＜< 彩色濾光片Color filter ＞＞

本發明的其他態樣的彩色濾光片包含上述的著色感光性樹脂組合物的固化物，從而具有在製造製程中的後烘烤步驟之前能夠將圖案的形狀製造成正斜面的形態從而防止製造製程中產生問題，且能夠防止形成圖案時在圖案中產生孔（hole）等優點。The color filter according to another aspect of the present invention includes the cured product of the colored photosensitive resin composition described above, and thus has a shape capable of producing a shape of a bevel before the post-baking step in the manufacturing process, thereby preventing the manufacturing process. In this way, problems can be caused and holes can be prevented from being formed in the pattern when the pattern is formed.

本發明的彩色濾光片可無限制地使用本領域通常使用的製造方法來製造，作為一實例，可參照第1圖至第3圖來進行說明，具體如下。The color filter of the present invention can be manufactured without limitation using a manufacturing method generally used in the art. As an example, the color filter can be described with reference to FIGS. 1 to 3, as follows.

為了利用本發明的著色感光性樹脂組合物來製造彩色濾光片，需要形成著色圖案，為此，將上述著色感光性樹脂組合物進行圖案處理。具體而言，參照第1圖，使由本發明的著色感光性樹脂組合物形成的顏色層11形成於基板10上部。此時，上述基板10的種類沒有特別限定，可為彩色濾光片自身基板，也可為顯示裝置等中彩色濾光片所處的部位。上述基板10可為玻璃板、矽晶圓以及聚醚碸 （poly ether sulfone，PES）、聚碳酸酯（poly carbonate，PC）等塑膠板等。即，上述基板10可為矽（Si）、矽氧化物（SiOx）或玻璃基板，或者可為高分子基板。這樣，為了使由著色感光性樹脂組合物組成的顏色層11形成於基板10上，例如將由溶劑稀釋的著色感光性樹脂組合物藉由旋塗、狹縫式旋塗、狹縫式塗佈、輥塗、噴霧、噴墨方式等塗佈方法而塗佈於基板上，然後使溶劑等揮發性成分揮發。由此，形成由著色感光性樹脂組合物組成的顏色層11，上述顏色層11由著色感光性樹脂組合物的固體成分組成，幾乎不含有揮發性成分。膜面的厚度係依據組合物的黏度、固體成分的濃度、塗佈速度等塗佈條件來確定，在使用本發明的組合物的情況下，可得到厚度為0.5至5微米的顏色層11。In order to manufacture a color filter using the colored photosensitive resin composition of the present invention, it is necessary to form a colored pattern. To this end, the above-mentioned colored photosensitive resin composition is patterned. Specifically, referring to FIG. 1, a color layer 11 formed of the colored photosensitive resin composition of the present invention is formed on the substrate 10. At this time, the type of the substrate 10 is not particularly limited, and may be a substrate of the color filter itself, or a portion where the color filter is located in a display device or the like. The substrate 10 may be a glass plate, a silicon wafer, a plastic plate such as polyether sulfone (PES), polycarbonate (poly carbonate, PC), or the like. That is, the substrate 10 may be a silicon (Si), silicon oxide (SiOx), or glass substrate, or may be a polymer substrate. In this way, in order to form the color layer 11 composed of the colored photosensitive resin composition on the substrate 10, the colored photosensitive resin composition diluted with a solvent is spin-coated, slit-type spin-coated, slit-type applied, The coating method such as roll coating, spraying, and inkjet method is applied to a substrate, and then volatile components such as a solvent are volatilized. Thereby, a color layer 11 composed of a colored photosensitive resin composition is formed. The color layer 11 is composed of a solid component of the colored photosensitive resin composition and contains almost no volatile components. The thickness of the film surface is determined according to the coating conditions such as the viscosity of the composition, the concentration of the solid content, and the coating speed. When the composition of the present invention is used, a color layer 11 having a thickness of 0.5 to 5 microns can be obtained.

接著，參照第2圖，使在基材10上由著色感光性樹脂組合物形成的顏色層11曝露於光30（曝光）。為了曝光，例如將上述顏色層11透過光罩20以預定圖案照射光30。此時，作為光30，通常使用紫外線的g線（波長：436奈米）、h線、i線（波長：365奈米）等。光30按照光罩20的圖案通過。上述光罩20提供在玻璃板的表面上以預定的圖案遮擋光線的遮光層。光30會被遮光層遮擋。沒有提供該遮光層的玻璃板的部分為透過光線的透光部。按照這樣的透光部的圖案，使上述顏色層11曝光。光30的照射量係根據所使用的著色感光性樹脂組合物而進行適當選擇。Next, referring to FIG. 2, the color layer 11 formed of the colored photosensitive resin composition on the substrate 10 is exposed to light 30 (exposure). For exposure, for example, the color layer 11 is irradiated with light 30 in a predetermined pattern through the mask 20. At this time, as the light 30, g-line (wavelength: 436 nm), h-line, i-line (wavelength: 365 nm), etc. of ultraviolet rays are generally used. The light 30 passes in accordance with the pattern of the mask 20. The photomask 20 described above provides a light-shielding layer that blocks light in a predetermined pattern on the surface of the glass plate. The light 30 is blocked by the light shielding layer. The portion of the glass plate on which the light shielding layer is not provided is a light transmitting portion that transmits light. The color layer 11 is exposed in accordance with such a pattern of the light transmitting portion. The irradiation amount of the light 30 is appropriately selected according to the coloring photosensitive resin composition used.

經上述光30照射的部分與沒有被光30照射的部分相比溶解度顯著變小，二者的溶解度差異極大化，因此利用這樣的差異來進行顯影作業。為了顯影，例如使曝光後的著色感光性樹脂組合物層浸漬於顯影劑。作為顯影劑，使用鹼化合物、比如碳酸鈉、氫氧化鈉、氫氧化鉀、碳酸鉀、四甲基氫氧化銨等的水溶液。參照第3圖，藉由這樣的顯影，將形成於基板10上的顏色層11中沒有被光30照射的光30未照射區域去除。與此相反，經光30照射的光30照射區域殘留而組成著色圖案11R。顯影後，通常用水清洗上述層並乾燥，得到預定的著色圖案11R。此外，乾燥後，也可實施加熱處理。經加熱處理而形成的著色圖案11R發生固化，由此提高機械強度。如此，由於能夠藉由加熱處理提高著色圖案11R的機械強度，因此較佳使用含有固化劑的著色感光性組合物。加熱溫度通常為180℃以上，較佳為200至250℃。The solubility of the portion irradiated with the light 30 is significantly smaller than that of the portion not irradiated with the light 30, and the difference in solubility between the two is extremely large. Therefore, the development is performed using such a difference. For the development, for example, the colored photosensitive resin composition layer after exposure is immersed in a developer. As the developer, an aqueous solution of an alkali compound such as sodium carbonate, sodium hydroxide, potassium hydroxide, potassium carbonate, tetramethylammonium hydroxide, or the like is used. Referring to FIG. 3, the light 30 unirradiated area in the color layer 11 formed on the substrate 10 that is not irradiated with the light 30 is removed by such development. In contrast, the light-irradiated area irradiated with the light 30 remains and forms the colored pattern 11R. After development, the above layer is usually washed with water and dried to obtain a predetermined coloring pattern 11R. After drying, heat treatment may be performed. The colored pattern 11R formed by the heat treatment is cured, thereby improving the mechanical strength. In this way, since the mechanical strength of the colored pattern 11R can be improved by heat treatment, it is preferable to use a colored photosensitive composition containing a curing agent. The heating temperature is usually 180 ° C or higher, and preferably 200 to 250 ° C.
