Description

  The present invention relates to a glass film laminate and a glass film laminate with pixels for a color filter in which pixels of a plurality of colors are provided on the glass film of the glass film laminate, and in particular, prevents deformation of the glass film. It is related with the glass film laminated body which can be used, and the glass film laminated body with a pixel for color filters.

  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 drawing out the glass film from a roll on which the glass film is wound (roll-to-roll). Process), production efficiency can be improved as compared with the case of using a sheet-like glass plate. 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 against such a problem, a glass film laminate in which a plastic film (transparent resin layer) is bonded to a glass film (ultra thin plate glass) is known (for example, see Patent Document 1).

JP 2008-273211 A

  However, when a strip-shaped glass film laminate in which a plastic film is bonded to a glass film is applied to a roll-to-roll process, tension is applied to the glass film laminate. In this case, since the Young's modulus is greatly different between the glass film and the plastic film, the deformation amount of the glass film and the deformation amount of the plastic film with respect to the applied tension are different, and there is a problem that the glass film is deformed. .

  In addition, when forming pixels for color filters on the glass film of the glass film laminate described above by photolithography, the pixels are formed on the glass film for the purpose of removing solvents and moisture and promoting thermal crosslinking. In general, the glass film laminate is heat-treated at a temperature of, for example, 200 ° C. or more to cure (post-bake) the pixels and then cool. However, the thin glass film does not have a rigidity capable of resisting the shrinkage force of the plastic film during cooling. For this reason, there was a problem that the glass film warps (curls) due to the shrinkage force of the plastic film.

  The present invention has been made in consideration of such points, and an object of the present invention is to provide a glass film laminate that can prevent deformation of the glass film and a glass film laminate with a pixel for a color filter. To do.

  The present invention provides a glass film laminate comprising a glass film and a metal substrate laminated on the glass film via an adhesive layer.

  In the glass film laminate described above, the metal substrate preferably has a Young's modulus of 10 GPa or more.

  Moreover, in the glass film laminate described above, the heat shrinkage rate of the metal base material is 0.05% or less after firing at 230 ° C. for 150 minutes in accordance with IPC TM650 Method 2.2.4. It is preferable.

  The present invention provides a glass film laminate comprising a glass film and a support substrate laminated on the glass film via an adhesive layer, the support substrate having a glass cloth. .

  In addition, in the glass film laminated body mentioned above, it is preferable that the said support base material is comprised with the glass containing plastic film which has the said glass cloth.

  The present invention provides a glass film laminate having a glass film and a metal substrate laminated on the glass film via an adhesive layer, and a color filter provided on the glass film of the glass film laminate. And a pixel-attached glass film laminate for a color filter.

  Embodiments of the present invention will be described below with reference to the drawings. 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, a glass film laminate and a glass film laminate with a pixel for a color filter according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 1, the color filter 1 in the present embodiment includes a glass film 11 and red pixels 2, green pixels 3, and blue pixels 4 provided on the glass film 11.

  Usually, a black matrix 5 patterned in a matrix shape is provided on the glass film 11, and each pixel 2, 3, 4 is formed in each opening defined by the black matrix 5 on the glass film 11. Has been. That is, in each opening of the black matrix 5, a red pixel 2, a green pixel 3, 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.

  These pixels 2, 3 and 4 are covered with a protective layer 6 as shown in FIG. 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 configuration in FIG. 1 is an example, and is appropriately changed depending on the type of display and the operation principle of the display element. For example, a configuration in which the black matrix 6 is not provided or a configuration in which the transparent electrode film 8 is not provided. is there.

  The color filter 1 having the glass film 11 described above can be manufactured using the glass film laminate 10 (see FIG. 2) having the glass film 11.

  Then, the glass film laminated body 10 in this Embodiment is demonstrated using FIG. The glass film laminate 10 includes a glass film 11 and a metal substrate 12 laminated on the glass film 11 via an adhesive layer 13. Among these, the metal base 12 is comprised by the metal foil formed in foil shape (or thin film shape) in this Embodiment.

