Abstract:
1. A liquid crystal display device comprising: an upper substrate and a lower substrate, which face each other; a liquid crystal layer formed between the upper substrate and the lower substrate; and a column spacer formed between the upper substrate and the lower substrate, wherein the column spacer includes a main column spacer that is in contact with both the upper substrate and the lower substrate and a sub column spacer that is in contact with the upper substrate but is not in contact with the lower substrate, a width of the main column spacer in a horizontal direction parallel, from a front view, to a direction the upper substrate extends is the same as a width of the sub column spacer and a height of the main column spacer in a direction perpendicular, from the front view, to the direction the upper substrate extends is different from a height of the sub column spacer, wherein the main column spacer overlaps, from a top view, a line-shape portion of a black matrix layer but does not overlap a rectangular shape portion, wherein the black matrix layer overlapping the main column spacer includes the line-shape portion and the rectangular shape portion that protrudes on both sides from the line-shape portion, the sub column spacer overlaps, from the top view, a line-shape portion without a rectangular shape portion of the black matrix layer protruding from the line-shape portion, the line-shape portion having the rectangular shape portion of the black matrix layer protruding on both sides from the line-shape portion overlaps at least one gate line, the line-shape portion having the rectangular shape portion of the black matrix layer protruding on both sides from the line-shape portion is separated from the line-shape portion without the rectangular shape portion of the black matrix layer protruding from the line-shape portion, and a width of the line-shape portion having the rectangular shape portion of the black matrix layer protruding on both sides from the line-shape portion is greater, from the front view and the top view, than a width of the line-shape portion without a rectangular shape portion of the black matrix layer protruding from the line-shape portion, and wherein the lower substrate includes gate and data lines thereon to define a pixel region, the gate lines including the at least one gate line, the gate and data lines crossing each other.
