本發明涉及一種著色劑分散液、著色劑分散液的製造方法、著色組成物、著色組成物的製造方法、著色固化膜、以及顯示元件及固體攝像元件，更詳細而言，涉及在透射型或反射型的彩色液晶顯示元件、固體攝像元件、有機電致發光(Electroluminescence，EL）顯示元件、電子紙等中所使用的著色固化膜的形成中所使用的著色組成物及其製造方法，使用該著色組成物而形成的著色固化膜，包含該著色固化膜的顯示元件及固體攝像元件，以及在該著色組成物的製備中所使用的著色劑分散液及其製造方法。The present invention relates to a coloring agent dispersion liquid, a method for producing a colorant dispersion liquid, a coloring composition, a method for producing a coloring composition, a colored cured film, and a display element and a solid-state image sensor, and more particularly, in a transmissive type or A coloring composition used for forming a color-developing film used for a reflective color liquid crystal display device, a solid-state imaging device, an organic electroluminescence (EL) display device, or an electronic paper, and a method for producing the same A colored cured film formed by coloring a composition, a display element including the colored cured film, a solid-state image sensor, and a colorant dispersion liquid used in the preparation of the colored composition, and a method for producing the same.

已知如下的方法：在使用著色感放射線性組成物而製造彩色濾光片時，在基板上塗布顏料分散型著色感放射線性組成物而進行乾燥後，對乾燥塗膜以所期望的圖案形狀照射放射線（以下稱為“曝光”），進行顯影，由此將紅色、綠色及藍色的三原色像素配置在基板上的方法（所謂的光微影法。例如參照專利文獻1～專利文獻2）。而且，還已知利用分散有碳黑的光聚合性組成物而形成黑色矩陣的方法（例如參照專利文獻3）。另外，還已知使用顏料分散型著色樹脂組成物，利用噴墨方式而獲得各色像素的方法（例如參照專利文獻4）。A method is known in which a color filter is produced by using a coloring sensitizing radiation composition, and a pigment dispersion type sensitizing radiation composition is applied onto a substrate to be dried, and then the dried coating film has a desired pattern shape. A method of illuminating radiation (hereinafter referred to as "exposure") and developing the three primary color pixels of red, green, and blue on the substrate (so-called photolithography method. For example, see Patent Documents 1 to 2) . Further, a method of forming a black matrix by using a photopolymerizable composition in which carbon black is dispersed is known (for example, see Patent Document 3). In addition, a method of obtaining a pixel of each color by an inkjet method using a pigment-dispersed colored resin composition is known (for example, see Patent Document 4).

近年來，從畫面面積比較小的個人計算機、顯示器用途，到畫面大型且要求高度的畫質的電視用途中也展開液晶顯示裝置的開發。   在電視用途中，與現有的顯示器用途相比而言，要求更高度的畫質、亦即對比度及色純度的提高。為了提高對比度，要求在形成彩色濾光片時所使用的著色固化性組成物中所使用的有機顏料的粒子尺寸更微小。而且，為了提高顯示裝置的色純度，要求著色劑（有機顏料等）在該著色固化性組成物的固體成分中所占的含有率更高。另外，自提高固體撮像裝置的分色性的觀點考慮，還要求著色劑（有機顏料等）的含有率更高。In recent years, the development of liquid crystal display devices has also been progressed from the use of personal computers and display applications having a relatively small screen area to television applications requiring large image quality and high image quality. In television applications, higher image quality, that is, contrast and color purity, is required compared to existing display applications. In order to improve the contrast, the particle size of the organic pigment used in the colored curable composition used in forming the color filter is required to be smaller. Further, in order to increase the color purity of the display device, it is required that the coloring agent (organic pigment or the like) has a higher content ratio in the solid content of the colored curable composition. Further, from the viewpoint of improving the color separation property of the solid imaging device, the content of the colorant (organic pigment or the like) is required to be higher.

