Abstract

PROBLEM TO BE SOLVED: To provide a glass film laminate which is improved in handleability of a glass film while preventing damage to the glass film.SOLUTION: The glass film laminate 1 includes: a support film 2; an adhesive layer 3 attached entirely to one main surface of the support film 2; a glass film 4 bonded to the support film 2 through the adhesive layer 3; an end film 5 connected to each of longitudinal ends of the glass film 4 being extended along the longitudinal direction of the glass film 4; and a first tape member adhered to the glass film and the each of the end films. Since the glass film 4 and the end films 5 are connected in the longitudinal direction of both, and the first tape members 6 are adhered to the main surfaces of both, the risk of cracking the end of the glass film 4 near the boundary with the end film 5 is minimized, and the glass film 4 is thus prevented from being damaged when pulling the glass film 4 by the end film 5.

Description

  The present invention relates to a glass film laminate in which a glass film is laminated on a support film via an adhesive layer, a glass film laminate roll formed by winding up the glass film laminate, and a glass film laminate on the glass film. The present invention relates to a glass film laminate with pixels for a color filter in which pixels of a plurality of colors are arranged, and a method for producing a glass film laminate. In particular, the present invention is a glass film laminate, a glass film laminate roll, and a glass film laminate with pixels for color filters, which can prevent the glass film from being damaged in the manufacturing process and can improve the handleability of the glass film. And a method for producing a glass film laminate.

  In general, glass plates have been conventionally used for electronic displays, architecture, furniture decoration, electronic devices, semiconductor devices, body members, and the like. Among these, in color filters used in electronic displays such as liquid crystal displays, electronic paper, and organic EL displays, a sheet-like glass plate is generally used as a substrate, and a plurality of colors are used on the glass plate. Pixels are formed in a pattern to produce a color filter. Further, a sheet-like glass plate is also used for a TFT substrate or an electrode substrate, an organic EL display element substrate, a solar cell, or the like which is a counter substrate of a color filter.

  By the way, with the recent progress of glass manufacturing technology, a thin glass film having a thickness of about 100 μm has been manufactured. Since this glass film is sufficiently thin, it has flexibility and can be wound into a roll. For example, when this glass film is used for a substrate of a color filter, a color filter can be continuously produced by drawing out the glass film by a desired length from a roll wound with the glass film. Production efficiency can be improved compared to the case of using a glass plate. However, since this glass film is thin, its impact resistance is inferior, and there is a problem that it is easily damaged during the manufacturing process. In particular, when a glass film wound up in a reel shape is fed out, the starting end of the glass film is easily damaged.

  As a countermeasure for such a problem, in Patent Document 1, a resin film is attached to the starting end portion of the glass film, and when the glass film is unwound, the resin film is at the head, and the glass film is pulled to pull the glass film. We are trying to prevent damage.

JP 2010-132350 A

  However, in patent document 1, it winds up in roll shape with the glass film exposed, and it is easy to produce a damage | wound on the surface of a glass film. Patent Document 1 also describes a modification in which the entire surface of the glass film is sandwiched between resin films, but once the surface of the glass film is covered with the resin film, the resin film is not damaged. It becomes difficult to peel off. Therefore, when it is necessary to expose the glass film during the manufacturing process, as in the case of producing a color filter by forming pixels directly on the glass film, the surface of the glass film is replaced with a resin film in the previous process. If it covers, the resin film must be peeled off, and at that time, the surface of the glass film may be damaged.

  The present invention has been made in view of the above-described problems, and its purpose is to prevent damage to the glass film while improving the handleability of the glass film, the glass film laminate roll, and the color. It is providing the glass film laminated body with a pixel for filters, and the manufacturing method of a glass film laminated body.

In order to solve the above problems, one embodiment of the present invention includes a support film,
An adhesive layer;
A glass film bonded to the support film via the adhesive layer;
An end film connected to the longitudinal end of the glass film along the longitudinal direction of the glass film;
And a first tape member that is adhered to the glass film and the end film.

