Color filter and manufacturing method thereof
A method for manufacturing a color filter is provided. The method includes following steps. A substrate is provided. A first filter layer is formed on a first part of a first region and a first part of a second region of the substrate. A second filter layer is formed on a second part of the second region. A third filter layer is formed on a second part of the first region and a third part of the second region. When a white beam is projected on the color filter, the first region and the second region reflect a plurality of color beams. A color filter manufactured through the method is also provided.
1. A manufacturing method of a color filter, comprising:
providing a substrate, wherein the substrate has a first region and a second region;
forming a first filter layer on a first part of the first region and a first part of the second region;
forming a second filter layer on a second part of the second region, wherein the step of forming the second filter layer comprises forming a plurality of first multi-film filter units on where the first part and the second part of the second region overlap each other, and when a white beam is projected on the first multi-film filter units, the first multi-film filter units reflect a third color beam; and
forming a third filter layer on a second part of the first region and a third part of the second region;
wherein when the white beam is projected on the color filter, the first region and the second region reflect a plurality of color beams.
2. The manufacturing method according to claim 1 , wherein the first region comprises a plurality of single-film filter units, and the second region comprises the plurality of multi-film filter units.
3. The manufacturing method according to claim 1 , wherein the step of forming the first filter layer comprises:
forming a plurality of first single-film filter units on the first part of the first region, wherein when the white beam is projected on the first single-film filter units, the first single-film filter units reflect a first color beam.
4. The manufacturing method according to claim 1 , wherein the step of forming the third filter layer comprises:
forming a plurality of second single-film filter units on the second part of the first region, wherein when the white beam is projected on the second single-film filter units, the second single-film filter units reflect a second color beam.
5. The manufacturing method according to claim 1 , wherein the step of forming the third filter layer comprises:
forming a plurality of second multi-film filter units on where the second part and the third part of the second region overlap each other, wherein when the white beam is projected on the second multi-film filter units, the second multi-film filter units reflect a fourth color beam.
6. The manufacturing method according to claim 1 , wherein the step of forming the third filter layer comprises:
forming a plurality of third multi-film filter units on where the first part and the third part of the second region overlap each other, wherein when the white beam is projected on the third multi-film filter units, the third multi-film filter units reflect a fifth color beam.
7. The manufacturing method according to claim 1 , wherein when the white beam is projected on the substrate, the first region reflects a yellow beam and a cyan beam.
8. The manufacturing method according to claim 1 , wherein when the white beam is projected on the substrate, the second region reflects a red beam, a blue beam, and a green beam.
9. The manufacturing method according to claim 1 , wherein materials of the first filter layer, the second filter layer, and the third filter layer are color resists.