對於如上所述的要求，需要使顏料的粒徑更微細化，且分散性更高的顏料分散組成物。  例如，關於由於色相良好而作為綠色像素的形成用途在近年來受到關注的溴化鋅酞菁顏料，為了提高分散性，通常在例如該酞菁顏料的表面，用其衍生物化合物對顏料表面進行改質，使用具有容易吸附於經改質的表面的極性官能基的低分子量樹脂等分散劑，實現顏料的分散性及分散穩定性，獲得含有顏料、表面改質劑、分散劑的顏料分散液。而且，使所得的顏料分散液進一步含有黏合樹脂、聚合性化合物、光聚合引發劑及其他成分而製成感光性組成物，使用其而進行利用光微影法等形成彩色濾光片的著色圖案的操作。For the above-described requirements, a pigment dispersion composition having a finer particle diameter and a higher dispersibility is required. For example, regarding a zinc bromide phthalocyanine pigment which has been attracting attention as a green pixel due to good hue in recent years, in order to improve dispersibility, the surface of the pigment is usually subjected to a derivative compound on the surface of the phthalocyanine pigment, for example. In the modification, a dispersant such as a low molecular weight resin having a polar functional group which is easily adsorbed on the surface to be modified is used to achieve dispersibility and dispersion stability of the pigment, and a pigment dispersion containing a pigment, a surface modifier, and a dispersant is obtained. . In addition, the pigment dispersion liquid further contains a binder resin, a polymerizable compound, a photopolymerization initiator, and other components to form a photosensitive composition, and a coloring pattern for forming a color filter by photolithography or the like is used. Operation.

隨著顏料微細化且顏料的含有率變高，分散變困難，為了解決該問題點，作為在彩色濾光片用感光性樹脂組成物中所使用的分散劑，提出了使用具有親溶媒性的嵌段與具有特定胺值的嵌段的丙烯酸系嵌段共聚物作為分散劑的顏料分散液（例如參照專利文獻5）。 [現有技術文獻] [專利文獻]In order to solve the problem, it is proposed to use a solvent having a resolving property as a dispersing agent used in a photosensitive resin composition for a color filter, as the pigment is made finer and the content of the pigment is increased. A pigment dispersion liquid having a block and an acrylic block copolymer having a block having a specific amine value as a dispersant (for example, see Patent Document 5).

[發明所欲解決之課題] 然而，根據本發明者等人的研究判明：使用所述專利文獻5中所記載的著色組成物而形成的綠色像素不僅耐溶劑性不足，而且在與該綠色像素鄰接而形成其他顏色的像素（例如藍色像素）時，在其他顏色像素的形成中所使用的著色組成物中的成分（例如著色劑）污染該綠色像素（以下也稱為“移染性”），或者在該綠色像素與其他顏色像素的邊界產生異物。[Problems to be Solved by the Invention] However, according to the study by the inventors of the present invention, it has been found that the green pixel formed by using the coloring composition described in Patent Document 5 is not only insufficient in solvent resistance but also in the green pixel. When pixels of other colors (for example, blue pixels) are formed adjacent to each other, components (for example, coloring agents) in the coloring composition used in formation of other color pixels contaminate the green pixels (hereinafter also referred to as "transferability"). ), or generate foreign matter at the boundary of the green pixel and other color pixels.

以下，對彩色濾光片中所使用的著色固化膜及其形成方法加以說明。Hereinafter, the colored cured film used in the color filter and a method of forming the same will be described.

作為形成構成彩色濾光片的著色固化膜的方法，首先可列舉如下方法。首先，在基板的表面上視需要以劃分形成像素的部分的方式形成遮光層（黑色矩陣）。其次，在該基板上塗布例如綠色的本發明的感放射線性著色組成物的液狀組成物後，進行預烘烤使溶媒蒸發，形成塗膜。其次，介隔光掩模對該塗膜進行曝光後，使用鹼性顯影液而進行顯影，將塗膜的未曝光部溶解除去。其後，通過進行後烘烤而形成像素陣列，所述像素陣列以規定的排列配置綠色的像素圖案（著色固化膜）。As a method of forming the colored cured film constituting the color filter, first, the following method can be mentioned. First, a light shielding layer (black matrix) is formed on the surface of the substrate in such a manner as to divide the portion where the pixels are formed. Next, a liquid composition of, for example, a green radiation sensitive coloring composition of the present invention is applied onto the substrate, and then prebaked to evaporate the solvent to form a coating film. Next, the coating film was exposed through a photomask, and then developed using an alkaline developing solution to dissolve and remove the unexposed portion of the coating film. Thereafter, a pixel array is formed by post-baking, and the pixel array is arranged in a predetermined arrangement in a green pixel pattern (colored cured film).

