Description

[Technical Field] The present invention relates to a color filter for a liquid crystal display or the like, and particularly relates to a filter method for forming a color pixel layer by an inkjet printing method. [Prior Art] 0 A color filter is used for assembly in a liquid crystal display device to be colored, or used for assembly in a solid-state image pickup device to obtain a color optical element. Such color filters are known to have a coloring pattern comprising complex layers formed adjacent to each other on the same plane on the substrate. Here, in the coloring pattern, a black matrix as a light shielding layer is formed between the color pixel layers of the color element layers of the three primary colors of the red color pixel layer, the 'pixel layer, and the blue color pixel layer. Each of the layers is a transparent layer of colored colors, and a black matrix (Black 〇 is black, which is substantially a light-shielding partition that does not transmit visible light. As a general method of manufacturing a color filter, a method of fabricating a photolithography method is known. A coloring photosensitive resin composition layer containing a coloring photosensitive resin component is formed on the substrate, and the colored photosensitive material contains a coloring agent of each color, and the coloring photosensitive resin group is irradiated with light through a mask. A color pattern is formed on the substrate with respect to the change in developability (for example, 曰07-27 1 020). However, in the method of manufacturing a color filter of the photolithography method, the manufacturing method of the color method is shown. The color pattern of the color image is colored by a number of colors, and the color of the green color is adjacent to the color of the matrix. The liquid of the solid resin composition layer of the finished product is dissolved in the color of the liquid to be colored -5 - 201044031 After the photosensitive resin composition is applied to the surface of the substrate, it is necessary to repeat the step of exposing the mask to remove unnecessary portions, and the manufacturing steps are complicated. Depreciation of equipment costs such as expensive masks, coating equipment, exposure equipment, and equipment are required. Therefore, in order to simplify the manufacturing steps and reduce the cost, a color element layer based on an inkjet printing method has been proposed instead of the photolithography method. In the inkjet printing method, a black matrix having a light-shielding property is generally used as a wall, and an ink coloring pixel layer for inkjet printing is printed on an opening of the black matrix. However, when printing is performed, the component concentration of the ink for inkjet printing is used. There is a limitation. Therefore, in order to obtain a desired thickness and color, it is necessary to print an ink for inkjet printing having a volume several times or more with respect to the volume of the opening of the black matrix (opening area X partition). The ink for inkjet printing which has been printed overflows from the opening, and the ink is mixed in the inkjet printing ink which enters the other color in the adjacent opening as the color matrix of the partition. For the problem of the "mixing color", for example, it is proposed that the liquid repellency of the ink for inkjet printing is increased by performing plasma treatment in the atmosphere of a fluorine compound such as tetraoxane. For example, International Publication No. WO99/483 No. 39) is added with an organic deuterated or organic fluorine compound to form a partition wall to which liquid repellency with respect to ink for inkjet printing is imparted (for example, Japanese Patent Laid-Open No. 07-3 5 9 1 No. 5, Japanese Patent Laid-Open No. 2006- 1 6323 No. 3). In the method disclosed in International Publication No. WO99M8 3 3 9 , since the surface of the partition wall is fluorinated by the ion-exchange treatment, the surface of the partition wall is formed to be separated from the passing and developing to form a black solid. Surface method (Inorganic inkjet inkjet -6-201044031 The lyophobic property of the printing ink becomes uniform, but becomes a plasma processing step, and cannot be said to be a simplified method. Further, Japanese Patent Laid-Open No. 07 In the method disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2006-1 63 23 No., the partition wall is formed using a composition containing an organic ruthenium compound or an organic fluorine compound, so that it can be formed for inkjet printing. The liquid repellency partition wall of the ink can prevent color mixture due to the incorporation of the color ink in the adjacent color pixel layer, but is insufficient in ensuring uniform liquid repellency on the entire surface of the partition wall. In the case where the liquidity is uneven, when the ink for inkjet printing is printed on the pixel region surrounded by the partition wall, that is, the opening portion of the black matrix, localized The problem of defective charging is a problem of pixel defects such as "leakage". In the color filter produced in the state where local leakage occurs, the light leakage in the white portion is a problem. In the case of producing a color filter by the inkjet printing method, the flatness of the color pixel layer becomes a problem. The reason is that a large amount of oil ink is required to be filled into the opening portion to achieve a prescribed color density, and the ink is in the drying step. The large volume reduction is a large amount of pigments