Liquid crystal display apparatus having color filter with color connection on black matrix and method of manufacturing the same

1. A liquid crystal display (LCD) apparatus comprising:

a backlight;

a first electrode and a second electrode disposed over the backlight, wherein the first and second electrodes extend in a plane along a first direction;

a liquid crystal layer disposed between the first electrode and the second electrode; and

a color filter unit comprising a first color filter, a second color filter, and a third color filter, disposed over the second electrode, wherein the first, second and third color filters are respectively divided by a black matrix having a black matrix thickness when viewed in a second direction perpendicular to the first direction;

wherein the first color filter and the second color filter each comprises:

a plurality of display regions, each display region having a first length in a third direction perpendicular to the first direction and to the second direction, a first thickness in the second direction, and a first width in the first direction, and

a plurality of connection portions, each connection portion having a second length in the third direction, a second thickness in the second direction, and a second width in the first direction, each connection portion overlapping with the black matrix and connecting two adjacent display regions to each other,

wherein the first length is larger than the second length, and wherein the first width is larger than the second width, and

wherein the sum of the black matrix thickness and the second thickness is smaller than the first thickness.

2. The LCD apparatus of claim 1 , wherein the third color filter is formed to have a stripe shape.

3. The LCD apparatus of claim 1 , wherein the black matrix regions are formed on a peripheral portion of display regions.

4. The LCD apparatus of claim 1 , wherein each of the respective display regions of the first and second color filters corresponds to a sub-pixel for displaying a respective color.

5. A method of manufacturing an LCD apparatus, the method comprising:

using a backlight;

providing a first electrode and a second electrode over the backlight, wherein the first and second electrodes extend in a plane along a first direction;

providing a liquid crystal layer between the first electrode and the second electrode; and

forming a color filter unit comprising a first color filter, a second color filter, and a third color filter, over the second electrode, wherein the first, second and third color filters are respectively divided by a black matrix having a black matrix thickness when viewed in a second direction perpendicular to the first direction;

wherein the first color filter and the second color filter each comprises:

a plurality of display regions, each display region having a first length in a third direction perpendicular to the first direction and to the second direction, a first thickness in the second direction, and a first width in the first direction, and

a plurality of connection portions, each connection portion having a second length in the third direction, a second thickness in the second direction, and a second width in the first direction, each connection portion overlapping with the black matrix and connection two adjacent display regions to each other,

wherein the first length is larger than the second length, and wherein the first width is larger than the second width, and

wherein the sum of the black matrix thickness and the second thickness is smaller than the first thickness.

6. The method of claim 5 , wherein the forming of the color filter unit comprises forming the third color filter after forming the first color filter and the second color filter.

7. The method of claim 5 , wherein the forming of the color filter unit comprises forming the plurality of display regions and the plurality of connection portions simultaneously by using a half-tone mask when the first and second color filters are respectively formed.

8. The method of claim 5 , wherein the third color filter is formed in the shape of a stripe.

9. The method of claim 5 , wherein the black matrix regions are formed on a peripheral portion of display regions.

10. The method of claim 5 , wherein each of the plurality of respective display regions of the first and second color filters corresponds to a sub-pixel for displaying a respective color.
