    • A color filter having a plurality of color layers on the surface of a transparent substrate, at least one of the color layers having a defect of layer unflatness, which is produced due to unevenness caused by contamination with foreign matters is repaired by a simple, industrially advantageous method. The method includes the steps of
      (1) eliminating a defective part of the color layers to produce a blank there, (2) filling the blank with a negative type photosensitive composition containing a colorant, and (3) exposing the photosensitive composition to light emitted from the side opposite to the color layer-carrying surface of the substrate, followed by development to eliminate the photosensitive composition unexposed to light. The color filter repaired is used to fablicate multi-color display devices which are by no means inferior in display qualities to those fablicated using a color filter having no defect originally.
    • 在透明基板的表面具有多个着色层的彩色滤光片中,由于异物污染引起的凹凸而产生的具有层不平整性的缺陷的至少一个着色层通过简单的工业 有利的方法。 该方法包括以下步骤:(1)消除有色层的有缺陷部分以在那里生成坯件;(2)用包含着色剂的负型光敏组合物填充坯件;以及(3)将光敏组合物暴露于发射的光 从与衬底的着色层承载表面相对的一侧开始,随后显影以除去未曝光的光敏组合物。 修复的彩色滤光片被用于制造多色显示装置,这些显示装置在显示质量上不逊于使用原来没有缺陷的彩色滤光片制造的显示装置。
