Red, ultramarine, Prussian blue, chrome oxide green, cobalt green, amber, titanium black, synthetic iron black, carbon black, and the like. In the present invention, the (a 1 ) pigment can also be used by recrystallization, reprecipitation, solvent washing, sublimation, vacuum heating or a combination thereof. Further, the (a 1 ) pigment may be used by modifying the surface of the particles with a resin as needed. For example, a resin resin described in JP-A-2001-108817 or a commercially available resin for dispersing various pigments is used as the resin for modifying the surface of the particles of the (a1) pigment. For the method of coating the surface of the carbon black, for example, the method described in JP-A-9-7, 1733, JP-A-9-95625, and JP-A-9-124969 can be used. Further, as the organic pigment, it is preferred to use a so-called salt mill (s a·11 m i 11 i n g) to refine the primary particles. As a method of salt milling, for example, the method disclosed in Japanese Laid-Open Patent Publication No. Hei 8-179丨n can be employed.

塗膜之未曝光部溶解除去。之後，藉由進行後烘烤，形成 將紅色的像素圖案以既定的排列予以配置之像素陣列。 接著，使用綠色或藍色之各著色感放射線性組成物， 與上述同樣地進行，進行各著色感放射線性組成物之塗 布、預烘烤、曝光、顯影以及後烘烤，依序在同一基板上 形成綠色之像素陣列及藍色之像素陣列。藉此，可製得將 -39- 201142500 紅色、綠色及藍色之三原色的像素陣列配置在基板上之彩 色濾光片。但是，在本發明中，各色像素之形成順序，並 未限定於上述者。 又’黑色矩陣，能藉由將以濺鍍或蒸鍍成膜之鉻等的 金屬薄膜’利用光微影法作成所要之圖案來形成，亦能使 用分散有黑色顏料的著色感放射線性組成物，與形成上述 像素的情況同樣地形成。 作爲在形成彩色濾光片之際所使用之基板，例如，能 舉出：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。 又’在這些基板’亦能依所需’而先實施矽烷耦合劑 等之藥品處理、電漿處理、離子鏟敷、濺鍍、氣相反應法、 真空蒸鍍等之適宜的前處理。 在將著色感放射線性組成物塗布在基板上之際，能採 用噴霧法（spray method)、輥塗法、旋轉塗布法（spinc〇at method)、狹縫模塗布法、棒塗布法等適宜的塗布法，但特 佳爲旋轉塗布法、狹縫模塗布法。 預烘烤’通常是組合減壓乾燥與加熱乾燥進行。減壓 乾無，通吊疋進订至達到50~200Pa爲止。又，加熱乾燥之 條件，通常是在70-110 °C下進行1〜1〇分鐘左右。 塗布厚度’作爲乾燥後之膜厚，通常是〇.6〜8 ()" m， 較佳爲1.2〜5.0# m。 作爲在形成像素及/或黑色矩陣之際所使用之放射線 -40- 201142500 光源，例如，能舉出：氙燈、鹵素燈、鎢燈、高壓水銀燈、 超高壓水銀燈、金屬鹵素燈、中壓水銀燈、低壓水銀燈等

、l,8-二氮雜雙環-[5·4.0^7-十一烯、l，5-二氮雜雙環-[4·3·0]-5-壬烯等之水溶液。 在上述鹼顯影液，例如，亦能適量添加甲醇、乙醇等 水溶性有機溶劑或界面活性劑等。又，鹼顯影後，通常進 行水洗。 · 作爲顯影處理法，能應用噴淋顯影法、噴霧顯影法、 浸漬（dip )顯影法、混拌（puddle )(盛液）顯影法等。 顯影條件，較佳爲常溫下5〜3 0 0秒。 後烘烤的條件，通常是在180〜280°C下進行10〜60分鐘 左右。 依此方式所形成之像素的膜厚，通常爲〇.5~5.0y m， 較佳爲1.0〜3.0ym。 又’作爲製造彩色濾光片之第二方法，能採用揭示於 曰本特開平7 - 3 1 8 7 2 3號公報、日本特開2000-3 1 0706號公 報等之利用噴墨方式製得各色像素的方法。在此方法中， -41- 201142500

