Resin boards such as ethylene diformate are formed by forming aluminum, silver, silver/copper/palladium alloy thin films on silicon or the above-mentioned substrates. On these substrates, other color filter layers, resin layers, transistors, circuits, etc. may also be formed. In addition, a substrate obtained by subjecting a silicon substrate to HMDS (hexamethyldisilazane) treatment may also be used.

利用光微影法之各顏色像素之形成可藉由公知或慣用之裝置或條件進行。例如,可按照下述之方式製作。首先,藉由將紅色著色組合物塗佈於基板上,進行加熱乾燥(預烘烤)及/或減壓乾燥而去除溶劑等揮發成分使其乾燥,獲得平滑之組合物層。作為塗佈方法,可例舉:旋轉塗佈法、狹縫式塗佈法、狹縫旋轉塗佈(slit and spin coat)法等。進行加熱乾燥之情形時之溫度較佳為30~120℃,更佳為50~110℃。又,作為加熱時間,較佳為10秒~60分鐘,更佳為30秒~30分鐘。於進行減壓乾燥之情形時,較佳為於50~150 Pa之壓力下、於20~25℃之溫度範圍內進行。組合物層之膜厚並無特別限定,根據目標之彩色濾光片之膜厚適當選擇即可。The formation of pixels of each color by photolithography can be carried out by known or commonly used devices or conditions. For example, it can be produced as follows. First, a red coloring composition is coated on a substrate, and then heat-dried (pre-baked) and/or reduced-pressure dried to remove volatile components such as solvents and dried to obtain a smooth composition layer. As a coating method, a spin coat method, a slit coat method, a slit and spin coat method, etc. are mentioned. The temperature at the time of heat-drying becomes like this. Preferably it is 30-120 degreeC, More preferably, it is 50-110 degreeC. Moreover, as heating time, it is preferable that it is 10 seconds - 60 minutes, and it is more preferable that it is 30 seconds - 30 minutes. When performing reduced-pressure drying, it is preferable to carry out under the pressure of 50-150 Pa, and to carry out in the temperature range of 20-25 degreeC. The film thickness of the composition layer is not particularly limited, and may be appropriately selected according to the film thickness of the intended color filter.

The pattern on the photomask is not particularly limited, and a pattern corresponding to the target application is used. As a light source for exposure, a light source that generates light with a wavelength of 250 to 450 nm is preferable. For example, the light below 350 nm can be cut off with a filter that cuts off the wavelength range, or the light around 436 nm, 408 nm, and 365 nm can be selectively processed with a bandpass filter that extracts these wavelength ranges extract. Specifically, a mercury lamp, a light emitting diode, a metal halide lamp, a halogen lamp, etc. are mentioned. In order to uniformly irradiate the entire exposure surface with parallel light, or to accurately position the mask and the substrate, it is preferable to use a reduction projection exposure device such as a mask alignment exposure machine and a stepper exposure machine or an adjacent exposure device.

藉由使曝光後之組合物層接觸顯影液進行顯影,而於基板上形成著色圖案。藉由顯影,組合物層之未曝光部溶解於顯影液而得以去除。作為顯影液,例如較佳為氫氧化鉀、碳酸氫鈉、碳酸鈉、氫氧化四甲基銨等鹼性化合物之水溶液。該等鹼性化合物之水溶液中之濃度較佳為0.01~10質量%,更佳為0.03~5質量%。進而,顯影液可包含界面活性劑。顯影方法可為覆液法、浸漬法及噴霧法等任一者。進而,可於顯影時將基板向任意角度傾斜。 較佳為顯影後進行水洗。 A colored pattern is formed on the substrate by contacting the exposed composition layer with a developing solution for development. By development, the unexposed portion of the composition layer is dissolved in a developing solution and removed. As a developing solution, for example, an aqueous solution of a basic compound such as potassium hydroxide, sodium bicarbonate, sodium carbonate, tetramethylammonium hydroxide is preferable. The concentration in the aqueous solution of these basic compounds is preferably from 0.01 to 10% by mass, more preferably from 0.03 to 5% by mass. Furthermore, the developer may contain a surfactant. The developing method may be any one of a liquid covering method, a dipping method, a spraying method, and the like. Furthermore, the substrate can be tilted at any angle during development. It is preferable to perform water washing after image development.

進而,較佳為對所獲得之著色圖案進行後烘烤。後烘烤溫度較佳為80~250℃,更佳為100~245℃。後烘烤時間較佳為1~120分鐘,更佳為2~30分鐘。Furthermore, it is preferable to post-bak the obtained colored pattern.
