Abstract
A display screen having a color filter including a black matrix formed on a substrate of the display screen. A number of color filter layers, each formed in holes of the matrix, provide filtering of light components corresponding to the color of the filter layer. Also provided is one other color filter layer of a final color. This other color filter is also formed on the matrix and formed in another one of the other holes. Consequently, the other color filter layer can be formed without the need of exposing an associated resist layer, thereby simplifying the color filter manufacturing process.