其次，使用紅色或藍色的各感放射線性著色組成物，與所述同樣地進行各感放射線性著色組成物的塗布、預烘烤、曝光、顯影及後烘烤，在同一基板上依序形成紅色像素陣列及藍色像素陣列。由此獲得在基板上配置紅色、綠色及藍色此三原色的像素陣列的彩色濾光片。其中，在本發明中，形成各色像素的順序並不限定於所述順序。Next, each of the radiation-sensitive coloring compositions of red or blue is used, and coating, prebaking, exposure, development, and post-baking of the respective radiation-sensitive coloring compositions are performed in the same manner as described above, sequentially on the same substrate. A red pixel array and a blue pixel array are formed. Thus, a color filter in which a pixel array of three primary colors of red, green, and blue is disposed on the substrate is obtained. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the order.

而且，黑色矩陣可通過利用光微影法，將通過濺鍍或蒸鍍而形成的鉻等的金屬薄膜製成所期望的圖案而形成，但也可以使用分散有黑色顏料的感放射線性著色組成物，與形成所述像素的情況同樣地進行而形成。Further, the black matrix can be formed by forming a metal film such as chromium formed by sputtering or vapor deposition into a desired pattern by photolithography, but it is also possible to use a radiation-sensitive coloring composition in which a black pigment is dispersed. The object is formed in the same manner as in the case of forming the pixel.

形成著色固化膜時所使用的基板例如可列舉玻璃、矽、聚碳酸酯、聚酯、芳香族聚醯胺、聚醯胺醯亞胺、聚醯亞胺等。Examples of the substrate used for forming the colored cured film include glass, ruthenium, polycarbonate, polyester, aromatic polyamide, polyamidimide, and polyimide.

而且，在這些基板上，還可以視需要預先實施利用矽烷偶聯劑等的化學品處理、等離子體處理、離子鍍、濺鍍、氣相反應法、真空蒸鍍等適當的預處理。Further, on these substrates, an appropriate pretreatment such as chemical treatment such as a decane coupling agent, plasma treatment, ion plating, sputtering, gas phase reaction, or vacuum vapor deposition may be performed in advance.

在將感放射線性著色組成物塗布於基板時，可採用噴霧法、輥塗法、旋轉塗布法（旋塗法）、狹縫模塗布法（狹縫塗布法）、棒塗法等適宜的塗布法，特別是優選採用旋塗法、狹縫模塗布法。When the radiation sensitive coloring composition is applied to a substrate, suitable coating such as a spray method, a roll coating method, a spin coating method (spin coating method), a slit die coating method (slit coating method), or a bar coating method can be employed. The method is particularly preferably a spin coating method or a slit die coating method.

An aqueous solution of undecene, 1,5-diazabicyclo-[4.3.0]-5-nonene or the like.

在鹼性顯影液中還可以適量添加例如甲醇、乙醇等水溶性有機溶劑或表面活性劑等。另外，堿顯影後通常進行水洗。A water-soluble organic solvent such as methanol or ethanol, a surfactant, or the like may be added to the alkaline developer in an appropriate amount. In addition, water is usually washed after development.

顯影處理法可應用噴淋顯影法、噴霧顯影法、浸漬（dip）顯影法、水坑式（覆液）顯影法等。顯影條件優選在常溫下為5秒～300秒。As the development treatment method, a shower development method, a spray development method, a dip development method, a puddle type (liquid coating) development method, or the like can be applied. The developing conditions are preferably from 5 seconds to 300 seconds at normal temperature.

後烘烤的條件通常是在180℃～280℃下為10分鐘～60分鐘左右。The post-baking conditions are usually from about 10 minutes to about 60 minutes at 180 to 280 °C.

關於如上所述而形成的像素的膜厚，在製成顯示元件中所使用的彩色濾光片的著色固化膜的情況下為0.5 μm～8 μm，優選為1 μm～4 μm。而且在製成固體攝像元件中所使用的彩色濾光片的著色固化膜的情況下通常為0.3 μm～4 μm、優選為0.5 μm～2 μm。The film thickness of the pixel formed as described above is 0.5 μm to 8 μm, preferably 1 μm to 4 μm, in the case of a colored cured film of a color filter used for a display element. Further, in the case of a colored cured film of a color filter used for a solid-state image sensor, it is usually 0.3 μm to 4 μm, preferably 0.5 μm to 2 μm.

