Abstract

A liquid crystal display includes: a first substrate and a second substrate arranged to face each other; a liquid crystal layer provided between the first substrate and the second substrate; first and second color filters of different colors, which are provided on the first substrate and arrayed in a first direction; and a first spacer provided between the first substrate and the second substrate and configured to adjust thickness of the liquid crystal layer. Each of the first and second color filters includes a first portion extending in a second direction intersecting with the first direction, and a second portion connected to the first portion and projected in the first direction. The first spacer is provided on the second portion.

Claims (62)

1. A liquid crystal display comprising:

a first substrate and a second substrate arranged to face each other;

a liquid crystal layer provided between the first substrate and the second substrate;

first and second color filters of different colors, which are provided on the first substrate and arrayed in a first direction; and

a first spacer provided between the first substrate and the second substrate, to adjust thickness of the liquid crystal layer,

wherein

each of the first and second color filters includes

a first portion extending in a second direction intersecting with the first direction, and

a second portion connected to the first portion and projected in the first direction,

an end of the first color filter and an end of the second color filter overlap to form an overlapping portion, and

the first spacer is provided on a portion of the second portion other than the overlapping portion.

2. The liquid crystal display according to claim 1 , wherein the second portion includes a convex portion projected in the first direction from a first side face of the first portion and a concave portion depressed in the first direction from a second side face of the first portion.

3. The liquid crystal display according to claim 1 , wherein a width of the second portion equal to a width of the first portion.

4. The liquid crystal display according to claim 1 , wherein the first spacer is arranged at an end of the second portion in the first direction.

5. The liquid crystal display according to claim 1 , wherein the first spacer is arranged at a boundary between adjacent pixels of the liquid crystal display.

6. The liquid crystal display according to claim 1 , wherein each of the first and second filters is corrugated.

7. The liquid crystal display according to claim 1 , further comprising:

a switching element provided on the second substrate,

wherein the first spacer is arranged in an area other than an area where the switching element is provided.

8. The liquid crystal display according to claim 1 , further comprising:

a light-shielding film provided between the first substrate and the first and second color filters and defining an opening area of a pixel of the liquid crystal display,

wherein the first spacer is arranged above the light-shielding film.

9. The liquid crystal display according to claim 1 , further comprising:

a second spacer which is lower than the first spacer,

wherein

the first color filter includes a plurality of first portions including the first portion and a plurality of second portions including the second portion, in which the plurality of first portions and the plurality of second portions repetitively alternate, and

the second spacer is provided on one of the plurality of second portions.

10. A liquid crystal display comprising:

a first substrate and a second substrate arranged to face each other;

a liquid crystal layer provided between the first substrate and the second substrate;

first and second color filters of different colors, which are provided on the first substrate and arrayed in a first direction; and

a first spacer provided between the first substrate and the second substrate, to adjust thickness of the liquid crystal layer,

wherein

the first color filter includes

a first portion extending in a second direction intersecting with the first direction, and

a second portion connected to the first portion and being wider than the first portion,

the second color filter includes

a third portion extending in the second direction, and

a fourth portion connected to the third portion and being narrower than the third portion, and

the first spacer is provided on the second portion.

11. The liquid crystal display according to claim 10 , wherein

the second portion includes a first convex portion projected in the first direction from a first side face of the first portion and a second convex projected in the first direction from a second side face of the first portion, and

the fourth portion includes a first concave portion depressed in the first direction from a first side face of the third portion and a second concave portion depressed in the first direction from a second side face of the third portion.

12. The liquid crystal display according to claim 10 , wherein the first spacer is arranged at an end of the second portion in the first direction.

13. The liquid crystal display according to claim 10 , wherein the first spacer is arranged at a boundary between adjacent pixels of the liquid crystal display.

14. The liquid crystal display according to claim 10 , wherein each of side faces of the first color filter is corrugated.

15. The liquid crystal display according to claim 10 , further comprising:

a switching element provided on the second substrate,

wherein the first spacer is arranged in an area other than an area where the switching element is provided.

16. The liquid crystal display according to claim 10 , further comprising:

a light-shielding film provided between the first substrate and the first and second color filters and defining an opening area of a pixel of the liquid crystal display,

wherein the first spacer is arranged above the light-shielding film.

17. The liquid crystal display according to claim 10 , further comprising:

a second spacer which is lower than the first spacer,

wherein

the first color filter includes a plurality of first portions and a plurality of second portions which repetitively alternate,

the second spacer is provided on one of the second portions.

18. The liquid crystal display according to claim 10 , wherein an end of the first color filter and an end of the second color filter overlap to form an overlapping portion, and

the first spacer is provided on a portion of the second portion other than the overlapping portion.

19. The liquid crystal display according to claim 10 , further comprising:

a second spacer provided on the second portion,

wherein the first spacer and the second spacer are arranged at both ends of the second portion in the first direction.