Moreover, the other one aspect | mode of this invention WHEREIN: In the glass film laminated body roll formed by winding up a glass film laminated body,
The glass film laminate is
A belt-like support film;
An adhesive layer;
A glass film bonded to the support film via the adhesive layer;
An end film connected to the longitudinal end of the glass film along the longitudinal direction of the glass film;
A glass film laminate roll comprising: the glass film and a first tape member adhered to the end film.

Another embodiment of the present invention includes a glass laminate and a plurality of color pixels for a color filter disposed on the glass laminate,
The glass laminate is
A support film;
An adhesive layer;
A glass film bonded to the support film via the adhesive layer;
An end film connected to the longitudinal end of the glass film along the longitudinal direction of the glass film;
A first tape member adhered to the glass film and the end film,
The color filter is characterized in that the pixels of the plurality of colors are arranged on a main surface opposite to a main surface to which the first tape member is adhered, out of two opposing main surfaces of the glass film. Provided is a glass film laminate with a pixel.

  According to this invention, since a glass film and a support film are joined via an adhesion layer, even if a glass film is thin, the impact resistance of a glass film becomes high. Moreover, if the support film is thinned, the flexibility of the glass film is not impaired. Further, since the first tape member is adhered to the glass film and the end film, the glass film can be firmly fixed to the end film.

Sectional drawing of the glass film laminated body 20 with a pixel for color filters 10. FIG. Sectional drawing of the glass film laminated body by one comparative example.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view showing a cross-sectional structure along the longitudinal direction of a glass film laminate 1 according to an embodiment of the present invention. A glass film laminate 1 in FIG. 1 includes a support film 2, an adhesive layer 3 provided on the entire main surface of the support film 2, a glass film 4 bonded to the support film 2 via the adhesive layer 3, An end film 5 connected to the front end 4a and the rear end 4b of the glass film 4 along the longitudinal direction of the glass film 4, and a first tape member 6 adhered to the glass film 4 and the end film 5 The second tape member 7 adhered to at least the support film 2 and the first tape member 6, and the glass film on the surface opposite to the adhesive surface between the first tape member 6 and the end film 5 4 and the third tape member 8 adhered to the end film 5.

  Although FIG. 1 shows a structure in which the end film 5 is connected to the front end 4 a of the glass film 4, the end film 5 is also connected to the rear end 4 b of the glass film 4. The end film 5 may be referred to as a lead on the front end part 5a side and may be referred to as an end on the rear end part 5b side. In this specification, the front-end | tip part 2a and the rear-end part 2b of the longitudinal direction of the support film 2, the front-end | tip part 3a and the rear-end part 3b of the longitudinal direction of the adhesion layer 3, the front-end | tip part 4a of the longitudinal direction of the glass film 4, and The rear end portion 4b is generically called a longitudinal end portion.

  The glass film laminate 1 in FIG. 1 is excellent in flexibility, and is wound by winding the end film 5 on the lead side around the core and winding up the glass film 4 with the support film 2 sequentially. be able to. Details of the method for producing this roll will be described later.

  The support film 2 is made of a flexible plastic, and is used to reinforce the glass film 4 by compensating for weakness against impact, local pressure, and strain on the glass film 4. When the glass film 4 is rolled up in a state where foreign matter is adhered to the single glass film 4, local impact or pressure is applied to the glass film 4 due to the presence of the foreign matter, or the glass film 4. There is a high risk that the glass film 4 will be damaged due to this.

  Therefore, in the present embodiment, the support film 2 is bonded to the glass film 4 to increase the impact strength and prevent the glass film 4 from being damaged. Moreover, even if it is a case where the glass film 4 is cracked by bonding the support film 2 to the glass film 4, scattering of glass fragments or the like can be prevented.

  In the glass film laminate 1 of FIG. 1, the front end portions 2 a and 3 a of the support film 2 and the pressure-sensitive adhesive layer 3 are disposed inside the front end portion 4 a and the rear end portion 4 b of the glass film 4. That is, neither the adhesive layer 3 nor the support film 2 is disposed on the top surfaces of the front end portion 4a and the rear end portion 4b of the glass film 4.

