Abstract

According to one embodiment, a liquid crystal display apparatus includes a first substrate including a first electrode and an insulating layer arranged so as to cover an edge of the first electrode, a second substrate including a second electrode facing the first electrode and a second slit from which the second electrode is removed, and a liquid crystal layer interposed between the first substrate and the second substrate. The first electrode includes a plurality of first slits extending inwardly from the edge of the first electrode. The insulating layer and the plurality of first slits are arranged such that a position of an end of the insulating layer and a position of a tip to which the first slit extends are apart from each other in a region between the edge of the first electrode and the second slit in a direction in which the first slit extends.

Claims (20)

1. A liquid crystal display apparatus comprising:

a first substrate including a first electrode and an insulating layer arranged so as to cover an edge of the first electrode;

a second substrate including a second electrode facing the first electrode and a second slit from which the second electrode is removed and extending in a first direction; and

a liquid crystal layer interposed between the first substrate and the second substrate, the liquid crystal layer being formed of a liquid crystal material having negative dielectric constant anisotropy, wherein

the first electrode includes a plurality of first slits extending inwardly in a second direction crossing the first direction from the edge of the first electrode, and

the insulating layer and said plurality of first slits are arranged such that a position of an end of the insulating layer and a position of a tip to which the first slit extends are apart from each other in a region between the edge of the first electrode and the second slit in a direction in which the first slit extends.

2. The liquid crystal display apparatus according to claim 1 , wherein the end of the insulating layer is positioned closer to the second slit than the tip of said plurality of first slits, in the direction in which the first slit extends.

3. The liquid crystal display apparatus according to claim 2 , wherein a distance from the edge of the first electrode to the tip of said plurality of first slits, a distance from the tip of the first slit to the end of the insulating layer, and a distance from the end of the insulating layer to the end of the second slit are equal, in the direction in which the first slit extends.

4. The liquid crystal display apparatus according to claim 1 , wherein the tip of said plurality of first slits is positioned closer to the second slit than the end of the insulating layer in the direction in which the first slit extends.

5. The liquid crystal display apparatus according to claim 4 , wherein a distance from the edge of the first electrode to the end of the insulating layer, a distance from the end of the insulating layer to the tip of the first slit, and a distance from the tip of the first slit to the end of the second slit are equal.

6. A liquid crystal display apparatus, comprising:

a first substrate including a first electrode and an insulating layer arranged so as to cover an edge of the first electrode;

a second substrate including a second electrode facing the first electrode and a rib arranged on the second electrode and extending in a first direction; and

a liquid crystal layer interposed between the first substrate and the second substrate, the liquid crystal layer being formed of a liquid crystal material having negative dielectric constant anisotropy, wherein

the first electrode includes a plurality of slits extending inwardly in a second direction crossing the first direction from the edge of the first electrode, and

the insulating layer and said plurality of slits are arranged such that a position of an end of the insulating layer and a position of a tip to which the slit extends are apart from each other in a region between the edge of the first electrode and a position in which the rib is arranged in a direction in which the slit extends.

7. The liquid crystal display apparatus according to claim 6 , wherein the end of the insulating layer is positioned closer to the rib than the tip of the slit, in the direction in which the slit extends.

8. The liquid crystal display apparatus according to claim 7 , wherein a distance from the edge of the first electrode to the tip of the slit, a distance from the tip of the slit to the end of the insulating layer, and a distance from the end of the insulating layer to the end of the rib are equal, in the direction in which the first slit extends.

9. The liquid crystal display apparatus according to claim 6 , wherein the tip of the slit is positioned closer to the rib than the end of the insulating layer in the direction in which the slit extends.

10. The liquid crystal display apparatus according to claim 9 , wherein a distance from the edge of the first electrode to the end of the insulating layer, a distance from the end of the insulating layer to the tip of the slit, and a distance from the tip of the slit to the end of the rib are equal, in the direction in which the slit extends.
