Abstract

A liquid crystal display includes a first substrate including a first electrode and a second electrode formed thereon, a second substrate including a third electrode formed thereon, wherein the second substrate is spaced apart from the first substrate by a gap, and at least one cutout formed in the third electrode, wherein the at least one cutout is aligned with a space between the first and second electrodes.

Claims

1. A liquid crystal display comprising:

a plurality of data lines for transmitting data voltages formed on the first substrate; and

at least one cutout formed in the third electrode, wherein the at least one cutout is aligned with the at least one data line.

2. The liquid crystal display as recited in claim 1, wherein a voltage having an opposite polarity with respect to a voltage applied to the third electrode is applied to one of the first electrode and the second electrode, and an electric field is generated between the first electrode and the second electrode.

3. The liquid crystal display of claim 2, wherein the electric field is due to a voltage difference between the first electrode and the second electrode.

4. A liquid crystal display, comprising:

a first substrate including a first pixel electrode and a second pixel electrode formed thereon; and

a second substrate including a common electrode formed thereon, wherein the second substrate is spaced apart from the first substrate by a gap, and a voltage having an opposite polarity with respect to a voltage applied to the common electrode is applied to one of the first pixel electrode and the second pixel electrode to generate an electric field between the first pixel electrode and the second pixel electrode having a direction which coincides with a component of an electric field generated between the common electrode and the first and second pixel electrodes.

5. A liquid crystal display, comprising:

a first substrate including a first electrode and a second electrode formed thereon;

a second substrate including a third electrode formed thereon, wherein the second substrate is spaced apart from the first substrate by a gap; and

a plurality of data lines for transmitting data voltages formed on the first substrate, wherein the first and second electrodes are symmetrically disposed about at least one data line of the plurality of data lines.
