Description

  The present invention relates to a method of manufacturing a microprojection on a substrate, and relates to a method of manufacturing a microprojection having a height controlled by patterning, and more particularly to a method of manufacturing a spacer resin column of a liquid crystal display device.

  A panel member used for a liquid crystal color television or the like has a liquid crystal layer in a minute space (cell) formed by bonding a color filter substrate provided with a transparent electrode and a transparent substrate provided with a pixel electrode such as a TFT. Is sealed. The spacer for a liquid crystal display device is used for defining and controlling the thickness of the cell. Since the thickness of the cell is the thickness of the liquid crystal layer as it is, there is only a difference of about 0.1 μm in the thickness of the cell in a part of the panel. A decrease in contrast occurs.

  Conventionally, as a method for manufacturing a spacer for a liquid crystal display device, a method of randomly dispersing glass or resin spacer beads on a substrate provided with pixel electrodes has been used. However, in the spraying method, beads are also arranged on the pixel pattern, so liquid crystal alignment failure and light leakage around the beads have been problems.

  In order to solve this, Patent Document 1 proposes a method in which spacer beads are arranged on a black matrix, which is a light-shielding portion in a color filter, by an inkjet method. However, since it is difficult to make ink droplets small and the accuracy of landing is about 20 μm, the ink jet method can be sufficiently arranged in a pixel space of about several tens to several hundreds of μm in a color filter. However, it cannot be adopted as a method for forming the black matrix of a color filter having a line width of about 10 μm with high definition and precision.

  In recent years, as a method for forming a spacer on a black matrix, for example, Patent Document 2 discloses a method of forming a columnar spacer by a photolithography method. According to this method, the patterning accuracy is higher than that of the above method, and thus it can be arranged on the black matrix. However, there is a step of applying a photosensitive resin layer on the substrate and performing pattern exposure / development processing. Therefore, there is a problem that the manufacturing equipment becomes large and the manufacturing cost is high, and particularly in the case of a large panel, it is difficult to make the resin pillars uniform in height.

The above background art documents are shown below.

  The predetermined position on the substrate to be printed is, for example, immediately above the black matrix in the color filter when the microprojection of the present invention is used as a spacer resin column for a liquid crystal display device. The ink-removable glass substrate means a substrate made of a material that can easily peel the curable resin ink film. The curable resin is a resin that can be cured by light or heat.

  According to the first aspect of the present invention, by transferring the pattern formed on the ink-peelable glass substrate, the pattern can be formed without damaging the substrate to be printed in the manufacturing process.

  An embodiment of a method for producing a microprojection of the present invention will be described in detail below based on the drawings (FIG. 2) and (FIG. 3).

  FIG. 2 is a diagram for explaining an example of a process of forming a microprojection pattern 204 made of a curable resin ink film on the ink peelable glass substrate 201 according to the present invention.

  The ink releasable glass substrate 201 may be any one having releasability with respect to the curable resin ink film described later.

  In order to impart ink releasability to the glass substrate, a release agent represented by silicone oil or silicone varnish may be applied, or a thin film layer of silicone rubber may be formed. In order to obtain the same effect, a fluorine resin or a fluorine rubber can also be used. Alternatively, the fluororesin fine powder may be mixed with silicone rubber or ordinary rubber to impart peelability. Although these silicone-based coatings usually have low adhesion to the glass substrate, they are more adhesive to the glass substrate than the thermosetting or UV-curable acrylic resin, epoxy resin, or silicone layer provided on the outermost surface. A high resin layer or a silane coupling agent may be provided on the glass substrate in advance as an anchor layer, and may be provided on the upper layer.

  Specific silicones include dimethylpolysiloxanes with various molecular weights, other methylhydropolysiloxanes, methylphenylsilicone oils, methylchlorinated phenylsilicone oils, or copolymers of these polysiloxanes with organic compounds. Can be used.

  Silicone rubber is a combination of two-component diorganopolysiloxane and a tri- or higher functional silane as a crosslinking agent, or a combination of siloxane and a curing catalyst, or one-component diorganopolysiloxane, acetone oxime, and various methoxys. Combinations of silane, methyltriacetoxysilane, etc., and other polysiloxanes for adjusting rubber hardness can be used.

