Abstract

A source plate for a liquid crystal display, a fabrication method thereof, and a liquid crystal display produced by the method. The source plate includes a first substrate, including a plurality of pixel regions having first electrodes respectively disposed therein; a second substrate, including a plurality of pixel regions having second electrodes disposed therein, positioned to be in opposition to the first substrate; a sealing agent surrounding each pixel region, disposed between the first substrate and the second substrate; a liquid crystal inlet disposed at an opening in each of the sealing agents; an assistance sealing agent disposed between adjacent sealing agents; and a liquid crystal disposed in the pixel regions. The method includes forming the assistance sealing agents to prevent injected liquid crystal from entering a space between the pixel regions.

Claims (24)

1. A source plate for liquid crystal displays, comprising:

a first substrate;

a second substrate disposed opposite to the first substrate;

a plurality pixel regions, each comprising first electrodes disposed in the first substrate and second electrodes disposed in the second substrate;

a plurality of sealing agents disposed between the first substrate and the second substrate, each sealing agent surrounding one of the pixel regions;

liquid crystal inlets disposed at an opening of each of the sealing agents;

a plurality of assistance sealing agents disposed between adjacent sealing agents, to prevent a liquid crystal from entering spaces between the sealing agents; and

a dispersion plate disposed in each of the liquid crystal inlets,

wherein the sealing agents, the assistance sealing agents, and the dispersion plates, are formed of the same material.

2. The source plate of claim 1 , wherein the assistance sealing agents are disposed adjacent to the liquid crystal inlets.

3. The source plate of claim 1 , wherein the assistance sealing agents, the sealing agents, and the dispersion plates comprise an epoxy.

4. The source plate of claim 1 , wherein the second electrodes are common electrodes.

5. The source plate of claim 1 , wherein the assistance sealing agents are strip-shaped.

6. The source plate of claim 5 , wherein one or more of the assistance sealing agents connect adjacent sealing agents.

7. The source plate of claim 5 , wherein one or more of the assistance sealing agents extend from a sealing agent to an edge of the source plate.

8. The source plate of claim 5 , wherein one or more of the assistance sealing agents connect adjacent sealing agents, and one or more of the assistance sealing agents extend from a sealing agent to an edge of the source plate.

9. A liquid crystal display device comprising a source plate,

the source plate comprising: a first substrate; a second substrate disposed opposite to the first substrate;

a plurality pixel regions, each comprising first electrodes disposed in the first substrate and second electrodes disposed in the second substrate;

a plurality of sealing agents disposed between the first substrate and the second substrate, each sealing agent surrounding one of the pixel regions;

liquid crystal inlets disposed at an opening of each of the sealing agents; and

a plurality of assistance sealing agents disposed between adjacent sealing agents, to prevent a liquid crystal from entering spaces between the sealing agents,

a dispersion plate disposed in each of the liquid crystal inlets,

wherein the sealing agents, the assistance sealing agents, and the dispersion plates, are formed of the same material.