or resins, which is a cause of difficulty in leveling. In addition, 'the method of flattening the color layer using a flat film such as a transparent protective film is also considered. Since a coating apparatus or a flattening film material for coating a planarizing film is used in a large amount, it is impossible to achieve the object of the inkjet printing method, that is, the simplification of the manufacturing steps and the reduction of the manufacturing cost. [The present invention] Providing a method for manufacturing a color filter, which is excellent in flatness of the color layer 201044031, and prevents color mixture caused by the incorporation of the different color ink layers between the adjacent color pixel layers It is possible to prevent a pixel defect such as localized whitening. The present invention is a method of manufacturing a color filter, which is a color filter having a plurality of color pixel layers on a substrate and a light-blocking partition wall between adjacent color pixel layers. The manufacturing method includes the step of forming a first color pixel layer in which the non-crosslinkable colored ink is filled in the opening partitioned by the light shielding partition walls; and the solid content concentration is 30% by weight or more, and yields 値O.OlmPa In the crosslinkable ink, the crosslinkable ink is formed in the opening of the first color element layer in a state where the contact angle of the crosslinkable ink with respect to the light-shielding partition is 25 degrees or less. a step of hardening; and a hardening step of curing the charged crosslinkable ink. According to the invention, in the step of forming the first color pixel layer, the non-crosslinkable colored ink is filled to the light-shielding partition In the opening portion, the first color element layer is formed, and in the crosslinkable ink filling step, the crosslinkable ink is in a state in which the contact angle with respect to the light-shielding partition wall of the crosslinkable ink is 25 degrees or less. Lower to full charge The opening of the first color pixel layer. In this case, the crosslinkable ink has a solid content concentration of 30% by weight or more and a yield enthalpy of 0.011 mPa or less. By setting the charging conditions in the crosslinkable ink charging step as described above, it is possible to prevent the color mixture of the adjacent color pixel layers from being mixed by the mixed color inks while having excellent flatness of the color pixel layer. It can prevent pixel defects such as local leakage. -8- 201044031 The present invention further includes 'adopting the surface of the aforementioned light-shielding partition wall with ultraviolet rays before adjusting the cross-linking ink, and adjusting the contact angle of the cross-linking ink with respect to the light-shielding partition wall . Further, according to the present invention, the surface of the light-shielding partition wall is irradiated with ultraviolet rays before the cross-linking ink is filled, and the contact angle of the cross-linkable ink with respect to the light-shielding partition wall is adjusted. Thus, the contact 0 angle can be easily adjusted to the desired enthalpy without changing the composition of the crosslinkable ink. The present invention also includes that the 'shading partition wall is a black matrix, and the black matrix is obtained by patterning a photosensitive black resin composition layer on a substrate. The present invention further includes 'the first color pixel layer forming step by charging A non-crosslinkable colored ink containing a solvent and dried. The present invention also includes a contact angle of 5 degrees or less with respect to the non-crosslinkable colored ink at the bottom of the opening of the light-shielding partition. 〇 The present invention also includes that the wavelength of the ultraviolet ray to be irradiated is 300 00 nm or less. The present invention also includes an ultraviolet irradiation amount of 500 mJ/cm2 or less. The present invention also includes that the hardening of the crosslinkable ink is carried out by ultraviolet irradiation or heating. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The present invention is a method of manufacturing a color filter having a plurality of color pixel layers on a substrate and a light-blocking partition wall between adjacent color pixel layers, including: -9 - 201044031 First color pixel layer forming step in which the non-crosslinkable coloring ink is filled in the opening portion between the light shielding partition walls; the solid content concentration is 30% by weight or more, and the yield is less than 0.01 mP a In the state in which the contact angle of the crosslinkable ink with respect to the light-shielding partition wall is 25 degrees or less, the cross-linking ink is filled in the cross-linking ink filling step in which the opening of the first color element layer is formed. And a hardening step of hardening the aforementioned crosslinkable ink. In the following, the present invention will be described by way of a method in which a black matrix is used as a light-blocking partition. However, in the case where, for example, a metal thin film pattern is used as a black matrix, a resin partition pattern may be separately formed. The photosensitive black resin composition for producing the light-shielding partition may be of a negative type or a positive type, and is preferably a negative type which can set a higher optical density. The color filter can be obtained by forming a black matrix substrate obtained by using a photosensitive black resin composition on a substrate to form a black matrix, and forming a color element layer in the opening of the black matrix. (Production of Black Matrix Substrate) The black matrix substrate can be obtained by patterning a photosensitive black resin composition layer on a substrate. The black matrix substrate can be manufactured by, for example, the steps described below. 