而且，作為形成構成彩色濾光片的著色固化膜的第二方法，可採用日本專利特開平7-318723號公報、日本專利特開2000-310706號公報等中所揭示的利用噴墨方式而獲得各色像素的方法。在該方法中，首先在基板表面上形成兼具遮光功能的隔板。其次，在所形成的隔板內，利用噴墨裝置而噴出例如綠色的本發明的熱固性著色組成物的液狀組成物後，進行預烘烤而使溶媒蒸發。其次，視需要對該塗膜進行曝光後，進行後烘烤，藉此使其固化而形成綠色像素圖案。Further, as a second method of forming the colored cured film constituting the color filter, the ink jet method can be used as disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. The method of each color pixel. In this method, first, a separator having a light blocking function is formed on the surface of the substrate. Next, in the formed separator, for example, a green liquid composition of the thermosetting coloring composition of the present invention is ejected by an inkjet device, and then prebaked to evaporate the solvent. Next, the coating film is exposed as needed, and post-baking is performed to cure it to form a green pixel pattern.

其次，使用紅色或藍色的各熱固性著色組成物，與所述同樣地進行而在同一基板上依序形成紅色像素圖案及藍色像素圖案。由此獲得在基板上配置有紅色、綠色及藍色此三原色的像素圖案的彩色濾光片。然而，在本發明中，形成各色像素的順序並不限定於上述。Next, each of the red or blue thermosetting coloring compositions was used, and the red pixel pattern and the blue pixel pattern were sequentially formed on the same substrate in the same manner as described above. Thus, a color filter in which pixel patterns of three primary colors of red, green, and blue are disposed on the substrate is obtained. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the above.

另外，隔板不僅僅起到遮光功能，還起到用以使噴出至劃分內的各色熱固性著色組成物並不混色的功能，因此與在所述第一方法中所使用的黑色矩陣相比而言，膜厚較厚。因此，隔板通常使用黑色感放射線性組成物而形成。In addition, the separator not only functions as a light-shielding function, but also functions to prevent the color-fixing coloring compositions discharged into the division from being mixed, and thus is compared with the black matrix used in the first method. The film thickness is thicker. Therefore, the separator is usually formed using a black radiation-sensitive composition.

形成著色固化膜時所使用的基板及放射線的光源、以及預烘烤及後烘烤的方法、條件與所述第一方法相同。如上所述地進行，利用噴墨方式而形成的像素的膜厚與隔板的高度為同等程度。The substrate and the light source used for forming the colored cured film, and the methods and conditions for prebaking and postbaking are the same as those of the first method. As described above, the film thickness of the pixel formed by the inkjet method is equivalent to the height of the spacer.

在如上所述而獲得的像素圖案上視需要形成保護膜後，利用濺鍍而形成透明導電膜。在形成透明導電膜後，還可以進一步形成間隔物而製成彩色濾光片。通常使用感放射線性組成物來形成間隔物，但亦可製成具有遮光性的間隔物（黑色間隔物）。在這種情況下，使用分散有黑色著色劑的著色感放射線性組成物。After the protective film is formed as needed on the pixel pattern obtained as described above, a transparent conductive film is formed by sputtering. After the transparent conductive film is formed, a spacer may be further formed to form a color filter. A spacer is usually formed using a radiation-sensitive composition, but a spacer having a light-shielding property (black spacer) can also be formed. In this case, a color-sensitive radiation composition in which a black colorant is dispersed is used.

包含如上所述而形成的本發明的著色固化膜的彩色濾光片由於耐溶劑性優異、且可解除鄰接而形成其他顏色的像素時的移染性的問題或異物的產生，因此在彩色液晶顯示元件、彩色攝像管元件、彩色傳感器、有機EL顯示元件、電子紙、固體攝像元件等中極其有用。The color filter including the colored cured film of the present invention formed as described above is excellent in solvent resistance, and can solve the problem of transfer property or the generation of foreign matter when pixels of other colors are formed adjacent to each other. It is extremely useful for display elements, color image sensor elements, color sensors, organic EL display elements, electronic paper, solid-state imaging elements, and the like.