Moreover, a silane coupling agent can also be used as another processing method which provides the ink peelability of the glass substrate surface. As the silane coupling agent, trimethoxysilanes and triethoxysilanes that can react with glass can be used. One part of the silane coupling agent can be selected from those having a reactive group with an organic compound such as a vinyl group, an epoxy group, an amino group, a methacryl group, a mercapto group, or an alkyl group or a part thereof. Those having a fluorine atom substituted or those having a substituent bonded to form a surface with a small surface energy by bonding with siloxane can be used. When the former silane coupling agent having a reactive group is used, after the glass surface is treated with the silane coupling agent, other monomer components that give a predetermined surface free energy are applied and bonded. be able to. Examples of the silane coupling agent having a reactive group include vinyl methoxy silane, vinyl ethoxy silane, p-styryl trimethoxy silane, 3-glycidoxy propyl trimethoxy silane, 2- (3,4 epoxy cyclohexyl) ethyl trimethoxy silane. , 3-methacryloxypropylmethyldiethoxysilane, 3-acryloxypropyltrimethoxysilane, etc., and styrene, ethylene glycol diglycidyl ether, trimethylpropane triglycidyl ether, lauryl acrylate, dipentaerythritol hexa Acrylate or the like can be used. As the silane coupling agent having no reactive group, methyltrimethoxysilane, n-hexyltrimethoxysilane, n-octyltrimethoxysilane, dodecyltrimethoxysilane and the like can be used. However, it is not limited to an alkyl group.

  First, as shown to (a) of FIG. 2, curable resin ink is apply | coated on the ink peelable glass substrate 201. FIG.

  As a method for forming the curable resin ink film 202 on the ink peelable glass substrate 201, a known coating method can be used depending on the viscosity of the ink and the drying property of the solvent. That is, spin coating, dipping method, roll coating, gravure coating, reverse coating, air knife coating, comma coating, die coating, screen printing method, spray coating, gravure offset method and the like can be mentioned. Among them, the die coat, gap coat, roll coat, and applicator can form a uniform ink film for inks with a wide range of viscosity, and continuously form them on a movable ink-peelable glass plate. In some cases, die coating is the most efficient and preferred coating method.

  After the curable resin ink is applied onto the ink peelable glass substrate 201 by the above method, it is preliminarily dried. For this preliminary drying, natural drying, cold air / hot air drying, microwave, vacuum drying, or the like can be used. Alternatively, radiation such as ultraviolet rays and electron beams can be used. This preliminary drying is intended to increase the viscosity or thixotropy of the curable resin ink, and does not completely cure the curable resin ink. Therefore, it is preferable to adjust a dry state with the composition of the curable resin ink to be used. It is important that the film thickness of the curable resin ink film 202 in the pre-dried state formed at this time is equal to or slightly larger than the particle diameter of the spacer described later. As a result, the height of the fine protrusions can be made uniform when transferred to the substrate to be printed.

  As the curable resin ink used in the present invention, a known photocurable resin or thermosetting resin can be used. For example, an epoxy resin, a polystyrene resin, a melamine resin, a phenol resin, an acrylic resin, an unsaturated polyester resin, a polyurethane resin, and the like can be used, and a curing agent and a crosslinking agent may be mixed as necessary. Moreover, when aligning, it can color as needed.

Further, the curable resin can be used by dissolving in a solvent as necessary. For example, methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, methoxy alcohol, ethoxy alcohol, methoxy ethoxy ethanol, ethoxy ethoxy ethanol, ethyl acetate, butyl acetate, methyl methoxypropionate, ethyl ethoxypropionate, ethyl lactate, acetone , Methyl isobutyl ketone, cyclohexanone, methoxyethyl acetate, ethoxyethyl acetate, ethyl cellosolve acetate, methoxyethoxyethyl acetate, ethoxyethoxyethyl acetate, diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, propylene glycol monomethyl ether acetate, tetrahydrofuran, N, N -Dimethylformua De, N, N- dimethylacetamide, N- methylpyrrolidone, .gamma.
Examples include butyrolactone, benzene, toluene, xylene, n-hexane, n-heptane, and n-octane.

  Next, as shown in FIGS. 2B and 2C, unnecessary portions are removed using a removal plate 203 having a negative pattern with respect to the fine protrusion pattern, and the fine protrusion of the curable resin ink film is removed. An object pattern 204 is formed. As the removal plate 203, a known resin relief plate can be used. For example, a plate made of nylon, acrylic, silicone resin, styrene-diene copolymer, or a rubber plate such as ethylene-propylene, butyl, or urethane rubber can be used. Such resin-made relief plates have already been used for relief printing and flexographic printing, and can be produced by pouring a predetermined resin into a previously produced mold or by engraving. A method using a conductive resin is preferable because a highly accurate one can be produced. A plate depth of about 2 μm to 30 μm can be used.

  Next, based on FIG. 3, the process of transferring the fine projection pattern 204 of the formed curable resin ink film according to the present invention onto the substrate to be printed will be described.

  As the substrate to be printed used in the present invention, since the spacer resin pillar is not directly formed, there is little damage to the base material, and it can be processed into not only glass but also plastic.

  Specifically, a film or sheet of polyethylene terephthalate, polyethylene naphthalate, polyether sulfone, cycloolefin polymer, polyimide, nylon, aramid, polycarbonate, polymethyl methacrylate, polyvinyl chloride, triacetyl cellulose, or the like is used as the plastic substrate. be able to. Furthermore, it is preferable to use a light-transmitting substrate because alignment can be facilitated when patterns to be described later are superimposed.