  One end 6a in the longitudinal direction of the first tape member 6 is disposed between the longitudinal tips 2a, 3a of the support film 2 and the adhesive layer 3 and the longitudinal tip 4a of the glass film 4, and The other end 6 b in the longitudinal direction of one tape member 6 is disposed on the end film 5. The first tape member 6 is adhered to the bonding surface of the glass film 4 with the adhesive layer 3 and one main surface of the end film 5.

  The second tape member 7 is adhered to at least the support film 2 and the first tape member 6. More specifically, the second tape member 7 includes a main surface different from the main surface on which the pressure-sensitive adhesive layer 3 is provided, and one side surface connected to the main surface, and the first tape member. Among the two opposing main surfaces 6, the main surface different from the main surface adhered to the glass film 4 and the end film 5, one side surface connected thereto, and one main surface of the end film 5 are adhered.

  FIG. 1 shows an example in which the second tape member 7 is adhered to the end film 5, but the tip 7 a of the second tape member 7 is disposed on the upper surface of the first tape member 7. May be. In this case, the second tape member 7 is adhered only to the support film 2 and the first tape member 6 and is not adhered to the end film 5.

  Although it is assumed that the adhesive force of the first to third tape members 6 to 8 is higher than the adhesive force of the adhesive layer 3, the adhesive force of the same degree may be used.

  In addition, the first tape member 6 is essential, but the second tape member 7 and the third tape member 8 may be omitted. However, as will be described later, when the first tape member 6 is peeled for the purpose of peeling the support film 2, the third tape member 8 is used to maintain the connection between the glass film 4 and the end film 5. Is mandatory.

  The glass film laminate 1 shown in FIG. 1 can be used to produce a color filter for a display device such as a liquid crystal display device or an EL display device.

  FIG. 2 is a cross-sectional view showing an example of the cross-sectional structure of the color filter 10. The color filter 10 in FIG. 2 includes a glass film 4 and red pixels 11, green pixels 12, and blue pixels 13 provided on the glass film 4. The glass film 4 in FIG. 2 is different from that in FIG.

  Usually, a black matrix 14 patterned in a matrix shape is provided on the glass film 4, and each pixel 11, 12, 13 is formed in each opening defined by the black matrix 14 on the glass film 4. Has been. That is, in each opening of the black matrix 14, the red pixel 11, the green pixel 12, and the red (R) pixel photosensitive material, the green (G) pixel photosensitive material, and the blue (B) pixel photosensitive material. And the blue pixel 13 is formed. The arrangement of the pixels 11, 12, and 13 is not shown, but may be a known arrangement such as a stripe arrangement, a delta arrangement (triangle arrangement), a square arrangement (four pixel arrangement), or the like. Thus, one display pixel on the screen is formed by three adjacent pixels having different colors. Further, yellow pixels (not shown) or the like may be added to form four or more color pixels. As a photosensitive material for forming each pixel 11, 12, 13, a pigment dispersion type photosensitive resin composition containing a pigment of each color, a solvent, and a bonding resin (binder) can be used. As the photosensitive material for forming a photosensitive resin composition, a photosensitive resin composition in which a black pigment having a light shielding property is dispersed can be used.

  Further, as shown in FIG. 1, these pixels 11, 12, and 13 are covered with a protective layer 15. A transparent electrode film 16 made of indium tin oxide (ITO) is formed on the protective layer 15.

  Such a color filter 10 is combined with, for example, a liquid crystal element including a switching element such as a TFT and a liquid crystal layer arranged corresponding to each of the pixels 11, 12, and 13, and a surface light source, and a liquid crystal display (LCD) ) Or electronic paper. In this configuration, the liquid crystal is controlled by the switching element to function as a shutter, and emits light from the surface light source only through pixels of a desired color. In this way, a color image is displayed on the screen.

