonal polarization through an optical compensation film or the like.

The laminate 6 of the optical display device manufactured by the present invention is preliminarily bonded to one side of the liquid crystal panel 5 in a state where the second optical film sheet 20 is not exposed from the other surface 52 on the TFT side of the liquid crystal panel 5 51, that is, on the CF side, the first optical film sheet 10 is not covered with the terminal portion 50 on one side 521 of the protrusion 520 on the TFT side, and only from the long side of the liquid crystal panel 5 The adjustment amount y1 of the first optical film sheet 10 adjusted so that the other side of the one side is exposed is exposed again, so that only the exposed amount y shown in FIG. 9 is bonded together. Therefore, on the one surface 51 of the liquid crystal panel, the area of the first optical film sheet 10 bonded so as to be exposed from the other side except the one side is usually a transparent area.

In the case of the laminated body 6 of the optical display device manufactured in this way, the first optical film sheet 10 is bonded so as not to cover the terminal portion 50 formed on the liquid crystal panel 5, and is bonded to the optical film sheet to cover the liquid crystal panel 5. Compared with the conventional laminated body bonded by the terminal part 50, the remaining part of the first optical film sheet covering the terminal part 50 does not need to be cut and removed, and there is no need to worry about damaging the terminal part 50.

In one aspect or other aspects, the present invention provides a method of manufacturing the laminated body 6 of an optical display device. In one of the embodiments, as shown in the second bonding device 200 of FIG. 1, in the pretreatment process on the upstream side of the device 1 that implements the method, it has a width or length corresponding to the other side 52 of the liquid crystal panel 5. The second optical film sheet 20 having a width or length of φ is sent out from the roller R3 of the second optical film laminate of the continuous film plate in a state of being continuously supported by the second carrier film 3 by the adhesive layer. At this time, the second optical film sheet 20 is peeled from the second carrier film 3 of the continuous film plate together with the adhesive layer, and is sent to the second attaching position 201. Here, the liquid crystal panel 5 sucked and fixed by the second alignment mechanism 81 is transported to the second attaching position 201, and on the other side 52 of the liquid crystal panel 5, the second optical film sheet 20 is not exposed from the other side 52 The way is pre-fitted.

In one embodiment, the liquid crystal panel 5 in which the second optical film sheet 20 is pre-attached to the other side 52 of the liquid crystal panel 5, as shown in FIG. 1, is fixed by suction by the second alignment mechanism 81 In the state, it is transported to the second attaching position 201, where the suction and fixation of the second positioning mechanism 81 is released. After that, the liquid crystal panel 5 is transported to the reversing rotation unit 300 on the transport path 30 with the long side as the front end surface. Then, the liquid crystal panel 5 is rotated 90 degrees by a rotating mechanism not shown in the figure in the reversal rotation process, so that the short side of the liquid crystal panel 5 is inverted by the reversing mechanism not shown in the figure. As a front end surface, it is conveyed to the 1st bonding apparatus 100 along the conveyance path 30. The laminated body 6 manufactured by implementing the process of this method is conveyed to downstream processes, such as an inspection process.

In the first bonding device 100 of one embodiment, the second optical film sheet 20 has a width smaller than the width of the side 51 of the liquid crystal panel 5 that has been bonded to the other side 52 of the liquid crystal panel in the pretreatment process. The roller R1 of the first optical film laminate of the continuous film plate with a large width is sent out. The first optical film laminate is configured in a state where the first optical film sheet 10 is continuously supported on the first carrier film 2 of the continuous film plate by an adhesive layer. At this time, the first optical film sheet 10 peeled from the first carrier film 2 of the continuous film plate taken up by the roller R2 and the adhesive layer by the peeling mechanism 60 is sent to the first attaching position 101. Here, the first optical film sheet 10 does not cover the terminal portion 50 formed on one side of the long side of the liquid crystal panel 5 on the side 51 of the liquid crystal panel 5 that is conveyed to the first attachment position 101. And it is bonded so that it may be exposed from the side other than the one side of the long side of the liquid crystal panel 5. Thereby, since the first optical film sheet 10 and the second optical film sheet 20 bonded to both sides of the liquid crystal panel are formed as a polarizing film together, the absorption axes are in a relationship of orthogonal polarization to each other. In addition, in the present invention, the width of the first optical film laminate may be the same as or smaller than the width of one side of the liquid crystal panel, and the width of the first optical film laminate may be the same as the width of one side 51 of the liquid crystal panel 5. At this time, the adjustment amount y1 shown in FIG. 9 is the same as the exposure amount y, the width of the first optical film laminate is smaller than the width of the one surface 51 of the liquid crystal panel 5, and the adjustment amount y1 is greater than the exposure amount y.
