画素毎に染色する方法が一般的である。2 /+-> Conventional technology The conventional method for manufacturing color filters involves imparting photosensitivity to denatured proteins such as gelatin and casein, or synthetic dyeing resins, creating pixel patterns, and then dyeing them. A common method is to dye each pixel using a resist on the coated dyeable resin.

施されている。In order to obtain an image with good contrast, it is necessary to form a black matrix around each pixel of R2O and H. The black matrix can be obtained by mixing dyes of various colors or dyeing with black dye, by printing with black ink containing carbon powder, or by vapor depositing metals such as chromium. has been done.
発明が解決しようとする問題点

ので相当カーボン粉末の含有量を増やさねばならない。Metal vapor deposition such as aluminum vapor deposition has the disadvantage of being extremely expensive. In the case of black ink containing carbon powder by the printing method, the thickness of the printed area must be several μm, so the content of carbon powder must be increased accordingly.
ところがカーボン粉末の含有量を増やすとインキとして

せなかった。In an ink containing only carbon without blending titanium oxide powder, even if the carbon powder content was increased by 255 parts by weight, the light transmittance was as high as 7 to 8 percent, making it impractical. Further, when the carbon powder content was increased to 300 parts by weight or more, the ink became viscous and good printability was not found.
