5. The display device as claimed in claim 1 , further comprising:

a sub-spacer disposed over the first substrate and disposed in the pixel-displaying region, wherein a region corresponding to the sub-spacer does not comprise the enlarged portion.

6. The display device as claimed in claim 5 , further comprising:

a first alignment layer disposed over the first substrate; and

a second alignment layer disposed over the second substrate,

wherein the first alignment layer is aligned by a photo-alignment process.

7. The display device as claimed in claim 2 , further comprising:

a first alignment layer disposed over the first substrate; and

a second alignment layer disposed over the second substrate,

wherein the second alignment layer comprises a rough region corresponding to the main spacer.

8. The display device as claimed in claim 7 , wherein a distance between a top surface of the main spacer to an edge of the rough region ranges from about 0 μm to 12 μm.

9. The display device as claimed in claim 7 , wherein a roughness of the rough region of the second alignment layer is different from a roughness of other region of the second alignment layer.

10. The display device as claimed in claim 1 , wherein in the sub-pixel region, the amount of the enlarged portion between two of the adjacent sub-pixel columns is one or less, and the amount of the enlarged portion between two of the adjacent sub-pixel rows is one or less.

11. The display device as claimed in claim 1 , wherein one of the enlarged portions is spaced apart from another most adjacent enlarged portion by three sub-pixel columns.

12. The display device as claimed in claim 1 , further comprising at least one main spacer, wherein all region corresponding to the at least one main spacer has the enlarged portion.

13. The display device as claimed in claim 12 , further comprising at least one sub-spacer, wherein a region corresponding to the at least one sub-spacer has the enlarged portion.

14. The display device as claimed in claim 12 , wherein a portion of the region corresponding to the enlarged portions does not have the main spacer and the sub-spacer.

15. The display device as claimed in claim 1 , further comprising a plurality of sub-spacers, wherein each pixel comprises three sub-pixels, and a ratio of an amount of the plurality of the sub-spacers to an amount of the sub-pixels is 1:3.