  The glass film 4 in the color filter 10 of FIG. 2 is the glass film 4 of the glass film laminated body 1 shown in FIG. 1, and the support film 2 is joined via the adhesive layer 3 of the glass film 4 of FIG. The surface side opposite to the side corresponding to the surface corresponds to the surface side on which the pixels 11, 12, 13 and the black matrix 14 of the glass film 4 of FIG. 2 are provided.

  Thus, the glass film 4 in the glass film laminated body 1 of FIG. 1 can be used as a board | substrate which produces the color filter 10 shown, for example in FIG.

  Next, the material of each member of the glass film laminated body 1 of FIG. 1 is demonstrated.

  Examples of the material for the support film 2 include polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyethersulfone (PES), polyimide (PI), polyetheretherketone (PEEK), polycarbonate (PC), and polyethylene. (PE), polypropylene (PP), polyphenylene sulfide (PPS), polyetherimide (PEI), cellulose triacetate (CTA), cyclic polyolefin (COP), polymethyl methacrylate (PMMA), polysulfone (PSF), polyamideimide (PAI) ), Synthetic resins such as nobornene resins and allyl ester resins. Among these, PET, PEN, and COP are preferable because of characteristics such as transparency and flexibility. The thickness of the support film 2 is 3 to 200 μm, preferably 5 μm to 200 μm. This makes it possible to ensure the strength necessary for reinforcing the glass film 4 and to wind the glass film laminate 1 having the support film 2 in a roll shape.

  The material of the adhesive layer 3 is not particularly limited as long as it has flexibility, but an acrylic or styrene resin material is preferable. Moreover, it is preferable that the thickness of the adhesion layer 3 is 5-200 micrometers. Thereby, while being able to ensure sufficient adhesive force for joining the support film 2 and the glass film 4, the fall of the optical characteristic as the glass film laminated body 1 can be prevented. For example, a decrease in transmittance, coloring, and an increase in retardation can be prevented.

  As will be described later, in this embodiment, the glass film laminate 1 is produced using the support film 2 with the adhesive layer 3 in which the adhesive layer 3 is provided in advance on the support film 2.

  The material of the glass film 4 is not particularly limited as long as it can be formed into a film shape, but soda lime glass and alkali-free glass generally used for display applications are preferable. Of these, alkali-free glass that is colorless and has high transparency, has a low coefficient of linear thermal expansion, and is difficult to deform is preferable. Moreover, it is preferable that the thickness of the glass film 4 is 5-300 micrometers. This makes it possible to stably manufacture the glass film 4, to have a minimum strength in handling, and to wind up the glass film laminate 1 having the glass film 4 in a roll shape. .

  The end film 5 does not necessarily have the same thickness as the glass film 4, but as shown in FIG. 1, the end film 5 and the glass film 4 are connected to each other in the longitudinal direction. Since the second tape members 6 and 7 are adhered to each other, if there is a large difference in thickness, a step is formed, and the adhesive force of the first and second tape members 6 and 7 becomes weak, or glass The end of the film 4 is easily damaged. Therefore, preferably, the difference in thickness between the end film 5 and the glass film 4 is made as small as possible.

  The material of the end film 5 may be the same material as the support film 2, for example, polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyethersulfone (PES), polyimide (PI), polyetheretherketone. (PEEK), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyphenylene sulfide (PPS), polyetherimide (PEI), cellulose triacetate (CTA), cyclic polyolefin (COP), polymethyl methacrylate (PMMA) And synthetic resins such as polysulfone (PSF), polyamideimide (PAI), nobornene resin, and allyl ester resin. The end film 5 is connected to both ends of the glass film 4 and does not require transparency.

  The first to third tape members 6 to 8 are made by, for example, applying a silicone-based adhesive to a Kapton (registered trademark) polyimide film, and the adhesive strength thereof is higher than the adhesive strength of the adhesive layer 3. The film thicknesses of the first to third tape members 6 to 8 are 1 μm to 200 μm, preferably 30 μm to 100 μm, and more preferably about 50 μm.