  The metal substrate 12 preferably has a Young's modulus of 10 GPa or more. Thereby, the difference between the Young's modulus (50 GPa or more and 90 GPa or less) of the glass film 11 and the Young's modulus of the metal substrate 12 can be reduced. In this case, even when tension is applied to the glass film laminate 10 in the roll-to-roll process, the deformation amount of the glass film 11 and the deformation amount of the metal substrate 12 can be made comparable. The deformation of the glass film 11 can be prevented. Moreover, by setting the Young's modulus to 10 GPa or more, the difference between the distortion of the glass film 11 and the distortion of the metal substrate 12 that occurs when the glass film 11 and the metal substrate 12 are bonded can be reduced. It can suppress that stress is applied to the film 11 and can prevent the glass film 11 from cracking. In addition, as a measuring method of the Young's modulus of the metal base material 12, it is suitable to measure based on JISZ2280.

  Moreover, it is preferable that the thermal contraction rate of the metal base material 12 is 0.05% or less after baking after 230 degreeC and 150 minutes based on IPC TM650 Method2.2.4. Thereby, the difference between the thermal shrinkage rate (0.05% or less) of the glass film 11 and the thermal shrinkage rate of the metal substrate 12 can be reduced. Thus, by setting the heat shrinkage rate of the metal base 12 to 0.05% or less, for example, when forming the pixels 2, 3, and 4 for the color filter, the pixels 2, 3, and 4 are cured (post). Even if it is a case where it heat-processes and cools to make it bake), since the difference of the shrinkage amount of the glass film 11 and the shrinkage amount of the metal base material 12 is reduced, the glass film 11 is warped or the like. 11 can be prevented from being deformed, and the glass film laminate 10 can be stably conveyed in a roll-to-roll process.

  Next, the glass film laminated body 1a with a pixel for color filters is demonstrated using FIG. 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 for a color filter and a black matrix 5 are provided on the glass film 11 of the glass film laminate 10. 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 1a for a color filter, the color filter 1 shown in FIG. 1 is obtained by peeling the metal substrate 12 from the glass film 11 together with the adhesive layer 13.

  Next, the material of each component will be described.

  The material used for the glass film 11 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 11 is 5-300 micrometers. As a result, the glass film 11 can be stably manufactured, can have a minimum strength in handling, and the glass film laminate 10 having the glass film 11 can be wound into a roll. .

  Examples of the material used for the metal substrate 12 include stainless steel, copper, nickel, titanium, and iron. Among these, it is preferable to use stainless steel excellent in availability and corrosion resistance. Moreover, it is preferable that the thickness of the metal base material 12 is 1-200 micrometers. By setting the thickness of the metal substrate 12 to 1 μm or more, it is possible to secure the strength necessary for reinforcing the glass film 11 and to prevent the metal substrate 12 from being broken and improve the handleability. Moreover, by setting the thickness of the metal base 12 to 200 μm or less, it is possible to prevent the rigidity of the metal base 12 from becoming large and making it difficult to wind the glass film laminate 10.

  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, sufficient adhesive force can be secured for adhering the glass film 11 and the metal substrate 12.

  Next, the manufacturing apparatus (laminator) 20 of the glass film laminated body in this Embodiment is demonstrated using FIG.

  As shown in FIG. 4, the glass film laminate manufacturing apparatus 20 includes a glass film supply unit 21 to which a roll of the glass film 11 around which the belt-like continuous glass film 11 is wound, and a belt-like continuous metal substrate. And a metal base material supply unit 22 to which a roll of the metal base material 12 around which the metal 12 is wound is attached. Among these, a cover sheet (release paper) 14 is affixed to an adhesive layer 13 provided on one surface of the metal base 12 so as to be peeled off. The portions of the base material 12 are prevented from sticking together by the adhesive layer 13. Further, in the vicinity of the metal base material supply unit 22, the peeling unit 23 for peeling the cover sheet 14 from the metal base material 12 fed out from the metal base material supply unit 22 and the peeled cover sheet 14 are wound. A collecting unit 24 is provided for collecting and collecting.

  A pressing unit 25 for laminating the glass film 11 and the metal substrate 12 is provided on the downstream side in the transport direction of the glass film supply unit 21 and the metal substrate supply unit 22. By this pressing part 25, the metal base material 12 is laminated | stacked and affixed on the glass film 11 via the adhesion layer 13, and the glass film laminated body 10 shown in FIG. 2 is obtained.

  On the downstream side of the pressing portion 25, a winding portion 26 that winds the glass film laminate 10 around a cylindrical core 27a is provided. In this winding part 26, the glass film laminated body roll 27 by which the glass film laminated body 10 was wound up by the core 27a is formed.