1A to 1C are views showing the steps of a manufacturing step of a black matrix substrate. The manufacture of the black matrix substrate 7 begins with the preparation of the substrate 2, which is a substrate on which a black matrix is formed. Examples of the substrate 2 include, in addition to a glass substrate and a tantalum substrate, a polycarbonate substrate, a polyester substrate, an aromatic polyamide substrate, a polyimide substrate, a polyimide substrate, and a poly ring. A resin substrate such as an olefin substrate, an epoxy substrate-10-201044031, an acrylic substrate, various copolymer substrates, or a composite substrate. Further, the substrate 2 may be subjected to a pretreatment such as a drug treatment using a drug such as a decane coupling agent, a plasma treatment, an ion plating treatment, a sputtering treatment, a gas phase reaction treatment, or a vacuum vapor deposition treatment. Then, a photosensitive black resin composition is applied on one surface in the thickness direction of the substrate 2. As the coating method, for example, a spin coating method (spin coating method), a cast coating method, a roll coating method, a slit coating method, a slit and spin coating method, or a non- A known coating method such as a spin coating method. After the photosensitive black resin composition is applied onto the surface of the substrate 2, the solvent is volatilized by drying, and as shown in Fig. 1A, a photosensitive black resin composition layer 1 having a predetermined film thickness is formed on the substrate 2. Then, as shown in FIG. 1B, the photosensitive black resin 'component layer 1 is irradiated with the light 4 via the mask 3. Here, in Fig. 1B, the photosensitive black resin composition layer 1 will be described as a material formed using a negative photosensitive resin composition. The Q mask 3 is, for example, a material obtained by providing a light shielding layer 3 2 on the surface of the glass plate 31 or the like. The light 4 is shielded by the light shielding layer 32. The portion of the glass plate 3 1 where the light shielding layer 32 is not provided is the light transmitting portion 33, and the light 4 is transmitted through the light transmitting portion 3 to the photosensitive black resin composition layer 1, and the photosensitive black resin composition layer 1 is irradiated. The pattern of the light transmitting portion 33 is transferred and exposed. Further, in order to increase the exposure sensitivity, an oxygen blocking film such as PVA may be applied onto the surface of the photosensitive black resin composition layer 1. As the light ray 4, ultraviolet rays such as a g line (wavelength 4 3 6 nm) and an i line (wavelength 365 nm) are usually used. Preferably, the light ray 4 is irradiated as parallel light onto the black tree -11 - 201044031 on the fat composition layer 1, and is usually irradiated through a mask alignment machine (Mask Aligner, not shown) or the like. The exposure of the photosensitive black resin composition layer 1 can be carried out via the mask 3 using a known projection exposure apparatus or a proximity exposure apparatus, or can be carried out using a maskless drawing device using laser as a light source. The irradiation amount of the light 4 is based on the content of the light-shielding agent in the photosensitive black resin composition, the kind or content of the binder resin, the kind or content of the compound having an ethylenic unsaturated bond and capable of addition polymerization, and the photopolymerization initiator. The type or content, and further, the wavelength of the light source used in the exposure apparatus, the extraction wavelength, and the power are appropriately selected. When the exposure of the photosensitive black resin composition layer 1 is completed, development is carried out. The photosensitive black resin composition layer 1 after exposure may be brought into contact with the developing solution during development. As the developer, for example, an alkaline aqueous solution can be used. As the alkaline aqueous solution, for example, sodium hydroxide, potassium hydroxide, sodium carbonate, sodium citrate, sodium metasilicate, aqueous ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide can be used. An aqueous solution of a water-soluble basic compound such as ammonium, tetraethylammonium hydroxide, choline, pyrrole, acridine or 1,8-diazabicyclo-[5,4,0]-7-undecene; The concentration is 0.001 to 10% by mass, preferably 〇.