Abstract
A color filter is described, including a first color filter layer, a first light absorbing layer, a second color filter pattern and a second light absorbing pattern. The first color filter layer is disposed over a substrate. The first light absorbing layer is disposed between the substrate and the first color filter layer. The second color filter pattern covers a portion of the first color filter layer. The second light absorbing pattern is disposed between the second color filter pattern and the first color filter layer.
Claims20
A color filter, comprising:
- a first color filter layer over a substrate;
- a first light absorbing layer between the substrate and the first color filter layer, wherein the first light absorbing layer entirely covers the substrate;
- a second color filter pattern, covering a portion of the first color filter layer;
- and
- a second light absorbing pattern between the second color filter pattern and the first color filter layer, wherein the second color filter pattern reflects a portion of a wavelength range of a light beam and the second light absorbing pattern absorbs the other portion of the wavelength range of the light beam.
