Abstract
A method for manufacturing a color filter array having hybrid color filters includes providing a high-grade photoresist and a low-grade photoresist, forming a plurality of first color filters on a substrate, and forming a plurality of second color filters and a plurality of third color filters on the substrate. The first color filters include the high-grade photoresist, and the second color filters and the third color filters include the low-grade photoresist. The high-grade photoresist of the first color filters includes a first amount of large size pigments in one unit area and the low-grade photoresists of the second color filters and the third color filters include a second amount of large size pigments in one unit area. A ratio of the second amount to the first amount is equal to or larger than 1.
