Abstract

A liquid crystal display includes: a pair of substrates which are disposed so as to be opposite each other and have a liquid crystal layer interposed therebetween; an upper electrode configured to be included in one substrate of the pair of substrates, and be formed so as to have a plurality of slits therein; and a lower electrode configured to be included in the one substrate of the pair of substrates, and be formed on an insulating film covering the upper electrode so as to be partially overlapped with the upper electrode in plan view; wherein the lower electrode has at least one slit which is formed so as to be parallel with the plurality of slits formed in the upper electrode; and wherein the at least one slit formed in the lower electrode is formed so as to be overlapped with the upper electrode in plan view.

Claims (12)

1. A liquid crystal display panel, comprising:

A pair of substrates which are disposed so as to be opposite each other and have a liquid crystal layer interposed therebetween;

an upper electrode configured to be included in one substrate of the pair of substrates, and be formed so as to have a plurality of slits therein; and

a lower electrode configured to be included in the one substrate of the pair of substrates, and be formed on an insulating film covering the upper electrode so as to be partially overlapped with the upper electrode in plan view,

wherein the lower electrode has at least one slit which is formed so as to be parallel with the plurality of slits formed in the upper electrode, and

wherein the at least one slit formed in the lower electrode is located entirely below the upper electrode in plan view.

2. The liquid crystal display panel according to claim 1 , wherein the at least one slit formed in the lower electrode is formed so as to be of a width smaller than a width of each portion between two successive slits out of the plurality of slits formed in the upper electrode, and be entirely overlapped with the upper electrode in plan view.

3. The liquid crystal display panel according to the claim 1 , wherein the number of the at least one slit formed in the lower electrode is less than the number of the plurality of slits formed in the upper electrode.

4. The liquid crystal display panel according to claim 1 , wherein each of the at least one slit formed in the lower electrode is formed so as to be of a width larger than a width of each portion between two successive slits out of the plurality of slits formed in the upper electrode.

5. The liquid crystal display panel according to claim 1 , wherein the at least one slit formed in the lower electrode includes a plurality of slits, and

wherein each of the plurality of slits formed in the lower electrode is disposed below every second portion of the portions located between two successive slits out of the plurality of slits formed in the upper electrode.

6. The liquid crystal display panel according to claim 1 , wherein the lower electrode is formed on a inter-layer film which is formed in the one substrate of the pair of substrates.
