Abstract

A liquid crystal display includes a first substrate, a first field generating electrode arranged on the first substrate and including first and second cutouts, and a second substrate facing the first substrate. A second field generating electrode is arranged on the second substrate and includes a third cutout, and a liquid crystal layer is interposed between the first and second field generating electrodes. A column spacer is interposed between the first and second substrates and is disposed in the first cutout region.

Claims (43)

1. A liquid crystal display, comprising:

a first substrate;

a first field generating electrode arranged on the first substrate, the first field generating electrode comprising a first cutout and a second cutout;

a second substrate facing the first substrate;

a thin film transistor arranged on the second substrate;

a second field generating electrode arranged on the second substrate and connected to the thin film transistor, the second field generating electrode comprising a third cutout;

a liquid crystal layer interposed between the first field generating electrode and the second field generating electrode; and

a column spacer arranged between the first substrate and the second substrate, the column spacer being arranged in a region substantially corresponding to the first cutout.

2. The liquid crystal display of claim 1 ,

wherein the second field generating electrode comprises a first oblique side, and the first cutout comprises a second oblique side that is parallel with the first oblique side, and

wherein a distance between a center axis of the column spacer and the first oblique side is less than a distance between the center axis of the column spacer and the second oblique side.

3. The liquid crystal display of claim 2 ,

wherein the column spacer decreases in width in a direction from the first substrate to the second substrate.

4. The liquid crystal display of claim 2 ,

wherein the first oblique side and the second oblique side are slanted at an angle of about 45° with respect to a gate line.

5. The liquid crystal display of claim 1 ,

wherein the second cutout and the third cutout are alternately disposed.

6. The liquid crystal display of claim 1 , further comprising a color filter arranged on the first substrate.

7. The liquid crystal display of claim 1 , wherein the first cutout is triangular shaped.

8. The liquid crystal display of claim 2 , wherein the first cutout is triangular shaped.

9. The liquid crystal display of claim 1 , wherein the column spacer is arranged entirely within the region corresponding to the first cutout.

10. A liquid crystal display, comprising:

a first substrate;

a first field generating electrode arranged on the first substrate, the first field generating electrode comprising a first cutout and a second cutout;

a second substrate facing the first substrate;

a second field generating electrode arranged on the second substrate, the second field generating electrode comprising a third cutout;

a storage electrode arranged on the second substrate, the storage electrode overlapping with the second field generating electrode to form a storage capacitor;

a liquid crystal layer interposed between the first field generating electrode and the second field generating electrode; and

a column spacer arranged between the first substrate and the second substrate, the column spacer being arranged in a region substantially corresponding to the first cutout.

11. The liquid crystal display of claim 10 ,

wherein the second field generating electrode comprises a first oblique side, and the first cutout comprises a second oblique side that is parallel with the first oblique side, and

wherein a distance between a center axis of the column spacer and the first oblique side is less than a distance between the center axis of the column spacer and the second oblique side.

12. The liquid crystal display of claim 11 ,

wherein the column spacer decreases in width in a direction from the first substrate to the second substrate.

13. The liquid crystal display of claim 11 ,

wherein the first oblique side and the second oblique side are slanted at an angle of about 45° with respect to a gate line.

14. The liquid crystal display of claim 10 ,

wherein the second cutout and the third cutout are alternately disposed.

15. The liquid crystal display of claim 10 , further comprising a color filter arranged on the first substrate.

16. The liquid crystal display of claim 10 , further comprising a thin film transistor arranged on the second substrate, wherein the thin film transistor is connected to the second field generating electrode.

17. The liquid crystal display of claim 10 , wherein the first cutout is triangular shaped.

18. The liquid crystal display of claim 11 , wherein the first cutout is triangular shaped.

19. The liquid crystal display of claim 10 , wherein the column spacer is arranged entirely within the region corresponding to the first cutout.
