The liquid crystal injected into the picture displaying area.

Claims (20)

1. A liquid crystal display device, comprising:

two plates, one plate of the two plates having a protrusion thereon for defining a picture displaying area, the protrusion being formed of indium-tin-oxide (ITO);

a sealant formed along edges of the other plate of the two plates, a position of the sealant being outside of the protrusion; and

a liquid crystal evenly dispersed into the picture displaying area such that the protrusion completely contains the liquid crystal in the picture displaying area.

2. The liquid crystal display device according to claim 1 , wherein the liquid crystal is dispersed using a liquid crystal dispensing method.

3. A method of fabricating a liquid crystal display device, comprising the steps of:

providing two plates, one plate of the two plates having a protrusion thereon for defining a picture display area, the protrusion being formed of indium-tin-oxide (ITO);

forming the sealant on the other one of the two plates, a position of the sealant being outside of the protrusion;

evenly dispensing liquid crystal onto the picture display area using a liquid crystal dispensing method; and

joining the two plates.

4. The method according to claim 3 , wherein the liquid crystal remains completely contained in the picture display area during the step of joining the upper plate with the lower plate.

5. A liquid crystal display device, comprising:

two plates, one plate of the two plates having a protrusion thereon for defining a picture displaying area, the protrusion being formed of metal;

a sealant formed along edges of the other plate of the two plates, a position of the sealant being outside of the protrusion; and

a liquid crystal evenly dispersed into the picture displaying area such that the protrusion completely contains the liquid crystal in the picture displaying area.

6. A method of fabricating a liquid crystal display device, comprising the steps of:

providing two plates, one plate of the two plates having a protrusion thereon for defining a picture display area, the protrusion being formed of metal;

forming the sealant on the other one of the two plates, a position of the sealant being outside of the protrusion;

evenly dispensing liquid crystal onto the picture display area using a liquid crystal dispensing method; and

joining the two plates.
