What is claimed is: 1. A method of fabricating a liquid crystal display device, comprising: forming a UV-hardening sealant on a first substrate; dropping a liquid crystal on a second substrate; attaching the first and second substrates; aligning at least one mask with the attached substrates so as to expose only an area having the sealant formed thereon; and hardening the UV-hardening sealant by applying UV-rays through the mask to the attached substrates, wherein the sealant includes one of monomer and oligomer, each having both ends coupled to an acrylic group. 2. The method of claim 1, wherein the aligning at least one mask includes forming a plurality of alignment marks on the mask and attached substrates for an alignment, and optimizing the alignment using an image device. 3. The method of claim 1, wherein the mask is formed on one of the first and second sides of the attached substrates. 4. The method of claim 3, wherein the UV-rays are irradiated only within an area of the attached substrates. 5. The method of claim 1, wherein the mask is formed on both first and second sides of the attached substrates. 6. The method of claim 5, wherein the UV-rays are irradiated on both inside and outside areas of the attached substrates so that a portion of the irradiated UV-rays is reflected to the attached substrates. 7. The method of claim 1, further comprising heating the UV-hardening sealant after hardening the UV-hardening sealant. 8. The method of claim 1, further comprising forming a column spacer on the first substrate. 9. The method of claim 1, further comprising aligning the mask with the attached substrates by using an image device. 10. A method of fabricating a liquid crystal display device, comprising: forming a UV-hardening sealant on a first substrate; dropping a liquid crystal in a second substrate; attaching the first and second substrates; aligning at least one mask with the attached substrate so as to expose only an area having the sealant formed thereon; and hardening the UV-hardening sealant by applying UV-rays through the mask to the attached substrates, wherein the sealant includes one of monomer and oligomer, each having one end coupled to an acrylic group and the other end coupled to an epoxy group. 11. The method of claim 10, wherein the aligning at least one mask includes forming a plurality of alignment marks on the mask and attached substrates for an alignment, and optimizing the alignment using an image device. 12. The method of claim 10, wherein the mask is formed on one of the first and second sides of the attached substrates. 13. The method of claim 12, wherein the UV-rays are irradiated only within an area of the attached substrates. 14. The method of claim 10, wherein the mask is formed on both first and second sides of the attached substrates. 15. The method of claim 14, wherein the UV-rays are irradiated on both inside and outside areas of the attached substrates so that a portion of the irradiated UV-rays is reflected to the attached substrates. 16. The method of claim 10, further comprising heating the UV-hardening sealant after hardening the UV-hardening sealant. 17. The method of claim 10, further comprising forming a column spacer on the first substrate. 18. The method of claim 10, further comprising aligning the mask with the attached substrates by using an image device. 19. A method of fabricating a liquid crystal display device, comprising: forming a UV-hardening sealant on a first substrate; dropping a liquid crystal on a second substrate; attaching the first and second substrates to each other; placing a mask on both first and second sides of the attached substrates so as to expose only an area having the sealant formed thereon; and irradiating UV-rays to the attached substrates covered with the masks. 20. The method of claim 19, wherein the sealant includes one of monomer and oligomer, each having both ends coupled to an acrylic groups. 21. The method of claim 19, wherein the sealant includes one of monomer and oligomer, each having one end coupled to an acrylic group and the other end coupled to an epoxy group. 22. The method of claim 19, further comprising heating the UV-hardening sealant after irradiating the UV-rays. 23. The method of claim 19, wherein the UV-rays are irradiated on both inside and outside areas of the attached substrates so that a portion of the irradiated UV-rays is reflected to the attached substrates. 24. The method of claim 19, further comprising forming a column spacer on the first substrate.
