Liquid crystal device and the array substrate thereof

A liquid crystal device and an array substrate are disclosed. At least one data line and at least one pixel cell are arranged on the array substrate. A gap is formed between the data line and the pixel cell, and an electrode is arranged on the gap to cover the gap. In this way, the light leakage is avoided.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to liquid crystal display technology, and more particularly to a liquid crystal device (LCD) and the array substrate thereof.

2. Discussion of the Related Art

As shown inFIG. 1, one conventional Thin Film Transistor Liquid Crystal Display (TFT-LCD)10includes an up substrate11, a down substrate12, a data line13and a pixel cell14arranged above the down substrate12. There is a gap between the data line13and the pixel cell14. When the up substrate11and the down substrate12are dislocated, the gap between the data line13and the pixel cell14becomes larger. When the LCD10displays a white image, a voltage difference is generated in the gap as the data line13carries electricity. As such, the liquid crystal located close to the gap and the up substrate11change their alignment, which results in light leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

FIG. 2is a schematic view of the LCD in accordance with one embodiment. The LCD20includes an array substrate21, an up substrate22, and an electrode23.

The array substrate21includes a data line211and a pixel cell212arranged thereon. There is a gap213between the data line211and the pixel cell212. The up substrate22is arranged above the array substrate21. The up substrate22includes a black matrix221and a common electrode222. The black matrix221is arranged above the data line211. That is, the black matrix221is right above the data line211. The common electrode222covers the up substrate22and the black matrix221. Preferably, the common electrode222is Indium Tin Oxides (ITO). The electrode23is arranged above the gap213. That is, the electrode23is for covering the gap213to avoid light leakage.

In the embodiment, the LCD20further includes a liquid crystal layer24arranged between the array substrate21and the up substrate22. Light beams cannot emit out from the liquid crystal layer24if the liquid crystal within the liquid crystal layer24have not been twisted. That is, the light beams emit out from the liquid crystal layer24when the liquid crystal layer24is twisted.

In one embodiment, the electrode23electrically connects to the common electrode. As there is no voltage difference between the electrode23and the common electrode222, the liquid crystals within the liquid crystal layer24between the electrode23and the common electrode222are not twisted such that the light beams cannot emit out from the liquid crystal layer24so as to avoid light leakage.

Preferably, the electrode23is ITO electrode. When manufacturing the ITO mask of the LCD20, the ITO is manufactured above the gap213to form the electrode23. Thus, the electrode23may be formed without additional manufacturing process. In addition, the width of the data line211has not to be widen, which decreases the aperture rate of the LCD20.

In the embodiment, the electrode23is arranged on the gap213between the data line211and the pixel cell212. The electrode23covers the gap213to avoid the light leakage. In addition, the electrode23may be formed without additional manufacturing process.

In addition, the claimed invention also disclose one array substrate for the LCD20. The array substrate may be the array substrate21as described above.

In view of the above, the electrode23is arranged on the gap213between the data line211and the pixel cell212. The electrode23covers the gap213to avoid the light leakage. In addition, the electrode23may be formed without additional manufacturing process.
