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. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass film laminated body with a pixel for a color filter provided with a plurality of color pixels and a method for producing the glass film laminated body, and in particular, a glass film capable of preventing damage to the glass film and improving handling properties. It is related with the manufacturing method of a laminated body, a glass film laminated body roll, the glass film laminated body with a pixel for color filters, and a glass film laminated body.

  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 recent advances in glass manufacturing technology, a glass film having a thickness of about 100 μm has been manufactured. Such a glass film has flexibility and can be wound into a roll. For example, when this glass film is used as a substrate for a color filter, a color filter can be continuously produced by feeding out the glass film from a roll on which the glass film is wound, and a sheet-like glass plate is used. Compared with this, production efficiency can be improved. However, since such a glass film is thin, there is a problem that impact resistance is lowered and it is damaged during the manufacturing process.

  As a countermeasure for such a problem, a glass film laminate in which a plastic film is laminated on a glass film via an adhesive layer in order to protect the glass film is known. In such a glass film laminated body, in order to protect the edge part of a glass film, the width | variety of the plastic film is made larger than the width | variety of a glass film.

  However, in this case, the adhesive layer protrudes and is exposed on both sides of the glass film. For this reason, when a glass film laminated body was wound up in roll shape, there existed a problem that the part of the glass film laminated body which mutually adjoins with the exposed adhesion layer adhered.

  On the other hand, Patent Document 1 describes that a protective sheet is detachably attached to an adhesive layer protruding from the glass film so as to overlap both sides of the glass film.

In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual ones.

(First embodiment)
First, the glass film laminated body by this Embodiment by FIG. 1, the glass film laminated body roll formed by winding up this glass film laminated body, the glass film laminated body with a pixel for color filters, and a glass film laminated body The manufacturing method will be described.

  As shown in FIG. 1, the color filter 1 in the present embodiment includes a glass film 12 and red pixels 2, green pixels 3, and blue pixels 4 provided on the glass film 12.

  Usually, a black matrix 5 patterned in a matrix shape is provided on the glass film 12, and each pixel 2, 3, 4 is formed in each opening defined by the black matrix 5 on the glass film 12. Has been. That is, in each opening of the black matrix 5, a red pixel 2, a green pixel 3 are formed by a red (R) pixel photosensitive material, a green (G) pixel photosensitive material, and a blue (B) pixel photosensitive material. And the blue pixel 4 is formed. The arrangement of the pixels 2, 3, 4 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. In addition, as the photosensitive material for forming each pixel 2, 3, and 4, 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 2, 3, and 4 are covered with a protective layer 6. A transparent electrode film 7 made of indium tin oxide (ITO) is formed on the protective layer 6.

  Such a color filter 1 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 2, 3, and 4, and a surface light source. ) 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 color filter 1 having the glass film 12 described above can be manufactured using the glass film laminate 10 having the glass film 12.

  Then, the glass film laminated body 10 in this Embodiment is demonstrated using Fig.2 (a). The glass film laminate 10 includes a support film 11 and a glass film 12 laminated on the support film 11 via an adhesive layer 13. Among these, the support film 11 is formed of a plastic having flexibility as will be described later, and is used to reinforce the glass film 12 by making up for weakness against impact, local pressurization, and strain on the glass film 12. is there. When the single glass film 12 is wound up with a foreign substance, the glass film 12 may be easily broken due to local impact, pressurization, scratches, or the like. Therefore, by bonding the support film 11 to the glass film 12, the strength can be increased and the glass film 12 can be prevented from being damaged. Moreover, even if it is a case where the glass film 12 is cracked by bonding the support film 11 to the glass film 12, scattering of glass fragments or the like can be prevented.

  The glass film 12 has a width smaller than the width of the support film 11 and the width of the adhesive layer 13. And the glass film 12 is arrange | positioned so that the support film 11 and the adhesion layer 13 may protrude from the both sides of the glass film 12. FIG. In this Embodiment shown to Fig.2 (a), the glass film 12 is arrange | positioned in the center part of the width direction (The horizontal direction with respect to the conveyance direction of each film in FIG. 3) of the support film 11 and the adhesion layer 13. As shown in FIG. Yes. In this way, the side regions 14 of the support film 11 and the adhesive layer 13 are formed on both sides of the glass film 12. In addition, as shown to Fig.2 (a), the glass film 12 is arrange | positioned in the center part of the width direction of the support film 11 and the adhesion layer 13, and it is restricted that the width | variety of each side part area | region 14 becomes equal. The width of each side region 14 may be different. That is, as long as the support film 11 and the adhesive layer 13 protrude from both sides of the glass film 12 and the side region 14 is formed, the arrangement of the glass film 12 can be arbitrary.

