Abstract
A color filter and a method for manufacturing the same are provided. The color filter includes a polarizer matrix (202), which is patterned in accordance with the pixel arrangement of a liquid crystal display device. The polarizer matrix (202) is made of a thin crystal film material, which may linearly polarize incident light along one direction. By incorporating with a polarizer film (206), the polarizer matrix (202) becomes an effective black matrix. A thinner black matrix may thus be produced, and the manufacturing processes of the color filter are simplified.

A color filter for use in a liquid crystal display device, comprising:
- a substrate having two surfaces;
- a polarizer matrix having a first polarization direction formed on one surface of said substrate defining a plurality of openings;
- and
- a color filter layer formed on said substrate in the openings of said polarizer matrix.
A method for manufacturing a color filter, which comprises the steps of:
- (a) providing a substrate having a first surface and a second surface;
- (b) forming a polarizer matrix on the first surface of the substrate and defining a plurality of openings;
- and
- (c) curing the substrate, on which a polarizer matrix has been formed, in an oven.
A color filter for use in a liquid crystal display device, comprising:
- a substrate having opposite first and second surfaces;
- polarizer areas having a first polarization direction and formed on the first surface of said substrate and defining a plurality of openings therebetween;
- a color filter layer formed on the first surface of said substrate at least in the openings of said polarizer areas.