〇1 to 1 by mass, based on the mass fraction. /. degree. The aqueous alkali solution may contain a water-soluble organic solvent such as methanol or ethanol, or a surfactant. An organic solvent may be used as the developing solution. For example, a solvent contained in the photosensitive black resin composition may be suitably used in combination. The developing method is not particularly limited, and can be developed by, for example, a immersion developing method (immersion developing method), a shower developing method, a spray developing method, or a paddle type (paddle -12-201044031) developing method (full liquid developing method). The development temperature is usually in the range of 10 to 40 ° C, and the development time is usually i 〇 to 300 °. The light-unirradiated area of the photosensitive black resin composition layer 1 which is not irradiated with the light 4 is dissolved and removed in the developing solution by development. On the other hand, the light irradiation region of the photosensitive black resin composition layer 1 irradiated with the light 4 remains on the substrate 2'. As shown in Fig. 1C, a black matrix (partition pattern) 5BM can be formed on the surface of the substrate 2 which can be manufactured. Black matrix substrate 7. In the case where the photosensitive black resin composition layer 1 is dissolved and removed by the development treatment, the opening portion of the black matrix 5BM is formed. In the black matrix substrate 7, the height of the partition wall of the black matrix 5BM (the film thickness of the color matrix 5BM) A is ί.ίμηι 1010 μm, preferably 〇.2ym~5.0# m, particularly preferably 0.2//m~3.0" m. When the height A of the partition of the black matrix 5BM is smaller than that, it is difficult to charge a sufficient amount of ink for inkjet printing to the opening of the black matrix 5 B 以 to achieve the color density required for color reproduction. When the height 隔 of the partition wall exceeds 10; / m, it is difficult to produce a black matrix substrate 7 having a high-Q precision partition pattern, and when the color filter is manufactured using the black matrix substrate 7, the color pixel layer and the partition wall are formed. The gradient difference (step difference) becomes large, and thus the design of the unit cell becomes difficult. Further, the width B of the partition wall in the black matrix 5BM of the black matrix substrate 7 is usually set to be about 50/zm or less, preferably about 10 to 2 〇Αίηη. Further, the opening of the black matrix 5A as the region surrounded by the partition walls is generally rectangular. From the viewpoint of the ink filling property, the corner portion may have an R shape having a radius of about #m. The opening of the black matrix 5ΒΜ is a square shape. The length C of one side of the opening is usually set to about 20 to 150/zm -13 to 201044031. Further, in the case where the opening of the black matrix 5 B 为 is rectangular, the size of the opening portion is usually set to be (20 to 150) vmx (70 to 500). In the case where an alkaline aqueous solution is used as the developing solution, the black matrix substrate 7 produced by the development treatment is subjected to water washing and heat treatment after the development treatment. The heat treatment was carried out at 150 to 250 ° C for 5 to 30 minutes to exhibit sufficient stability. That is, the black matrix 5 B 不 did not cause so-called dissolution or swelling deformation with respect to the ink for inkjet printing. • Photosensitive Black Resin Composition As described above, in the production of the black matrix substrate, a black matrix as a light-shielding partition wall is formed on the substrate by using the photosensitive black resin composition. In the case where the photosensitive black resin composition is a negative type, the photosensitive black resin composition may contain an opacifier (A), a binder resin (B), a compound (C) having an ethylenically unsaturated bond and capable of addition polymerization, and Photopolymerization initiator (D), photopolymerization initiation aid (E), surfactant (F), solvent, and the like. Further, when the photosensitive black resin composition is a positive type, the photosensitive black resin composition may contain an opacifier (A), a binder resin (B), a photosensitizer (G), or the like. Further, a crosslinking agent may be further contained as needed. The opacifier (A) may be a dye or an organic pigment or an inorganic pigment. Further, it is also possible to use the dye and the pigment in a mixed state. Examples of the inorganic pigment include metal compounds such as metal oxides and metal complexes, and specific examples thereof include iron, cobalt, aluminum, cadmium, lead, and -14 - 201044031 copper, titanium, magnesium, chromium, and zinc. An oxide or a metal oxide, a nitride, or an oxynitride of a metal such as ruthenium. Further, as the organic pigment, specifically, a compound classified as a pigment in a color index (c 〇1 〇 u Γ 1 n d e x (T h e S 〇 c i e t y 〇 f D y e r s a n d Colourists)) may be mentioned. In particular, when a black matrix is formed, a photosensitive resin composition containing a black pigment can be used as the colorant (A). The binder resin (B) is a component in which a resin composition layer formed using the photosensitive black resin composition is imparted with a property in which a light-irradiated region is dissolved in a developer in a negative photosensitive black resin composition. Further, the binder resin also functions as a dispersion medium for dispersing the light-shielding agent in the resin composition layer formed using the photosensitive black resin composition. The binder resin (B) used in the negative photosensitive black resin composition may be an acrylic copolymer or a reaction product of an epoxy compound having two or more epoxy groups in the molecule and a carboxylic acid. A polycarboxylic acid resin or the like obtained by reacting an acid anhydride of a polyvalent carboxylic acid. In addition, the binder resin (B) used as a positive photosensitive black resin composition may be a phenolic hydroxyl group-containing polymer compound such as a phenol resin or a polyhydroxystyrene resin, and a methacrylic acid copolymer. A resin containing a phenolic hydroxyl group or a carboxyl group, such as a carboxyl group-containing