  A non-adhesive layer 15 obtained by transfer is provided on the adhesive layer 13 in the entire area of each of the side regions 14. This non-adhesive layer 15 is in contact with the side surface of the glass film 12 and prevents the adhesive layer 13 from being exposed over the entire side region 14. Such a non-adhesive layer 15 is obtained by transferring and adhering a non-adhesive material layer 15 a that is detachably attached to a release film 17 described later onto the adhesive layer 13.

  Next, the glass film laminated body 1a with a pixel for color filters is demonstrated using FIG.2 (b). The pixel-attached glass film laminate 1a for a color filter corresponds to an intermediate product when the color filter 1 is produced using the glass film laminate 10, and includes the glass film laminate 10 described above, A plurality of color pixels 2, 3, 4 and a black matrix 5 for color filters provided on the glass film 12 of the glass film laminate 10 are provided. Among these, each pixel 2, 3, 4 is covered with a protective layer 6, and a transparent electrode film 7 is formed on the protective layer 6. In this color filter-attached glass film laminate with a pixel 1a, the support film 11 and the adhesive layer 13 are peeled off from the glass film 12 with the non-adhesive layer 15 so that the color filter 1 shown in FIG. 1 is obtained. It has become. In addition, when using the support film 11 with a small phase difference in the color filter 1 for liquid crystal displays, the support film 11 is not necessarily peeled off, and the color filter 1 is configured with the support film 11 attached. May be. Furthermore, in a display that does not use polarized light as a display principle, such as an EL display or electronic paper, the color filter 1 may be configured with the support film 11 attached regardless of the phase difference amount. In this case, the support film 11 and the adhesive layer 13 in the side region 14 may be removed by cutting or the like with the non-adhesive layer 15.

  Next, the material of each component will be described.

  Examples of the material used for the support film 11 include 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), 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 11 is 3 to 200 μm, preferably 5 to 200 μm. This makes it possible to ensure the strength necessary for reinforcing the glass film 12 and to wind the glass film laminate 10 having the support film 11 into a roll.

  The material used for the glass film 12 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 12 is 5-300 micrometers. Accordingly, the glass film 12 can be stably manufactured, and can have a minimum strength in handling, and the glass film laminate 10 having the glass film 12 can be wound into a roll. .

  The material used for the adhesive layer 13 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 13 is 5-200 micrometers. Thereby, it is possible to secure a sufficient adhesive force for adhering the support film 11 and the glass film 12 and to prevent a decrease in optical properties as the glass film laminate 10. For example, a decrease in transmittance, coloring, and an increase in retardation can be prevented.

  The material used for the non-adhesive material layer 15a is not particularly limited as long as it can be reliably affixed to the adhesive layer 13 and can be affixed to the release film 17, but it is particularly preferable to use an acrylic resin. It is. Further, the thickness of the non-adhesive material layer 15 a is preferably smaller than the thickness of the glass film 12. In this case, the upper surface of the non-adhesive layer 15 obtained by transferring the non-adhesive material layer 15a can be disposed below the upper surface of the glass film 12. For example, in the color filter manufacturing process, exposure is performed during exposure. The mask can be prevented from sticking to the non-adhesive layer 15, and the handleability of the glass film laminate 10 can be improved. Specifically, the thickness of the non-adhesive material layer 15a is preferably 0.1 to 100 μm depending on the thickness of the glass film 12 to be used. Thus, the non-adhesive layer 15 can be stably formed by transfer, and can have a minimum strength in handling, and the glass film laminate 10 having the non-adhesive layer 15 is wound in a roll shape. Is possible.

Among them, a cover sheet (release paper) 16 is detachably attached to an adhesive layer 13 provided on one surface of the support film 11, and the support films 11 adjacent to each other in the roll of the support film 11. Are prevented from adhering to each other by the adhesive layer 13. Moreover, in the vicinity of the support film supply part 21, the peeling part 24 for peeling the cover sheet 16 from the support film 11 drawn out from the support film supply part 21, and the peeled cover sheet 16 are wound up and collected. And a collecting unit 25 for performing the above operation.

