8. The color filter substrate of claim 1 , wherein the first substrate comprises a third sub-pixel region corresponding to another non-white color region and adjacent to the second sub-pixel region, and

wherein the light-blocking pattern further comprises another disconnected portion between the second sub-pixel region and the third sub-pixel region.

9. A liquid crystal display (LCD) comprising:

a color filter substrate;

an opposite substrate which is opposite the color filter substrate; and

a liquid crystal layer disposed between the color filter substrate and the opposite substrate,

wherein the color filter substrate comprises:

a first substrate comprising a first sub-pixel region corresponding to a non-white color region and a second sub-pixel region corresponding to a white color region adjacent to the first sub-pixel region;

a light-blocking pattern disposed on the first substrate, the light-blocking pattern including a first opening corresponding to the first sub-pixel region, a second opening corresponding to the second sub-pixel region, and a sub-pixel boundary portion extending around the entire periphery of the first sub-pixel region except for a disconnected portion between the first sub-pixel region and the second sub-pixel region such that the first and second openings are coupled to each other via the disconnected portion of the sub-pixel boundary portion;

a first color filter having a first color and disposed in the first sub-pixel region; and

a transparent layer disposed in the second sub-pixel region and on the first color filter.

10. The LCD of claim 9 , wherein the first color is one of red, green, and blue.

12. The LCD of claim 9 , wherein the second opening is filled with the transparent layer.

13. The LCD of claim 9 , wherein the disconnected portion is filled with the transparent layer.

14. A method of manufacturing a color filter substrate, the method comprising:

forming a light-blocking pattern on a first substrate, the light-blocking pattern including a first opening corresponding to a first sub-pixel region, a second opening corresponding to a second sub-pixel region, and a sub-pixel boundary portion extending around the entire periphery of the first sub-pixel region except for a disconnected portion between the first sub-pixel region and the second sub-pixel region such that the first and second openings are coupled to each other via the disconnected portion of the sub-pixel boundary portion, wherein the first sub-pixel region corresponds to a non-white color region and the second sub-pixel region corresponds to a white color region adjacent to the first sub-pixel region;

forming a first color filter in the first sub-pixel region, the first color filter having a first color; and

forming a transparent layer in the second sub-pixel region and on the first color filter.

15. The method of claim 14 , wherein the transparent layer is electrically insulative.

16. The method of claim 14 , wherein the first sub-pixel region comprises at least one selected from red, green, and blue sub-pixel regions.

17. The method of claim 14 , wherein, in the forming of the transparent layer, a portion of the transparent layer fills at least a portion of the disconnected portion.

18. The method of claim 14 , wherein, in the forming of the transparent layer, a portion of the transparent layer fills the second opening.

19. The method of claim 14 , wherein the second sub-pixel region is surrounded by red, green, and blue sub-pixel regions.
