Patent ID: 8189167

Claim:
A method of manufacturing a liquid crystal display (LCD) device comprising: preparing a first substrate and a second substrate; forming a sealant on one of the first and second substrates; applying liquid crystal on one of the first and second substrates; and attaching the first and second substrates; curing the sealant by irradiating UV light through a mask, wherein the mask is supported by a mask holder, wherein the mask holder includes: a lower part having a frame and a mask supporting member supporting a mask under the mask, wherein the mask supporting member directly contacts with a lower surface of the mask in the frame and has a plurality of first connecting holes formed in the mask supporting member; and an upper part having a pair of first straight bars and a plurality of second connecting holes, formed in the pair of the first straight bars, to be aligned with the first connecting holes; and a plurality of connecting members coupled with the plurality of first and second connecting holes, so that the first straight bars are coupled with the mask supporting member; wherein the frame of the lower part has four side walls, wherein the pair of first straight bars and the mask are taken within the four side walls of the frame and fixed into the frame and mask supporting member by the four side walls and the connecting members coupled with the first and second connecting holes, wherein the pair of first straight bars are separated and parallel with each other, wherein the mask supporting member has a pair of second straight bars that are separated and parallel with each other to correspond to the pair of first straight bars, respectively, wherein the pair of first straight bars and the pair of second straight bars fix a first side portion and second side portion of the mask, parallel with the first side portion, in the mask, wherein the first and second side walls of the frame have a long-edge, directly connecting first and second side surfaces of the mask, wherein a long-edge of the frame is parallel to a long-edge of the mask, and wherein the third and fourth side walls of the frame have a short-edge, separated from third and fourth side-surfaces of the mask, wherein a short-edge of the frame is parallel to a short-edge of the mask.
