  • Method of manufacturing color filter including exposing planarizing layer through openings in a medium layer
    Patent number: 5053298
    Abstract: A color filter and manufacturing method thereof are provided which can improve the optical transmittance and diminish the dispersion phenomena due to the diffraction and reflectance of incident light. The color filter has at least two mutually different filtering characteristics respectively corresponding to the plural pixels placed in a matrix on the background substrate. The color filter includes a planarizing layer, a color filter pattern, a coloring layer and a protective layer. The method for manufacturing the color filter involves forming a planarizing layer, a color filter pattern, and a protective layer.
