Color filter and color display device using same

摘要

A color filter includes a substrate and a plurality of pixel units. The substrate defines a plurality of pixel areas. Each pixel area has a plurality of first sub-pixel areas, and each first sub-pixel area has a first area and a second area. The pixel units are formed on the substrate corresponding to the pixel areas. Each pixel unit is disposed in a corresponding pixel area and includes a plurality of color subtractive filter films and a plurality of color additive filter films. The color subtractive filter films are disposed in the first areas of the first sub-pixel areas of the corresponding pixel area, and the color additive filter films are disposed in the second areas of the first sub-pixel areas of the corresponding pixel area. A color display device with the color filter is also disclosed.

主权项

1. A color filter comprising:
a substrate defining a plurality of pixel areas, each pixel area having a plurality of first sub-pixel areas, each first sub-pixel area having a first color area and a second color area, wherein said second color area is adjacent to and directly connected to the first color area, the first color area and the second color area being not overlapped with each other, and the first sub-pixel areas being not connected to each other; and a plurality of pixel units formed on the substrate corresponding to the pixel areas, each pixel unit disposed in a corresponding pixel area and comprising a plurality of color subtractive filter films and a plurality of color additive filter films, wherein the color subtractive filter films are disposed in said first color areas of corresponding said first sub pixel area, the color additive filter films are disposed in said second color areas of corresponding said first sub pixel area, the color subtractive filter films comprise a red filter film, a green filter film and a blue filter film, and the color additive filter films comprise a magenta filter film, a cyan filter film and a yellow filter film.