  Next, the effect | action of this Embodiment which consists of such a structure, ie, the manufacturing method of the glass film laminated body by this Embodiment, is demonstrated using FIG.

  First, a strip-shaped continuous glass film 11 and a strip-shaped continuous metal substrate 12 with an adhesive layer 13 are prepared. That is, in the glass film laminate manufacturing apparatus 20, the roll of the glass film 11 is attached to the glass film supply unit 21, and the roll of the metal substrate 12 is attached to the metal substrate supply unit 22.

  Subsequently, the glass film 11 is fed out from the glass film supply unit 21, and the metal substrate 12 with the adhesive layer 13 is fed out from the metal substrate supply unit 22. At this time, the cover sheet 14 on the adhesive layer 13 drawn out from the metal base material supply unit 22 is peeled off from the adhesive layer 13 by the peeling unit 23, wound around the collection unit 24 and collected. In this way, the metal substrate 12 with the adhesive layer 13 from which the cover sheet 14 has been peeled is conveyed to the pressing portion 25.

  Next, in the pressing part 25, the metal substrate 12 is laminated and attached to the glass film 11 via the adhesive layer 13. Thus, the glass film laminated body 10 shown in FIG. 2 is obtained.

  Then, the obtained glass film laminated body 10 is conveyed by the winding-up part 26, and is wound up by the core 27a. Thus, the glass film laminated body roll 27 is formed.

  By the way, while manufacturing the glass film laminated body 10 in the manufacturing apparatus 20 of a glass film laminated body, the glass film 11 and metal currently conveyed by the winding part 26 from the glass film supply part 21 and the metal base material supply part 22 are shown. A predetermined tension is applied to the substrate 12. However, since the metal substrate 12 has a Young's modulus of 10 GPa or more, the deformation amount of the glass film 11 and the deformation amount of the metal substrate 12 can be made comparable, and the deformation of the glass film 11 can be reduced. Can be prevented.

  When manufacturing the color filter 1 using the glass film laminated body 10 mentioned above, first, the glass film laminated body 10 is drawn out from the glass film laminated body roll 27, and the photosensitive material for pixels is apply | coated on the glass film 11. FIG. Then, by repeating a series of steps of drying (pre-baking), exposure, development and post-baking for each pixel, the pixels 2, 3, 4 and black matrix 5 of each color are formed on the glass film 11.

  After development, the glass film laminate 10 on which the pixels are formed is wound up and put into a heating oven (not shown). In this heating oven, the glass film laminate 10 is heated at 200 ° C. for 30 minutes and post-baked, for example. The post-baked glass film laminate 10 is taken out from the heating oven and cooled in the atmosphere. By this cooling, the glass film 11 and the metal substrate 12 of the glass film laminate 10 contract. However, since the heat shrinkage rate of the metal base 12 is 0.05% or less, the shrinkage amount of the glass film 11 and the shrinkage amount of the metal base material 12 can be made comparable, and the glass film 11 is antireflective. It is possible to prevent the glass film 11 from being deformed by, for example.

  In addition, while applying a photosensitive material for pixels on the glass film 11 and performing drying, exposure and development, a predetermined tension is applied to the glass film 11 and the metal base 12. 12 has a Young's modulus of 10 GPa or more, so that the deformation of the glass film 11 can be prevented.

  Subsequently, a protective layer 6 covering each of the pixels 2, 3, and 4 is formed, and a transparent electrode film 7 is formed on the protective layer 6 to obtain a pixel-attached glass film laminate 1a for a color filter shown in FIG. It is done. Thereafter, the metal substrate 12 is peeled from the glass film 11 together with the adhesive layer 13 to obtain the color filter 1 shown in FIG.

  Thus, according to this Embodiment, the glass film 11 is supported by the metal base material 12. FIG. Thereby, the glass film 11 can be reinforced and the deformation of the glass film 11 can be prevented. In this case, the glass film laminated body 10 can be stably conveyed in a roll-to-roll process.

  Moreover, according to this Embodiment, when the metal base material 12 has a Young's modulus of 10 GPa or more, the difference between the Young's modulus of the glass film 11 and the Young's modulus of the metal base material 12 is reduced. Can do. In this case, even when tension is applied to the glass film laminate 10 in the roll-to-roll process, the deformation amount of the glass film 11 and the deformation amount of the metal substrate 12 can be made comparable. The deformation of the glass film 11 can be prevented.

