Abstract

A liquid crystal display and a fabricating method thereof are disclosed in the present invention. The liquid crystal display having a display area displaying a picture and a non-display area outside the display area, wherein the non-display area includes an alignment layer on at least one of upper and lower substrates and formed from an end portion of the display area, and a sealant between the upper substrate and the lower substrate, wherein the sealant at least partially overlaps the alignment layer in a vertical direction.

Claims (18)

1. A liquid crystal display having a display area displaying a picture and a non-display area outside the display area, wherein the non-display area comprises:

an alignment layer on at least one of upper and lower substrates and formed from an end portion of the display area; and

a sealant between the upper substrate and the lower substrate, wherein the sealant partially overlaps the alignment layer in a vertical direction,

wherein a width of an overlapping area between a first side of the sealant inside the display area and an end portion of the alignment layer is about 0.3 millimeters (mm).

2. The liquid crystal display device according to claim 1 , wherein the sealant overlaps the alignment layer between 0 to about 61% of a width of the sealant measured across the sealant between a first side of the sealant inside of the display area and a second side of the sealant outside of the display area.

3. The liquid crystal display device according to claim 1 , wherein the non-display area comprises a sealant area where the sealant is positioned between the upper and lower substrates, and an outermost area defined between an end portion of the sealant area and an end portion of one of the upper and lower substrates.

4. The liquid crystal display device according to claim 3 , wherein a width of the outermost area measured between an end portion of the sealant area and an end portion of one of the upper and lower substrates is about 0.3 millimeters (mm).

5. The liquid crystal display device according to claim 1 , wherein a width of the alignment layer from an end portion of the alignment layer to the display area is about 0.9 millimeters (mm).

6. The liquid crystal display device according to claim 1 , wherein a width of the sealant measured across the sealant between a first side of the sealant inside of the display area and a second side of the sealant outside of the display area is about 1.1 millimeters (mm).

7. A fabricating method of a liquid crystal display device having a display area displaying a picture and a non-display area outside the display area, comprising:

forming an alignment layer on at least one of an upper substrate and a lower substrate from an end portion of the display area; and

forming a sealant between the upper substrate and the lower substrate such that the sealant partially overlaps the alignment layer in a vertical direction,

wherein a width of an overlapping area between a first side of the sealant inside the display area and an end portion of the alignment layer is about 0.3 millimeters (mm).

8. The fabricating method according to claim 7 , wherein the sealant overlaps the alignment layer between 0 to about 61% of a width of the sealant measured across the sealant between a first side of the sealant inside of the display area and a second side of the sealant outside of the display area.

9. The fabricating method according to claim 7 , wherein the non-display area comprises a sealant area where the sealant is positioned between the upper and lower substrates, and an outermost area defined between an end portion of the sealant area and an end portion of one of the upper and lower substrates.

10. The fabricating method according to claim 9 , wherein a width of the outermost area measured between an end portion of the sealant area and an end portion of one of the upper and lower substrates is about 0.3 millimeters (mm).

11. The fabricating method according to claim 7 , wherein a width of the alignment layer from an end portion of the alignment layer to the display area is about 0.9 millimeters (mm).

12. The fabricating method according to claim 7 , wherein a width of the sealant measured across the sealant between the first side of the sealant inside of the display area and a second side of the sealant outside of the display area is about 1.1 millimeters (mm).