polymer compound such as an acrylic copolymer. Further, as the resin, a curable alkali-soluble resin is preferred. The polymer compound having a curable property may, for example, be a polymer compound having a vinyl group, an epoxy group, an oxetanyl group, a tetrahydrofuranyl group or a butyrolactone skeleton. -15- 201044031 (Formation of a color pixel layer) The formation of a color pixel layer includes the step of: filling a non-crosslinkable coloring ink into an opening of a black matrix formed on a substrate in the manufacture of a black matrix substrate a first color pixel layer forming step of forming a part of the color pixel layer; a crosslinkable ink having a solid content concentration of 30% by weight or more and yielding 以下O.OlmPa or less, and contact of the crosslinkable ink with respect to the black matrix a cross-linking ink filling step of filling an opening having a non-crosslinkable colored ink and forming a part of the color pixel layer in a state where the angle is 25 degrees or less; and hardening the ink of the filling Hardening step. <First color pixel layer forming step> In the first color pixel layer forming step, the non-crosslinkable coloring ink is filled onto the opening of the black matrix 5BM formed on the black matrix substrate 7. The non-parent color ink forms part of the color pixel layer (hereinafter referred to as "first color pixel layer"). The first color pixel layer is composed of a red first color pixel layer, a green first color pixel layer, and a blue first color pixel layer of three primary color first color pixel layers. 2A and 2B are diagrams showing the steps of the first color pixel layer forming step. In the first color pixel layer forming step, as shown in FIG. 2A, the colors corresponding to the formed first color pixel layer are formed. Printing the inkjet printing inks 1 1 R, 1 1 G, 1 1 B, which are non-crosslinkable colored inks of various colors, to the black matrix 5 using heads 1 OR, 10G, and 10B for inkjet printing. B Μ the specified opening. The magnetic head for inkjet printing is not particularly limited, and a known magnetic head such as a piezoelectric type, a magnetic bubble jet (registered trademark) method, or an electrostatic method can be used, and a piezoelectric method is particularly preferable. When the inkjet printing inks 1 1 R, 1 1 G, and 1 1 B of the respective colors are printed on the predetermined openings of the black matrix 5BM, since the solid content of each color ink is limited, the black matrix is 5BM. The volume of the opening (opening area X height of the partition wall) needs to be printed by several times or more of the inkjet printing inks UR, 11G, and 11B to obtain a desired layer thickness and coloring density of 0 in the formed color pixel layer. The inkjet printing inks 1 1 R, 1 1 G, and 1 1 B of the respective colors are printed on predetermined openings of the black matrix 5BM, and when exposed to heat or light, as shown in FIG. 2B, 'corresponds to the inks printed with the respective colors. The opening of the black matrix 5 B , forms a red first color pixel layer 5R, a green first color pixel layer 5G, and a blue first 1 color pixel layer 5 Β. The contact angle of the non-parent color ink relative to the black matrix 5 Β 较 is preferably 50 degrees or less, more preferably 20 degrees or more and 50 degrees or less. From the viewpoint of the adhesion of the ink to the black matrix 5 ,, it is preferable that the contact angle is high, and when the ink repellency of the black matrix 5 高 is high, the ink is less impaired in the corner portion of the opening. • The contact angle of the ink with respect to the bottom of the opening of the black matrix 5ΒΜ is preferably 5 degrees or less. When the contact angle exceeds 5 degrees, the ink has a reduced expandability with respect to the opening portion. In particular, the ink smearability of the corner portion of the opening portion, particularly the portion having a small radius of curvature around the opening portion, is lowered. The adjustment of the contact angle of the non-crosslinkable colored ink with respect to the black matrix 5ΒΜ can be carried out by adjusting the ink composition, or can be adjusted with respect to the contact angle of the crosslinkable ink of the black matrix 5 B -17 of -17-201044031 described later. Similarly, the black matrix 5 ΒΜ is irradiated with ultraviolet rays. The charge amount of the non-crosslinkable colored ink may be adjusted according to the color density of the target as a color filter. In the case where the non-crosslinkable colored ink contains a solvent, the drying after the ink is filled may be carried out at 100 to 230 ° C for 5 to 20 minutes. Further, vacuum drying can also be performed. • Non-crosslinkable colored ink The non-crosslinkable colored ink which can be used in the present invention contains a coloring agent, and may further contain a dispersing agent and a solvent. Although it is also possible to contain a resin component such as a binder or a monomer, it is not essential as a binder or a polyfunctional monomer which is used as a high viscosity component in order to obtain an ink for producing a color filter of a high color density. The coloring agent used in the non-crosslinkable coloring ink may be a dye or a pigment. In the case where the colorant is a pigment, it may be an inorganic pigment or an organic pigment. The coloring pigment may contain a red pigment, a green pigment, a blue pigment, a yellow pigment, a cyan pigment, a magenta pigment, or the like, and may contain one type of pigment' or may contain two or more types of pigments.