  Moreover, according to this Embodiment, when the thermal contraction rate of the metal base material 12 is 0.05% or less, the difference between the thermal contraction rate of the glass film 11 and the thermal contraction rate of the metal base material 12 is calculated. Can be reduced. In this case, when forming the pixels 2, 3 and 4 for the color filter, the shrinkage amount of the glass film 11 can be obtained even when the pixels 2, 3 and 4 are heated and cooled to post-bake. The difference with the shrinkage | contraction amount of the metal base material 12 is reduced, and the deformation | transformation of the glass film 11 by the glass film 11 curving etc. can be prevented. As a result, the glass film laminate 10 can be stably conveyed in a roll-to-roll process.

  Moreover, according to this Embodiment, since the glass film 11 is supported by the metal base material 12, when the glass film laminated body with which the glass film 11 was supported by the plastic film (not shown) was heat-processed. Generation | occurrence | production of foreign materials, such as a deposited oligomer, can be prevented.

  Moreover, according to this Embodiment, since the glass film 11 is supported by the metal base material 12, the following advantages arise. That is, when a single glass film 11 is wound up with a foreign substance involved, the glass film 11 may be easily damaged by local impact, pressure, scratches, etc. By bonding the metal substrate 12, the glass film 11 is reinforced to prevent the glass film 11 from being damaged. Moreover, even if it is a case where the glass film 11 is cracked by bonding the metal base material 12 to the glass film 11, scattering of glass fragments and the like can be prevented.

  Furthermore, according to this Embodiment, the deformation | transformation of the glass film 11 of the glass film laminated body 10 in which the pixel 2, 3, 4 of multiple colors for color filters was provided can be prevented. Thereby, the accuracy of the display image of the color filter 1 can be improved.

  In the present embodiment, the example in which the metal substrate 12 is formed in a foil shape has been described. However, the present invention is not limited to this, and the metal substrate 12 may be formed in a net shape like a metal mesh, for example. Also in this case, the glass film 11 can be supported and the deformation of the glass film 11 can be prevented.

(Second Embodiment)
Next, the glass film laminated body in the 2nd Embodiment of this invention is demonstrated with FIG.

  The second embodiment shown in FIG. 5 is mainly different in that a supporting substrate having a glass cloth is laminated on a glass film via an adhesive layer, and the other configurations are shown in FIGS. This is substantially the same as the first embodiment shown in FIG. In FIG. 5, the same parts as those of the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, the glass film laminated body 10 in this Embodiment is equipped with the glass substrate 11 and the support base material 31 laminated | stacked through the adhesion layer 13 on the glass film 11. As shown in FIG. Among these, the support substrate 31 is constituted by a glass-containing plastic film 33 having a glass cloth 32.

  The glass cloth 32 is a woven fabric formed of a large number of fine glass fibers. It does not specifically limit as a material used for this glass fiber, It can be set as the material similar to the glass film 11. FIG. Moreover, it is preferable that the fiber diameter of glass fiber is 3-24 micrometers. This makes it possible to secure the strength necessary for reinforcing the glass film 11 and wind the glass film laminate 10 having the glass cloth 32 into a roll. In addition, as a measuring method of the fiber diameter of glass fiber, it is suitable to measure based on JISL1095.

  The glass-containing plastic film 33 is obtained by impregnating a glass cloth 32 with a resin, and the plastic material used here is not particularly limited. For example, acrylic resin, epoxy resin, polyamide resin, phenol Examples thereof include synthetic resins such as resins. Moreover, it is preferable that the thickness of the glass containing plastic film 33 is 10-300 micrometers. This makes it possible to ensure the strength necessary for reinforcing the glass film 11 and to wind the glass film laminate 10 having the glass-containing plastic film 33 in a roll shape.

  In addition, the glass film laminated body 10 which has the support base material 31 in such this Embodiment uses the manufacturing apparatus 20 of the glass film laminated body shown in FIG. 4, and the glass film laminated body by 1st Embodiment. 10 can be produced in the same manner.

  Thus, according to this Embodiment, the glass film 11 is supported by the glass containing plastic film 33 which has the glass cloth 32 as the support base material 31. FIG. Thereby, the glass film 11 can be reinforced and the deformation of the glass film 11 can be prevented. In this case, the glass film laminated body 10 can be stably conveyed in a roll-to-roll process.