  It is a precondition that the outer sizes of the first to third tape members 6 to 8 do not protrude from the ends of the support film 2, the glass film 4, and the end film 5, which are objects of adhesion. More specifically, the widths of the first to third tape members 6 to 8, that is, the lengths in the direction perpendicular to the longitudinal directions of the glass film 4 and the end film 5 are the glass film 4 and the end film 5. Is less than the width in the short direction. In addition to this, since the second tape member 7 is also adhered to the upper surface of the support film 2 and the side surface continuous therewith, the width of the second tape member 7, that is, the direction orthogonal to the longitudinal direction of the support film 2. Is less than the width of the support film 2 in the short direction. The length of the first to third tape members 6 to 8 in the longitudinal direction is such that when the end film 5 is grasped and pulled out from the glass film laminate roll, the first to third tape members 6 to 6 are held by the grip force. It is necessary to have a length sufficient to secure an adhesive strength that does not peel off 8. In addition, the first to third tape members 6 to 8 can be applied not only to a film on which an adhesive material has been previously applied, but also to various other base materials, and base materials such as film members and sheet members. An adhesive material may be sandwiched between the glass film 4 and the end film 5. That is, the specific material and form of the first to third tape members 6 to 8 are not limited as long as the base material can be firmly adhered to the glass film 4 and the end film 5.

  Next, the manufacturing apparatus of the glass film laminated body 1 shown in FIG. 1 is demonstrated. This manufacturing apparatus is also called a laminator. FIG. 3 is a diagram showing a schematic configuration of a manufacturing apparatus for the glass film laminate 1. The manufacturing apparatus of FIG. 3 includes a support film supply unit 21, a glass film supply unit 22, an end film supply unit 23, a nip roller 24, and a winding unit 25.

  The support film supply unit 21 feeds out the support film 2 with the adhesive layer 3 by a desired length from the roll 21a around which the support film 2 with the belt-like adhesive layer 3 is wound.

  The glass film supply unit 22 unwinds the glass film 4 by a desired length from a roll 22a around which the belt-shaped glass film 4 is wound. The end film supply unit 23 feeds the end film 5 by a desired length from a roll 23 a around which the band-shaped end film 5 is wound.

  In the roll 21 around which the support film 2 with the adhesive layer 3 is wound, if the adhesive layer 3 is left exposed, the adhesive layer 3 is stuck to the support film 2 on the inner peripheral side, and the support film 2 cannot be fed out. Therefore, it is desirable to cover the upper surface of the pressure-sensitive adhesive layer 3 with a cover sheet, roll it up in a roll shape, feed the support film 2 and then peel off the cover sheet. In order to peel the cover sheet, a peeling part for peeling the cover sheet and a collection part for winding and collecting the peeled cover sheet may be provided adjacent to the support film supply part 21. In FIG. 3, for the sake of simplicity, the peeling portion and the recovery portion are omitted.

  In order to produce the glass film laminated body 1 of FIG. 1 using the manufacturing apparatus of FIG. 3, first, the roll 21a of the support film 2 with the adhesion layer 3, the roll 22a of the glass film 4, and the roll 23a of the end film 5 are used. Are attached to the support film supply unit 21, the glass film supply unit 22, and the end film supply unit 23, respectively.

  Subsequently, the end film 5 is fed out from the end film supply unit 23, and the front end portion 5 a of the end film 5 is moved to the vicinity of the roller of the winding unit 25.

  Subsequently, the support film 2 with the adhesive layer 3 is unwound from the support film supply unit 21 and the glass film 4 is unwound from the glass film supply unit 22 so that the front end 4a of the glass film 4 is supported as shown in FIG. The film 2 is positioned so as to protrude from the tip of the film 2. Then, the glass film 4 and the support film 2 are pressure-bonded with the nip roller 24 through the adhesive layer 3.

  Subsequently, the first tape member 6 is adhered to the upper surface of the glass film 4 and the upper surface of the end film 5. Subsequently, the second tape member 6 is adhered to the upper surface of the end film 5, the upper surface of the first tape member 6 and the side surface connected thereto, and the upper surface of the support film 2. Subsequently, the end film 5 is cut in accordance with the front end 4 a of the glass film 4. The third tape member 8 is adhered to the bottom surface of the glass film 4 and the bottom surface of the end film 5 on the side opposite to the surface of the glass film 4 bonded to the support film 2 via the adhesive layer 3. Thereby, the produced glass film laminated body 1 by which the glass film laminated body 1 of FIG. 1 is produced is wound up by the winding roll 25a, and the glass film laminated body roll 25a is completed.

