Abstract

A liquid crystal display includes first and second substrates. The first substrate has a first insulating substrate, and a pixel electrode formed on the first insulating substrate with a first opening pattern. The second substrate has a second insulating substrate, and a common electrode formed on the second insulating substrate with a second opening pattern. The first and the second opening patterns proceed parallel to each other while being arranged in an alternate manner. A liquid crystal material is injected between the first and the second substrates. A spacer is positioned at an end of the second opening pattern to maintain the distance between the first and the second substrates.

Claims (38)

1. A liquid crystal display, comprising:

a first substrate and a second substrate;

a liquid crystal layer being sandwiched between the first and second substrates;

a gate line and a data line provided on the first substrate;

a plurality of pixel electrodes provided on the first substrate;

a plurality of domain dividers disposed on the second substrate, the domain dividers comprising bodies that are arranged obliquely with respect to the gate line and branches extending from the bodies in a first direction along edges of the pixel electrodes; and

a first spacer arranged on the gate line and extending in a second direction from where one of the bodies meets one of the edges of the pixel electrodes, the second direction being opposite the first direction.

2. The liquid crystal display as claimed in claim 1 , further comprising:

a plurality of openings provided in the pixel electrodes; and

the openings and the bodies are arranged alternately.

3. The liquid crystal display as claimed in claim 2 , wherein the domain dividers further comprise a trunk extended from one of the bodies and disposed on the second substrate, the trunk and one of the openings being arranged collinearly.

4. The liquid crystal display as claimed in claim 3 , further comprising a second spacer formed at a location adjacent to the trunk.

5. The liquid crystal display as claimed in claim 3 , further comprising a first storage capacitor line provided on the first substrate and disposed at one of the edges of the pixel electrodes or at a center portion of one of the pixel electrodes.

6. The liquid crystal display as claimed in claim 5 , further comprising a second storage capacitor line provided on the first substrate, and extended from the first storage capacitor line and along an extending direction of the data line.

7. The liquid crystal display as claimed in claim 1 , wherein each of the bodies is linear shape or chevron shape, and wherein the domain dividers further comprise a trunk extended from the chevron shape body.

8. The liquid crystal display as claimed in claim 7 , further comprising a first storage capacitor line provided on the first substrate and disposed at one of the edges of the pixel electrodes or at a center portion of one of the pixel electrodes.

9. The liquid crystal display as claimed in claim 7 , further comprising a second spacer formed at a location adjacent to the trunk.

10. The liquid crystal display as claimed in claim 8 , further comprising a second storage capacitor line provided on the first substrate, and extended from the first storage capacitor line and along an extending direction of the data line.

11. The liquid crystal display as claimed in claim 1 , wherein the domain dividers are protrusions or openings.

12. A liquid crystal display, comprising:

a first substrate and a second substrate;

a liquid crystal layer being sandwiched between the first and second substrates;

a gate line and a data line provided on the first substrate;

a pixel electrode formed on the first substrate;

a plurality of domain dividers disposed on the second substrate, the domain dividers comprising bodies arranged obliquely with respect to the gate line, branches extending from the bodies along edges of the pixel electrode, and a trunk extended from one of the bodies;

a first spacer arranged on the gate line;

a second spacer arranged at a location adjacent to the trunk.

13. The liquid crystal display as claimed in claim 12 , wherein one of the branches is extending in a first direction and the first spacer is extending in a second direction from where one of the bodies meets one of the edges of the pixel electrode, the second direction being opposite the first direction.

14. The liquid crystal display as claimed in claim 12 , further comprising:

a plurality of openings provided in the pixel electrode; and

the openings and the bodies are arranged alternately,

wherein the trunk and one of the openings being arranged collinearly.

15. The liquid crystal display as claimed in claim 14 , further comprising a first storage capacitor line provided on the first substrate and disposed at one of the edges of the pixel electrode or at a center portion of the pixel electrode.

16. The liquid crystal display as claimed in claim 15 , further comprising a second storage capacitor line provided on the first substrate, and extended from the first storage capacitor line and along an extending direction of the data line.

17. The liquid crystal display as claimed in claim 12 , wherein each of the bodies is linear shape or chevron shape and wherein the trunk is extended from the chevron shape body of the bodies.

18. The liquid crystal display as claimed in claim 12 , further comprising a first storage capacitor line provided on the first substrate and disposed at one of the edges of the pixel electrode or at a center portion of the pixel electrode.

19. The liquid crystal display as claimed in claim 18 , further comprising a second storage capacitor line provided on the first substrate, and extended from the first storage capacitor line and along an extending direction of the data line.

20. The liquid crystal display as claimed in claim 12 , wherein the domain dividers are protrusions or openings.