  Moreover, the non-adhesive material layer 15a is provided in one surface of the peeling film 17 so that peeling is possible. The release film 17 and the non-adhesive material layer 15a have a width larger than the width of the support film 11 and the adhesive layer 13 as shown in FIG. 4 (a), and the glass film 12 as shown in FIG. 4 (b). The non-adhesive material layer 15a can be pasted on the adhesive layer 13 over the entire area of each side region 14 even if the thickness of the side region 14 is taken into consideration. 4B, the release film 17 and the non-adhesive material layer 15a are formed so as to cover the entire surface of the glass film 12. In addition, it is not restricted to this, If the non-adhesive material layer 15a can be affixed on the adhesion layer 13 in the whole region of the side part area | region 14, the shape of the peeling film 17 and the non-adhesive material layer 15a is arbitrary. can do. For example, you may form the peeling film 17 and the non-adhesive material layer 15a so that only the both sides of the glass film 12 may be covered instead of the whole glass film 12. FIG.

  On the downstream side in the transport direction of the support film supply unit 21, the glass film supply unit 22 and the release film supply unit 23, a laminated pressing unit 26 for laminating the support film 11, the glass film 12 and the release film 17 is provided. The laminated pressing part 26 laminates and attaches the glass film 12 to the support film 11 via the adhesive layer 13, and also the non-adhesive material layer 15 a on the adhesive layer 13 in each of the side regions 14. Then, the release film 17 is attached. Thus, the intermediate body 32 before peeling shown in FIG.4 (b) is obtained. In this pre-peeling intermediate 32, the portion corresponding to the adhesive layer 13 in the non-adhesive material layer 15 a is attached to the adhesive layer 13, and the portion corresponding to the glass film 12 is attached to the glass film 12. The glass film 12 is covered without being attached.

With this peeling part 35, the peeling film 17 is peeled from the part of the non-adhesive material layer 15a affixed on the adhesive layer 13 with the part corresponding to the glass film 12 among the non-adhesive material layers 15a. In this manner, the non-adhesive layer 15 is formed by the portion of the non-adhesive material layer 15 a attached on the adhesive layer 13 in the entire area of each of the side regions 14. That is, the non-adhesive layer 15 transferred from the release film 17 is formed on the adhesive layer 13. The peeled release film 17 is wound and collected by the collecting unit 36. Thus, the glass film laminated body 10 shown in FIG.4 (c) is obtained.

  On the downstream side of the peeling part 35, a laminated body winding part 27 for winding the glass film laminated body 10 around a cylindrical core 28a is provided. In this laminated body winding part 27, the glass film laminated body roll 28 by which the glass film laminated body 10 was wound up by the core 28a is formed.

  Subsequently, the support film 11 with the adhesive layer 13 is fed out from the support film supply unit 21, the glass film 12 is fed out from the glass film supply unit 22, and the release film 17 with the non-adhesive material layer 15 a from the release film supply unit 23. Are fed out and conveyed to the stacking press part 26, respectively. At this time, the cover sheet 16 on the pressure-sensitive adhesive layer 13 fed out from the support film supply unit 21 is peeled off from the pressure-sensitive adhesive layer 13 by the peeling unit 24, wound up and collected by the collecting unit 25. In this way, the support film 11 with the adhesive layer 13 from which the cover sheet 16 has been peeled is conveyed to the laminated pressing portion 26.

  Next, in the laminated pressing part 26, the glass film 12 is laminated and attached to the support film 11 via the adhesive layer 13, and at the same time, the non-adhesive material layer on the adhesive layer 13 in each of the side regions 14. A release film 17 is attached via 15a. Thus, the intermediate body 32 before peeling shown in FIG.4 (b) is obtained.

  The obtained pre-peeling intermediate 32 is transported to the peeling portion 35, and the peeling film 35 affixes the peeling film 17 onto the adhesive layer 13 together with the portion corresponding to the glass film 12 in the non-adhesive material layer 15 a. It is peeled off from the attached non-adhesive material layer 15a, and is wound up and collected by the collecting unit 36. In this manner, the non-adhesive layer 15 is formed by the portion of the non-adhesive material layer 15 a attached on the adhesive layer 13 in the entire area of each of the side regions 14. That is, the non-adhesive layer 15 transferred from the release film 17 is formed on the adhesive layer 13, and the glass film laminate 10 shown in FIG. 4C is obtained.

  Then, the obtained glass film laminated body 10 is conveyed by the laminated body winding part 27, and is wound up by the core 28a. In this way, the glass film laminate roll 28 is formed.