  When the color filter 10 is manufactured using the glass film laminate roll 25 a described above, first, the glass film laminate 1 having the structure of FIG. 1 is drawn out from the glass film laminate roll 25 a, and the pixel is formed on the glass film 4. The photosensitive material for coating is applied, and a series of steps of drying (pre-baking), exposure, development and curing (post-baking) is repeated. Then, as shown in FIG. 2, pixels 11, 12, 13 and black matrix 14 of each color are formed on the glass film 4.

  Subsequently, a protective layer 15 covering each of the pixels 11, 12, and 13 is formed, a transparent electrode film 16 is formed on the protective layer 15, and the glass film laminated body 20 with a pixel for the color filter 10 shown in FIG. can get. Then, the support film 2, the adhesion layer 3, the edge part film 5, and the 1st-3rd tape members 6-8 are peeled from the glass film 4, and the color filter 10 shown in FIG. 2 can be obtained.

  Thus, in this embodiment, since the support film 2 is affixed to the glass film 4, the original flexibility of the glass film 4 can be maintained while improving the impact resistance of the glass film 4. The glass film laminate 1 can be wound into a roll without being damaged, and the handleability is improved. In the present embodiment, the glass film 4 and the end film 5 are connected to each other in the longitudinal direction, and both the main surfaces are adhered to the first and third tape members 6 and 8. In the vicinity of the boundary with the film 5, the glass film 4 is no longer exposed and the end of the glass film 4 is less likely to break. When the glass film 4 is pulled by the end film 5, the glass film 4 It won't hurt. More specifically, when the glass film 4 is unwound from the roll of the glass film laminate 1, the end film 5 is disposed on the front side of the glass film 4. It will be drawn out first, and the glass film 4 can be drawn out without damaging the glass film 4.

Furthermore, in this embodiment, the 2nd tape member 7 is arrange | positioned on the upper surface side of the 1st tape member 6, and this 2nd tape member 7 is attached to the support film 2, the 1st tape member 6, and an edge part. In order to adhere to the film 5, the support film 2, the glass film 4 and the end film 5 can be firmly fixed, and when the support film 2 is peeled from the glass film laminate 1, the support film 2 is not peeled directly. In addition, by peeling the second tape member 7, the support film 2 can be easily peeled together, and the support film 2 can be easily peeled without damaging the glass film 4.
By the way, in FIG. 1, the 2nd tape member 7 and the 3rd tape member 8 are not essential, and may be abbreviate | omitted. That is, the second tape member 7 and the third tape member 8 may be omitted if it is not necessary to peel the support film 3 after the glass film laminate 1 is completed.
The second tape member 7 only needs to be adhered to at least the support film 3 and the first tape member 6, and is not necessarily adhered to the end film 5.

  Based on the above description, those skilled in the art may be able to conceive additional effects and various modifications of the present invention. Accordingly, aspects of the present invention are not limited to the individual embodiments described above. Various additions, modifications, and partial deletions can be made without departing from the concept and spirit of the present invention derived from the contents defined in the claims and equivalents thereof.

  About both the glass film laminated body 1 produced using the manufacturing method of the glass film laminated body 1 by this embodiment, and the glass film laminated body 1 by the comparative example with the structure shown in FIG. It was confirmed whether or not.

  In this example, a PET film roll 21 a having a thickness of 59 μm, a width of 300 nm, and a length of 10 m was prepared as the support film 2. An adhesive layer 3 was applied on the PET film, and a cover sheet 16 was attached to the upper surface of the adhesive layer 3 in a peelable manner. Further, as the glass film 4, a roll 22a of thin glass (OA-10G manufactured by Nippon Electric Glass Co., Ltd.) having a thickness of 75 μm, a width of 300 mm, and a length of 10 m was prepared. Further, as the end film 5, a PET film roll 23a having a thickness of 125 μm, a width of 300 nm, and a length of 10 m was prepared. Further, as the first and third tape members 6 and 8, Kapton tapes having a thickness of 50 μm and a width of 300 nm were prepared.

