Abstract

A color filter pattern including a plurality of color filters arranged in a pattern and the manufacturing method thereof are provided. By performing at least one two-stage exposure process to a color filter layer, the plurality of color filters are formed with a sharp profile.

Claims (17)

1. A green color filter pattern, comprising:

a plurality of green color filters on a substrate, wherein each of the plurality of green color filters has a substantially vertical sidewall and a slant jut located at the bottom of the sidewall and protruding outwards from the sidewall, and a height of the jut is less than fifth of a height of each of the plurality of green color filters.

2. The green color filter pattern of claim 1 , wherein the height of the jut is less than tenth of the height of each of the plurality of green color filters.

3. The green color filter pattern of claim 1 , wherein an angle between a slat surface of the jut and the substrate is less than 30 degrees.

4. The green color filter pattern of claim 1 , wherein the plurality of green color filters is arranged in a checker pattern.

5. A color filter pattern, comprising:

a plurality of green color filters on a substrate, wherein each of the plurality of green color filters has a substantially vertical sidewall and a slant jut located at the bottom of the sidewall and protruding outwards from the sidewall, wherein a height of the jut is less than a height of each of the plurality of green color filters;

a plurality of blue color filters, disposed on the substrate and located beside the plurality of green color filters; and

a plurality of red color filters, disposed on the substrate and located beside the plurality of green color filters and beside the plurality of blue color filters.

6. The color filter pattern of claim 5 , wherein the height of the jut is less than fifth of the height of each of the plurality of green color filters.

7. The color filter pattern of claim 5 , wherein the height of the jut is less than tenth of the height of each of the plurality of green color filters.

8. The color filter pattern of claim 5 , wherein an angle sandwiched between a slant surface of the slant jut and the substrate is less than 30 degrees.

9. The color filter pattern of claim 5 , wherein the plurality of green color filters is arranged in a checker pattern.

10. The color filter pattern of claim 9 , wherein the plurality of blue color filters is arranged in a tartan check pattern and arranged among the checker pattern of the plurality of the green color filters, wherein at least one side of each of the plurality of blue color filters is in contact with at least one side of each of the plurality of green color filters.

11. The color filter pattern of claim 10 , wherein the plurality of red color filters is arranged in a tartan check pattern and arranged among the tartan check pattern of the plurality of the blue color filters, wherein at least three sides of each of the plurality of red color filters are in contact with at least three sides of each of the plurality of blue color filters.

12. The color filter pattern of claim 9 , wherein the plurality of blue red filters is arranged in a tartan check pattern and arranged among the checker pattern of the plurality of the green color filters, wherein at least one side of each of the plurality of red color filters is in contact with at least one side of each of the plurality of green color filters.

13. The color filter pattern of claim 12 , wherein the plurality of blue color filters is arranged in a tartan check pattern and arranged among the tartan check pattern of the plurality of the red color filters, wherein at least three sides of each of the plurality of blue color filters are in contact with at least three sides of each of the plurality of red color filters.