  In the present invention, as shown in FIG. 3 (d), in order to define the height of the microprojection to be manufactured, the microprojection pattern 204 made of a curable resin ink film on the ink peelable glass substrate is removed. A spacer 301 is disposed in the opening. By this process, a projection having a uniform height is formed, and further, the spacer 301 is disposed in the vicinity of the smile projection, and the shape of the projection is deformed unevenly due to the printing pressure during transfer. Is more effective.

  A known inkjet device and inkjet head can be used for the spacer arrangement. By ejecting the spacer dispersed in the dispersion medium from the ink jet nozzle 302, the spacer is selectively disposed in the vicinity of a predetermined position where the minute protrusions are formed on the substrate to be printed. The nozzle diameter of the ink jet head is not limited in consideration of ink droplet ejection properties and prevention of nozzle clogging by the spacer, but it is preferably 5 or more times the diameter of the spacer.

  As the spacer 301 used in the present invention, known spacer beads can be used as a spacer for a liquid crystal display device. For example, glass for inorganic components, acrylic resin, epoxy resin, phenol resin, melamine resin, unsaturated polyester resin, divinylbenzene copolymer, divinylbenzene-acrylic ester copolymer, diacrylphthalate as organic components Copolymers, allyl isocyanurate copolymers and the like can be used. In addition, the particle size of the spacer defines the height of the microprojections. Since the ink film undergoes volume shrinkage during ink film pre-drying and curing, the ink volume shrinkage is calculated in advance and pre-dried. It is preferable to use beads that are the same as or slightly smaller than the film thickness and slightly larger than the height of the target space resin column. Naturally, the degree of volume shrinkage varies depending on the concentration of the curable resin in the ink, the type of the dispersion medium, and the mixing ratio.

  When arranging the spacers by the ink jet method, it is conceivable to disperse them in a suitable dispersion medium. Specific examples of the dispersion medium include water, ethylene glycol, isopropyl alcohol, etc. The volatility and viscosity can be adjusted. The concentration of the spacer in the dispersion medium needs to be set in a range in which the spacers do not aggregate or overlap when discharged onto the ink peelable glass substrate.

  Next, as shown in FIG. 3E, the transparent electrode 304 of the substrate to be printed is brought into contact with the ink-peelable glass substrate 306 on which the fine protrusion pattern 307 of the curable resin ink film is formed, and the pattern is transferred. .

  In the case where a microprojection is used as a spacer for a liquid crystal display device, it is desirable that the microprojection pattern be matched on the black matrix. For alignment, an ink peelable glass substrate provided with a microprojection pattern is fixed on a movable stage, and the printed substrate is brought close to about 100 to 250 μm from above, and then obtained on the ink peelable glass substrate. A part of the pattern and the mark pattern for alignment and the mark pattern on the substrate to be printed are recognized in the transmission image, and the movable stage is operated based on the image on which the pattern on the respective substrate is recognized to determine the transfer position. Correction can be performed. In addition, a method can be selected in which a microscope camera is inserted between the ink-peelable glass substrate and the substrate to be printed, and the position is corrected based on images obtained by recognizing patterns on the respective substrates. The microscope camera may be either an optical microscope or a CCD (Charge Coupled Device) microscope, but requires either autofocus, an electrically controllable manual focus control mechanism, or both. For this purpose, it is possible to have an interface to an external monitor or an image processing apparatus for position correction.

  After alignment, the substrate to be printed and the ink-removable glass substrate are brought into contact with each other by using a roller, a squeegee, air blowing, vacuum lamination, etc., and transferred with uniform printing pressure. At this time, the presence of the spacer between the substrate to be printed and the ink-removable glass substrate allows the height to be defined by the particle size of the spacer, thus making it possible to evenly align the height of the microprojections. .

  As shown in FIG. 3 (f), after transferring from the ink peelable glass substrate to the substrate to be printed, the curable resin ink film in a pre-dried state is cured. In the curing step, a known curable resin curing method such as heating or light irradiation can be used according to the properties of the curable resin ink film.

After the fine protrusions are fixed on the substrate to be printed in the above process, the spacer transferred onto the substrate to be printed without being absorbed and removed by the ink-removable glass substrate is removed as shown in FIG. To do. The spacer can be removed by spraying a liquid such as air, water, or a mixed fluid thereof. The fluid spraying pressure at the time of removing the spacer is sufficient if it has sufficient pressure to remove the spacer, and may be a strength that does not affect the formed microprojections and the substrate to be printed. Although a pressure is not limited, It is desirable that it is 0.2-1.0MPa / cm < ² >.

  Through the above steps, microprojections are formed. In the present invention, since the substrate is not directly formed on the substrate to be printed, the substrate to be printed is not damaged in the manufacturing process. It is possible to form. Moreover, since the height of the microprojections can be defined by the particle size of the spacer, the height can be made uniform.

  Specific examples of the present invention will be described below.