包含本發明的著色固化膜的彩色液晶顯示元件可以是透射型也可以是反射型，可採用適當的結構。例如可以採用在與配置薄膜晶體管（Thin Film Transistor，TFT）的驅動用基板不同的基板上形成彩色濾光片，驅動用基板與形成了彩色濾光片的基板介隔液晶層而對向的結構，還可以採用在配置有薄膜晶體管（TFT）的驅動用基板的表面上形成彩色濾光片的基板、與形成有ITO（摻雜有錫的氧化銦（indium tin oxide））電極的基板介隔液晶層而對向的結構。後者的結構具有可使開口率明顯提高，從而獲得明亮的高精細的液晶顯示元件的優點。另外，在採用後者的結構的情況下，黑色矩陣或黑色間隔物可以形成在形成有彩色濾光片的基板側、以及形成有ITO電極的基板側的任一側。The color liquid crystal display element including the colored cured film of the present invention may be of a transmissive type or a reflective type, and an appropriate structure may be employed.

特別是本發明的顯示元件優選為包含本發明的著色固化膜、與含有酸性染料的著色固化膜的顯示元件。更優選本發明的顯示元件包含第一著色固化膜、第二著色固化膜及第三著色固化膜，第一著色固化膜是使用本發明的著色組成物而形成，第二著色固化膜是使用含有酸性染料的著色組成物而形成。進一步更優選為如下顯示元件，其包含使用本發明的著色組成物而形成的第一著色固化膜、與第一著色固化膜鄰接且含有酸性染料的第二著色固化膜、以及第三著色固化膜。自製成色度特性優異的顯示元件的觀點考慮，優選此種形態。另外，在本發明中所謂“酸性染料”是指陰離子部成為發色團（chromophore）的離子性染料，是構成發色團的陰離子部與抗衡陽離子形成鹽的化合物。In particular, the display element of the present invention is preferably a display element comprising the colored cured film of the present invention and a colored cured film containing an acid dye. More preferably, the display element of the present invention comprises a first colored cured film, a second colored cured film, and a third colored cured film, wherein the first colored cured film is formed using the colored composition of the present invention, and the second colored cured film is used. It is formed by the colored composition of the acid dye. Further more preferably, it is a display element comprising a first colored cured film formed using the colored composition of the present invention, a second colored cured film adjacent to the first colored cured film and containing an acid dye, and a third colored cured film . Such a form is preferable from the viewpoint of producing a display element excellent in chromaticity characteristics. In the present invention, the term "acid dye" means an ionic dye in which an anion portion is a chromophore, and is a compound which forms a salt between an anion portion constituting a chromophore and a counter cation.

其理由尚不確定，但本發明者等人如下所述地進行推測。例如在包含使用第二著色組成物而形成的第二著色固化膜的基板上塗布第一著色組成物時，第一著色組成物自第二著色固化膜的最表面滲入，存在第二著色固化膜中所含的著色劑或分散劑等成分與第一著色組成物中所含的著色劑或分散劑等成分產生相互作用的可能性。更具體而言，在第二著色固化膜中含有酸性染料、且第一著色組成物中含有顏料及具有胺基的分散劑的情況下，存在所述酸性染料與所述具有胺基的分散劑進行鹽交換的可能性。所述具有胺基的分散劑本來是有助於第一著色組成物中所含的顏料的分散的成分，但由於與所述酸性染料進行鹽交換而造成對所述顏料的分散做出貢獻的分散劑的量減少，從而存在損及顏料的分散穩定性的可能性。其結果，顏料作為異物而析出，從而存在顯示元件的色度特性降低的可能性。The reason for this is not certain, but the inventors of the present invention have estimated as follows. For example, when the first coloring composition is applied onto the substrate including the second colored cured film formed using the second colored composition, the first colored composition penetrates from the outermost surface of the second colored cured film, and the second colored cured film is present. The components such as the coloring agent or the dispersing agent contained in the first coloring composition may interact with components such as a coloring agent or a dispersing agent. More specifically, in the case where the second colored cured film contains an acid dye and the first colored composition contains a pigment and a dispersant having an amine group, the acid dye and the dispersant having an amine group are present. The possibility of salt exchange. The dispersant having an amine group is originally a component which contributes to dispersion of the pigment contained in the first coloring composition, but contributes to dispersion of the pigment due to salt exchange with the acid dye. The amount of the dispersant is reduced, so that there is a possibility of impairing the dispersion stability of the pigment. As a result, the pigment is precipitated as a foreign matter, and there is a possibility that the chromaticity characteristics of the display element are lowered.

