the rough mark on the color filter substrate is in a shape correspondingly selected from the group consisting of a square, a rectangle, a ellipse and a circle, and

the size of the rough mark on the color filter is smaller than that of a inner ring of the rough mark on the array substrate.

3. The liquid crystal display as claimed in claim 1 , wherein the fine mark on the array substrate comprises a fine mark in an X direction and a fine mark in a Y direction on a plane of the array substrate; and the fine mark on the color filter substrate comprises a fine mark in the X direction and a fine mark in the Y direction on a plane of the color filter substrate,

wherein the fine marks in the X direction and the Y direction on the array substrate comprise at least two fine mark signs arranged parallel to each other; and the fine marks in the X direction and the Y direction on the color filter substrate also comprise at least two fine mark signs arranged parallel to each other;

a shape and a size of a gap between the fine mark signs of each fine mark on the array substrate corresponds to a shape and a size of the fine mark signs of each fine mark on the color filter substrate, respectively; and

a shape and a size of a gap between the fine mark signs of each fine mark on the color filter substrate corresponds to a shape and a size of each fine mark signs of the fine mark on the array substrate, respectively.

4. The liquid crystal display as claimed in claim 3 , wherein

the fine mark signs of each fine mark on the array substrate have a shape selected from the group consisting of a rectangle shape, a reverse L shape, a triangle shape and a trapezoid shape.

5. The liquid crystal display as claimed in claim 3 , wherein

among the fine mark signs of each fine mark on the array substrate, at least one fine mark sign is a preceding mark sign, and the preceding mark sign is longer than the rest fine mark signs.

6. The liquid crystal display as claimed in claim 5 , wherein

the rest fine mark signs of each fine mark on the array substrate except the preceding mark sign have an equal length.

7. The liquid crystal display as claimed in claim 3 , wherein

among the fine mark signs of each fine mark on the color filter substrate, at least one fine mark sign is a preceding mark sign, and the preceding mark sign is longer than the rest fine mark signs.

8. The liquid crystal display as claimed in claim 7 , wherein

the rest fine mark signs of each fine mark on the color filter substrate except the preceding mark sign have an equal length.

9. The liquid crystal display as claimed in claim 5 , wherein

among the fine mark signs of each fine mark on the color filter substrate, at least one fine mark sign is a preceding mark sign, and the preceding mark sign is longer than the rest fine mark signs.

10. The liquid crystal display as claimed in claim 9 , wherein

the rest fine mark signs of each fine mark on the color filter substrate except the preceding mark sign have an equal length.

11. The liquid crystal display as claimed in claim 3 , wherein

intervals between the mark signs of each fine mark on the array substrate are equal or unequal to each other.

12. The liquid crystal display as claimed in claim 3 , wherein

widths of the mark signs of each fine mark on the array substrate are equal or unequal to each other.

13. The liquid crystal display as claimed in claim 3 , wherein

intervals between the mark signs of each fine mark on the array substrate is equal or unequal to widths of the mark signs.

14. The liquid crystal display as claimed in claim 3 , wherein widths of the fine mark signs of each fine mark are 0.3 μm˜1.0 mm.

15. A substrate, comprising a combination type mark disposed on the substrate, wherein the combination type mark comprises a rough mark and a fine mark that is located around the rough mark, and the fine mark signs of each fine mark on the substrate are in a shape selected from the group consisting of a reverse L shape, a triangle shape and a trapezoid shape.

16. The substrate as claimed in claim 15 , wherein the fine mark comprises:

a fine mark in an X direction and a fine mark in a Y direction on a plane of the substrate, and

the fine mark comprise at least two fine mark signs arranged parallel to each other.

17. The substrate as claimed in claim 16 , wherein among the fine mark signs of each fine mark on the substrate, at least one fine mark sign is a preceding mark sign, and the preceding mark sign is longer than the rest mark signs.

18. The substrate as claimed in claim 17 , wherein

the rest fine mark signs of each fine mark on the substrate except the preceding mark sign have an equal length.