  In particular, according to the present embodiment, since the support base material 31 has the glass cloth 32, the difference between the Young's modulus of the glass film 11 and the Young's modulus of the support base material 31 can be reduced. In this case, in the roll-to-roll process, the deformation amount of the glass film 11 and the deformation amount of the support base material 31 can be made comparable, and the deformation of the glass film 11 can be prevented. In addition, since the difference between the thermal shrinkage rate of the glass film 11 and the thermal shrinkage rate of the support base material 31 can be reduced, the shrinkage amount of the glass film 11 and the support base even when it is cooled by heat treatment. The difference from the shrinkage amount of the material 31 is reduced, and deformation of the glass film 11 due to warpage of the glass film 11 can be prevented. As a result, the glass film laminate 10 can be stably conveyed in a roll-to-roll process.

  Moreover, according to this Embodiment, since the glass film 11 is supported by the glass containing plastic film 33, the glass film 11 can be reinforced. For this reason, even when the glass film laminated body 10 is wound up with a foreign substance involved, it is possible to prevent the glass film 11 from being damaged by local impact, pressurization, scratches, or the like. Moreover, even if it is a case where the glass film 11 is cracked by bonding the glass containing plastic film 33 to the glass film 11, scattering of glass fragments etc. can be prevented.

  Furthermore, according to this Embodiment, the deformation | transformation of the glass film 11 of the glass film laminated body 10 in which the pixel 2, 3, 4 of multiple colors for color filters was provided can be prevented. Thereby, the accuracy of the display image of the color filter 1 can be improved.

  In the present embodiment, the example in which the support base 31 is constituted by the glass-containing plastic film 33 having the glass cloth 32 has been described. However, the present invention is not limited to this, and as shown in FIG. 6, the support base material 31 may be composed of only the glass cloth 32. Also in this case, the glass film 11 can be reinforced and the deformation of the glass film 11 can be prevented. Further, in this case, since the support base material 31 does not contain a plastic material, an oligomer or the like that is deposited when the glass film 11 is heat-treated by the glass film 11 supported by the plastic film (not shown). Generation of foreign matter can be prevented. In addition, it is preferable that the thickness of the glass cloth 32 used in the form shown in FIG. 6 is 10-300 micrometers. This makes it possible to secure the strength necessary for reinforcing the glass film 11 and to wind the glass film laminate 10 having the glass cloth 32 into a roll. As such a glass cloth 32, for example, a glass cloth E06B (thickness 55 μm) manufactured by Unitika Ltd. can be used. In addition, as a measuring method of the thickness of the glass cloth 32, it is suitable to measure using the Olympus ultrasonic thickness measuring apparatus (35DL-HP).

A cover sheet 14 is affixed to the adhesive layer 13 provided on the metal substrate 12 so as to be peelable.

  Then, the glass substrate 11 was obtained by laminating and pasting the metal substrate 12 on the glass film 11 via the adhesive layer 13 with a laminator. The obtained glass film laminate 10 was wound around a core 27 a having a diameter of 6 inches to form a glass film laminate roll 27.

  Next, the glass film laminated body roll 27 was set to the unwinding part of the coating apparatus, and the glass film laminated body 10 was drawn out.

  And the resist was apply | coated by the micro gravure on the glass film 11 of the drawn-out glass film laminated body 10, and exposure and image development were performed after that.

  After the development, the glass film laminate 10 was wound up, put into a heating oven, and post-baked by heating at 200 ° C. for 30 minutes. After the post-baking, the glass film laminate 10 was taken out from the heating oven and cooled in the atmosphere.

  Then, it set to the unwinding part of the coating device for other pixels, and the glass film laminated body 10 was drawn | fed out. At this time, it was confirmed that the glass film laminate 10 was smoothly drawn out. That is, it was confirmed that the glass film 11 was not deformed such as warpage.

(Comparative example)
Glass in the same manner as in the examples except that a PET film with an adhesive layer (Lintec Co., Ltd., Fuji Clear 50) having a thickness of 50 μm, a width of 300 mm, and a length of 10 m was used as a supporting substrate instead of the metal substrate 12. A film laminate was prepared. However, after post-baking and cooling as in the examples, the glass film laminate was set out on the unwinding portion of the coating apparatus and was fed out.