認為在本發明的著色組成物中所含的分散劑（b1）及分散劑（b2）中，胺值高的分散劑（b1）與顏料的相互作用強。因此，在使用本發明的著色組成物作為所述第一著色組成物的情況下，與顏料的相互作用更弱的分散劑（b2）優先與酸性染料進行鹽交換，由分散劑（b1）確保顏料的分散穩定性，因此顏料難以作為異物而析出。 優選分散劑（b1）的胺值Y（mgKOH/g）及分散劑（b2）的胺值X（mgKOH/g）滿足以下關係。 自形成移染性優異的著色固化膜的觀點考慮，優選Y+X≧190。自使與鄰接的其他顏色的像素的邊界的異物產生變少的觀點考慮，優選Y-X≧50。另外，在使用胺值相互不同的兩種以上分散劑（b1）的情況及使用胺值相互不同的兩種以上分散劑（b2）的情況的“Y+X”及“Y-X”的計算中，應用含量最多的分散劑（b1）的胺值與含量最多的分散劑（b2）的胺值。 第一著色固化膜、第二著色固化膜及第三著色固化膜可以是紅色、綠色及藍色的組合，也可以是黃色、青色及洋紅色的組合。而且，例如可以是第一著色固化膜為紅色固化膜、第二著色固化膜為綠色固化膜、第三著色固化膜為藍色固化膜，也可以是第一著色固化膜為藍色固化膜、第二著色固化膜為紅色固化膜、第三著色固化膜為綠色固化膜。其中，優選包含使用含有鹵化金屬酞菁顏料的本發明的著色組成物而形成的綠色固化膜、及含有酸性染料的紅色固化膜或藍色固化膜的顯示元件。In the dispersing agent (b1) and the dispersing agent (b2) contained in the coloring composition of the present invention, it is considered that the dispersing agent (b1) having a high amine value has a strong interaction with the pigment. Therefore, in the case where the colored composition of the present invention is used as the first coloring composition, the dispersing agent (b2) having a weaker interaction with the pigment preferentially undergoes salt exchange with the acid dye, and is ensured by the dispersing agent (b1). Since the pigment has a dispersion stability, it is difficult for the pigment to precipitate as a foreign matter. The amine value Y (mgKOH/g) of the dispersing agent (b1) and the amine value X (mgKOH/g) of the dispersing agent (b2) preferably satisfy the following relationship. From the viewpoint of forming a colored cured film excellent in transferability, Y+X≧190 is preferable. From the viewpoint of reducing the amount of foreign matter at the boundary of adjacent pixels of other colors, Y-X 50 is preferable. In addition, in the case of using two or more types of dispersing agents (b1) having different amine values and the calculation of "Y+X" and "YX" in the case of using two or more kinds of dispersing agents (b2) having different amine values, The amine value of the most dispersed dispersant (b1) and the amine content of the most dispersed dispersant (b2). The first colored cured film, the second colored cured film, and the third colored cured film may be a combination of red, green, and blue, or may be a combination of yellow, cyan, and magenta. Further, for example, the first colored cured film may be a red cured film, the second colored cured film may be a green cured film, and the third colored cured film may be a blue cured film, or the first colored cured film may be a blue cured film. The second colored cured film is a red cured film, and the third colored cured film is a green cured film.

The prebaking was carried out to form a coating film having a film thickness of 2.5 μm. Next, after the substrate was cooled to room temperature, radiation of respective wavelengths of 365 nm, 405 nm, and 436 nm was exposed to the coating film at a exposure amount of 400 J/m 2 using a high pressure mercury lamp through a photomask. Thereafter, for each of the substrates, a developing solution containing a 0.04% by mass aqueous potassium hydroxide solution at 23 ° C was sprayed at a developing pressure of 1 kgf/cm 2 (nozzle diameter: 1 mm), thereby performing shower development for 60 seconds. Thereafter, the substrate was washed with ultrapure water, air-dried, and further baked in a dust-free oven at 220 ° C for 30 minutes to form a pixel array in which green striped pixel patterns were arranged on the substrate. The average surface roughness (smoothness of the pattern surface) of the upper portion of the obtained pixel pattern was measured using an atomic force microscope manufactured by a digital instrument (Digital Instruments), and the case where the average surface roughness was 30 Å or less was evaluated as "A". When it is more than 30 Å and 50 Å or less, it is evaluated as "B", and when it exceeds 50 Å, it is evaluated as "C". The results are shown in Tables 4 to 5.
