Method for producing color filter. |
摘要 |
<p>A method for producing a color filter involves the steps of: (A) forming a photosensitive coating film on a transparent electrically conductive layer formed on a surface of a transparent substrate, and exposing the photosensitive coating film through a mask having patterns of at least three different degrees of light transmittances; (B) developing and removing a photosensitive coating film portion registering with one of the patterns of smallest and largest degrees of light transmittances for exposing the transparent electrically conductive layer, and electrodepositing a colored coating on the exposed transparent electrically conductive layer for forming a colored layer thereon; and (C) repeating the step (B) for the respective patterns of defferent degrees of light transmittances in sequence of difference in transmittances for producing different colored layers, respectively. <IMAGE></p> |
