    • PURPOSE: A colored composition for a color filter and a display using the color filter formed of the colored composition are provided to improve contrast, color purity, transmittance of blue color and productivity for the color filter, and realize high contrast, high color purity and high transmittance of blue color in the display by using polyamicacid of which light transmittance decreases by 2% or less in the visible region as a base polymer, in the colored composition for color filter comprising the base polymer, coloring agent and solvent. CONSTITUTION: The first substrate(SUB1) has a plurality of scanning lines(GL), a plurality of signal lines(DL), and a plurality of color pixels formed at the intersections of the scanning lines and the signal lines. The second substrate(SUB2) has color filters(FIL) of two or more colors located to face the pixels, respectively. A liquid crystal layer(LC) is enclosed in a gap formed by sticking the first substrate and the second substrate to each other. Each of the color filters is formed of a colored composition for color filter comprising a base polymer containing polyamicacid of which light transmittance decreases by 2% or less in the visible region(wavelength: 400 nm to 800 nm), coloring agent and solvent.
    • 目的:提供用于滤色器的彩色组合物和使用由着色组合物形成的滤色器的显示器,以提高对比度,色纯度,蓝色透光度和滤色片的生产率,并实现高对比度,高色纯度和 在基色聚合物,着色剂和溶剂的彩色滤色器的着色组合物中,通过使用在作为基础聚合物的可见光区域的光线透过率降低2%以下的聚酰胺酸,显示器中蓝色的透光率高。 构成:第一衬底(SUB1)具有多个扫描线(GL),多个信号线(DL)和形成在扫描线和信号线的交点处的多个彩色像素。 第二基板(SUB2)分别具有位于像素的两个或多个颜色的滤色器(FIL)。 液晶层(LC)被封闭在通过将第一基板和第二基板彼此粘合而形成的间隙中。 每个滤色器由用于滤色器的着色组合物形成,包括含有聚酰胺酸的基础聚合物,其中可见光区域(波长:400nm至800nm)的光线透射率降低2%以下,着色剂和溶剂。