The cross-linking ink is filled in a state where the contact angle with respect to the black matrix 5BM is 25 degrees or less. In the charging method, the inkjet printing method is used in the same manner as shown in Figs. 2A and 2B of the first color pixel layer forming step. The crosslinkable ink forms a part of the color pixel layer (hereinafter referred to as "second color pixel layer"), and the first color pixel layer and the second color pixel layer constitute a color pixel layer to make the crosslinkable ink The solid content concentration is 30% by weight or more. When the solid content concentration is less than 30% by weight, since the amount of the ink liquid becomes too large, the possibility of color mixture between adjacent pixels becomes high. In addition, the yield of the cross-linking ink is 〇 〇 1 m P a or less. When the yield 値 exceeds 0.01 mPa, the flatness becomes insufficient and the flatness of the color element layer is impaired.

Further, it is important to carry out the entanglement in a state where the contact angle of the crosslinkable ink with respect to the black matrix 5 B M -26 to 201044031 is 25 degrees or less. In the case where the contact angle exceeds 25 degrees, the ink droplet becomes a spherical surface (elliptical surface), and as a result, the ink of the portion far from the center of the opening portion is deteriorated in the ink, and the shape of the depression is formed to impair the flatness. Although the adjustment of the contact angle can be adjusted by the ink composition, it is preferable to irradiate the black color matrix 5 B 紫外线 with ultraviolet rays to improve the degree of freedom of the ink composition. 〇 The wavelength of the ultraviolet ray to be irradiated is preferably a wavelength containing a short-wavelength component of 300 nm or less. In the case of ultraviolet rays which do not contain ultraviolet rays of 300 nm or less, the effect of improving lyophilic properties is small. Further, as a light source for irradiating such ultraviolet rays, specifically, a light source capable of emitting a high-energy line having a wavelength of 2 〇〇 to 3 〇 〇 nm, such as a high-pressure mercury lamp, a low-pressure mercury lamp, or a xenon lamp, may be mentioned. The amount of ultraviolet rays to be irradiated is preferably 50,000 m J / c m 2 or less. The amount of ultraviolet light to be irradiated is determined by the contact angle of the ink and the light-shielding partition wall, but the irradiation effect is small when it exceeds 5 〇〇mJ/cm 2 , and can be, for example, 5 〇 to 5 〇〇 mJ/cm 2 °. If possible, it is preferably carried out within 1 hour before the cross-linking oil _ _ $ . When the ultraviolet ray is irradiated for more than one hour, the ultraviolet ray irradiation effect is gradually reduced. Therefore, in order to control the contact angle between the opaque partition wall and the ink, it is preferable to illuminate the cross-linking oil sac before the filling of the cross-linking oil sac from the viewpoint of quality control. . Incidentally, the adjustment of the contact angle of the non-crosslinkable colored ink with respect to the black matrix 5 B 之前 is performed by irradiation of ultraviolet rays, and the same conditions as described above can be employed for -27-201044031. • Crosslinkable ink The crosslinkable ink used in the present invention contains a crosslinkable monomer and an initiator or a thermal polymerization initiator, and preferably contains a crosslinkable multibody and a photopolymerization initiator, and may contain 70% by weight. % or less of solvent.
