A liquid crystal display panel and the method of manufacturing the same are disclosed. Because an overlap portion of the seal pattern that encompasses in a closed form the outer edge of the image display part is minimized, excessive distribution of sealant at the overlap portion may be prevented. The liquid crystal display panel includes a first and a second substrates having at least one image display part; a main pattern on one of the first and second substrates and encompassing the outer edge of the image display part; a start pattern connected to the main pattern and formed from a point spaced apart from the image display part to a point adjacent to an outer edge of the image display part; an end pattern connected to the main pattern and formed from the point adjacent to the outer edge of the image display part to a point spaced apart from the image display part, wherein the start pattern and end pattern extend in a direction substantially parallel to a facing side of the main pattern; and liquid crystal dispensed in the image display part.

1. A liquid crystal display panel, comprising: a first and a second substrates having at least one image display part;a main pattern on one of the first and second substrates and encompassing the outer edge of the image display part;a start pattern connected to the main pattern and formed from a point spaced apart from the image display part to a point adjacent to an outer edge of the image display part;an end pattern connected to the main pattern and formed from the point adjacent to the outer edge of the image display part to a point spaced apart from the image display part, wherein the start pattern and end pattern extend in a direction substantially parallel to a facing side of the main pattern;a connection part between the start pattern and the main pattern and a connection part between the main pattern and the end pattern,wherein the connection part between the start pattern and the main pattern and the connection part between the main pattern and the end pattern cross each other at an overlap portion; andliquid crystal dispensed in the image display part. 2. The liquid crystal display panel of claim 1, wherein a size of the overlap portion is such that sealant of the overlap portion dose not come into contact with the liquid crystal before the sealant is cured. 3. The liquid crystal display panel of claim 1, wherein the start pattern and the end pattern extend as long as the length of the facing side of the main pattern. 4. The liquid crystal display panel of claim 1, wherein the start pattern and the end pattern extend in a direction substantially parallel to the main pattern while maintaining an interval (D) of about 1 mm˜5 mm from the main pattern. 5. The liquid crystal display panel of claim 4, wherein a distance (d) between the overlap portion and the start pattern or the overlap portion and the end pattern is larger than the half of the interval (D). 6. The liquid crystal display panel of claim 1, further comprising a dummy seal pattern at an outer side of the remaining sides of the main pattern where the start pattern and end pattern are not formed. 7. The liquid crystal display panel of claim 6, wherein the dummy seal pattern extends as long as the length of the facing side of the main pattern. 8. The liquid crystal display panel of claim 1, wherein the substrate is one of a first large-scale mother substrate having a plurality of thin film transistor array substrates and a second large-scale mother substrate having a plurality of color filter substrates. 9. The liquid crystal display panel of claim 1, wherein the image display part includes a first image display part and a second image display part having different size from the first image display part. 10. The liquid crystal display panel of claim 1, wherein the start pattern and the main pattern are connected in a round form and the main pattern and the end pattern are connected in a round form. 11. The liquid crystal display panel of claim 1, wherein the start pattern and the end pattern are formed to be substantially symmetric with each other. 12. The liquid crystal display panel of claim 1, wherein a distance between the start pattern and the end pattern gradually increases with the distance from the overlap portion. 13. The liquid crystal display panel of claim 1, wherein the start pattern and the end pattern are branched from the overlap portion. 14. The liquid crystal display panel of claim 1, wherein a curvature (Dr) of the connection part between the main pattern and the start pattern or the main pattern and the end pattern is larger than about 0.5 mm. 15. The liquid crystal display panel of claim 1, wherein the plurality of patterns form a single pattern connected such that the patterns surround the outer edges of the plurality of image display regions based on a single column or row. 16. A method of fabricating a liquid crystal display panel, comprising: providing a first and second substrates;providing a seal pattern with a sealant surrounding an image display part on one of the first and second substrates, wherein the seal pattern has a main pattern encompassing the outer edge of the image display part, a start pattern connected to the main pattern and an end pattern connected to the main pattern, wherein the start pattern and end pattern extend in a direction substantially parallel to a facing side of the main pattern,wherein a connection part between the start pattern and the main pattern and a connection part between the main pattern and the end pattern cross each other at an overlap portion;dispensing liquid crystal on one of the first and second substrates;attaching the first and second substrates; andcutting the attached first and second substrates along a cut line. 17. The method of claim 16, wherein the start pattern and the end pattern extend as long as the length of the facing side of the main pattern. 18. The method of claim 16, wherein the start pattern and the end pattern extend in a direction substantially parallel to the main pattern while maintaining an interval (D) of about 1 mm˜5 mm from the main pattern. 19. The method of claim 18, wherein a distance (d) between the overlap portion and the start pattern or the overlap portion and the end pattern is larger than the half of the interval (D). 20. The method of claim 16, further comprising providing a dummy seal pattern at an outer side of the remaining sides of the main pattern where the start pattern and end pattern are not formed. 21. The method of claim 20, wherein the dummy seal pattern extends as long as the length of the facing side of the main pattern. 22. The method of claim 16, wherein the image display part includes a first image display part and a second image display part having different size from the first image display part. 23. The method of claim 16, further comprising curing the sealant after the first substrate attach to the second substrate. 24. The method of claim 16, wherein the cut line is formed between the start pattern and the main pattern and between the end pattern and the main pattern, passing the overlap portion at one side of the main pattern. 25.