圖案配置在基板上之彩色濾光片。但是，在本發明中，形 成各色像素的順序不限定於上述者。 又，上述隔牆，不僅有遮光功能，亦發揮讓已吐出在 劃分區域內之各色著色組成物不會混色之功能，因此相較 於在上述第一方法所使用之黑色矩陣，膜厚厚。因此，隔 牆，通常是使用黑色感放射線性組成物形成。 在形成彩色濾光片之際所使用之基板或放射線的光 源，又，預烘烤或後烘烤之方法或條件，係與上述第一方 法相同。依此方式，利用噴墨方式所形成之像素的膜厚， 係與黑色矩陣的厚度相同程度。 在依此方式所製得之像素圖案上，依需要在形成保護 膜後，利用濺鍍形成透明導電膜。亦能在形成透明導電膜 後’進一歩形成間隙物（spacer)作成彩色濾光片。間隙物， 通常是使用感放射線性組成物形成，亦能作成具有遮光性 之間隙物（黑色間隙物（b 1 a c k s p a c e r ))。在此情況，可 -42- 201142500 用分散有黑色著色劑之著色感放射線性組成物，但本發明 之著色組成物，亦能適合使用於黑色間隙物之形成。 依此方式所製得之本發明的彩色濾光片，輝度及色純 度極高，因此對於彩色液晶顯示元件、彩色攝像管元件、 彩色感測器、有機EL顯示元件、電子紙等而言極爲有用。 顯示元件 本發明之顯示元件，係具備本發明之彩色濾光片者。 作爲顯示元件，能舉出彩色液晶顯示元件、有機EL顯示元 件、電子紙等。