  Subsequently, the roll 21a of the support film 2, the roll 22a of the glass film 4, and the roll 23a of the end film 5 are respectively installed at predetermined locations in the manufacturing apparatus of FIG. The paper was passed to the take-up roll 25a.

  Subsequently, the front end portion 4a of the glass film 4 and the front end portion 2a of the support film 2 are extended to the vicinity of the nip roller 24, and the front end portion 4a of the glass film 4 is more than the front end portion of the support film 2 as shown in FIG. It positions so that it may protrude, and it laminates with the nip roller 24. FIG.

  Subsequently, Kapton tape is adhered to one main surface of the glass film 4 and one main surface of the end film 5. Subsequently, the second tape member 6 is adhered to the upper surface of the end film 5, the upper surface of the first tape member 6 and the side surface connected thereto, and the upper surface of the support film 2. Then, according to the position of the front-end | tip part 4a of the glass film 4, the edge part film 5 is cut | disconnected and the Kapton tape is made to adhere to the glass film 4 and the edge part film 5 from the back surface side. Kapton tape is adhered to the rear end side of the glass film 4 in the same procedure. Thereby, the glass film laminated body 1 shown in FIG. 1 was produced.

  Then, the produced glass film laminated body 1 was wound up by the core whose diameter is 6 inches, and the glass film laminated body roll 25a was produced.

  In order to confirm the effect of this example, the present inventor produced a glass film laminate 1a according to one comparative example. FIG. 5 is a cross-sectional view showing a cross-sectional structure along the longitudinal direction of a glass film laminate 1a according to a comparative example. The glass film laminated body 1a of FIG. 5 is the glass film 4, the edge part film 5 arrange | positioned on the upper surface of the front-end | tip part 4a and rear-end side of this glass film 4, and the upper surface of the glass film 4 and the end film 5 And a tape member 6a to be adhered. In FIG. 5, only the cross-sectional structure on the front end 4 a side of the glass film 4 is illustrated, but the rear end side of the glass film 4 has a similar cross-sectional structure.

  The shapes and materials of the glass film 4 and the end film 5 in FIG. 5 are the same as the shapes and materials of the glass film 4 and the end film 5 of the above-described embodiment. The tape member 6a was also made of a Kapton tape having the same thickness and material as the first and third tape members 6 and 8 of this example.

  Since the glass film laminate 1a according to the comparative example in FIG. 5 does not have the support film 2 bonded to the glass film 4, the glass film 4 may be broken by an impact smaller than that of the present example. Further, since the end film 5 is disposed on the top surfaces of the front end 4a and the rear end of the glass film 4, even if the tape member is adhered to the glass film 4 and the end film 5, the glass film 4 A step is formed in the end film 5 and an unstable structure is obtained. Therefore, the front end 4a and the rear end 4b of the glass film 4 are particularly easily broken.

  Compared with the comparative example, the glass film laminate 1a according to the present example has the support film 2 bonded to the glass film 4, so that the impact resistance of the glass film 4 is increased and is not easily broken. Moreover, since the glass film 4 and the end film 5 are connected to each other in the longitudinal direction, the step between the two is reduced and the structure is stable, and the end of the glass film 4 is hardly broken. Furthermore, since the support film 2 can also be peeled together by peeling the 2nd tape member 7 on the support film 2 when peeling the support film 2 bonded together to the glass film 4, the glass film laminated body 1a After manufacturing, it becomes easy to peel the support film 2 without damaging the glass film 4. Furthermore, when the end film 5 is connected to the glass film 4 or the support film 2, the end film 5 and the glass film 4 or the end film 5 and the support film 2 The joint strength can be increased. These effects are never obtained in one comparative example.