Color filter and method for producing the same The color filter of the present invention is provided with a coloring layer formed using the coloring composition of the present invention. As a method of manufacturing a color filter, the first method is as follows. First, on the surface of the substrate, a light shielding layer (black matrix) is formed in such a manner as to divide the portion where the pixels are formed. Next, on the substrate, for example, after applying a liquid composition in which the radiation-sensitive composition of the red pigment has been dispersed, pre-baking is performed to evaporate the solvent to form a coating film. Next, after the coating film was exposed to the reticle, development was carried out using an alkali developing solution to dissolve and remove the unexposed portion of the coating film. Thereafter, by performing post-baking, a pixel array in which red pixel patterns are arranged in a predetermined arrangement is formed. Next, using a coloring composition of green or blue coloring, the coating, prebaking, exposure, development, and post-baking of each coloring radiation composition are carried out in the same manner as described above, sequentially on the same substrate. A green pixel array and a blue pixel array are formed thereon. Thereby, a color filter in which a pixel array of three primary colors of red, green, and blue of -39 to 201142500 is disposed on the substrate can be obtained. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the above. Further, a 'black matrix can be formed by forming a desired pattern by a photolithography method using a metal thin film of chromium or the like which is formed by sputtering or vapor deposition, and a color-sensing radioactive composition in which a black pigment is dispersed can also be used. This is formed in the same manner as the case of forming the above-described pixels. Examples of the substrate used in forming the color filter include glass, enamel, polycarbonate 'polyester, aromatic polyamine, polyamidimide, polyimine, and the like. Further, in these substrates, an appropriate pretreatment such as a drug treatment such as a decane coupling agent, a plasma treatment, an ion coating, a sputtering, a gas phase reaction method, or a vacuum vapor deposition can be carried out as needed. When the coloring sensitizing radiation composition is applied onto a substrate, a spray method, a roll coating method, a spin coating method, a slit die coating method, a bar coating method, or the like can be used. The coating method is particularly preferably a spin coating method or a slit die coating method. The pre-baking is usually carried out by a combination of vacuum drying and heat drying. Decompression is dry, and the sling is ordered until it reaches 50~200Pa. Further, the conditions of heat drying are usually carried out at 70 to 110 ° C for about 1 to 1 minute. Coating thickness 'as the film thickness after drying, usually 〇. 6~8 ()" m, preferably 1. 2~5. 0# m. As the radiation source of the radiation-40-201142500 used in forming the pixel and/or the black matrix, for example, a xenon lamp, a halogen lamp, a tungsten lamp, a high pressure mercury lamp, an ultrahigh pressure mercury lamp, a metal halide lamp, a medium pressure mercury lamp, A light source such as a low-pressure mercury lamp or a laser source such as an argon ion laser, a YAG laser, a XeCl excimer laser, or a nitrogen laser, but preferably a radiation having a wavelength in the range of 190 to 450 nm. The exposure amount of the radiation is, in general, preferably 10 to 10,000 Å/m2. Further, as the alkali developing solution, for example, sodium carbonate, sodium hydroxide, potassium hydroxide, tetramethylammonium hydroxide, choline or 1,8-diazabicyclo-[5·4 is preferred. . An aqueous solution of 0^7-undecene, l,5-diazabicyclo-[4·3·0]-5-decene. In the above alkali developing solution, for example, a water-soluble organic solvent such as methanol or ethanol or a surfactant may be added in an appropriate amount. Further, after alkali development, water washing is usually carried out. As the development processing method, a shower development method, a spray development method, a dip development method, a puddle development method, or the like can be applied. The developing conditions are preferably 5 to 300 seconds at normal temperature. The post-baking conditions are usually carried out at 180 to 280 ° C for about 10 to 60 minutes. The film thickness of the pixel formed in this way is usually 〇. 5~5. 0y m, preferably 1. 0~3. 0ym. In addition, the second method of producing a color filter can be obtained by an inkjet method, which is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2000-3. The method of each color pixel. In this method, -41- 201142500 First, a partition wall having a light-shielding function is formed on the surface of the substrate. Then, in the partition wall formed, for example, a liquid composition in which the colored composition of the red pigment has been dispersed is discharged by an ink jet device, and then prebaked to evaporate the solvent. Next, the coating film is exposed as needed, and then cured by post-baking to form a red pixel pattern. Then, each of the colored compositions of green or blue was used in the same manner as described above, and a green pixel pattern and a blue pixel pattern were sequentially formed on the same substrate. Thereby, a color filter in which pixel patterns of three primary colors of red, green, and blue are arranged on the substrate can be obtained. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the above. Further, the partition wall has a function of not only a light-shielding function but also a coloring composition of each color which has been discharged in the divided area, and the film thickness is thicker than that of the black matrix used in the first method. Therefore, the partition wall is usually formed using a black radiation linear composition. The method or condition for pre-baking or post-baking of the substrate or the radiation source used in forming the color filter is the same as the first method described above. In this manner, the film thickness of the pixel formed by the ink jet method is approximately the same as the thickness of the black matrix. In the pixel pattern obtained in this manner, a transparent conductive film is formed by sputtering after forming a protective film as needed. It is also possible to form a color filter by forming a spacer after forming a transparent conductive film. The spacers are usually formed using a radiation-sensitive composition, and can also be formed into a light-shielding spacer (b 1 a c k s p a c e r ). In this case, the color-sensitive linear composition in which the black colorant is dispersed may be used in the case of -42 to 201142500, but the colored composition of the present invention can also be suitably used for the formation of a black spacer. The color filter of the present invention produced in this manner has extremely high luminance and color purity, and thus is extremely excellent for a color liquid crystal display element, a color image pickup device element, a color sensor, an organic EL display element, an electronic paper, and the like. it works.

Examples of the display element include a color liquid crystal display element, an organic EL display element, and electronic paper.

Further, it is also possible to adopt a substrate in which a color light-receiving sheet is formed on a surface of a driving substrate on which a thin film transistor (TFT) is disposed, and an ITO (tin-doped indium oxide) electrode is formed to face the liquid crystal layer. structure. The latter structure has the advantage that the aperture ratio can be remarkably improved, and a bright and high-definition liquid crystal display element can be obtained.
