Patent ID: 7880855

Claim:
A liquid crystal display device comprising: a first substrate, and a second substrate disposed opposing each other; gate lines and data lines on the first substrate disposed perpendicular to each other to define pixel regions; a black matrix layer on the second substrate disposed opposite to regions on the first substrate excluding the pixel regions; a color filter layer on the second substrate; an overcoat layer on an entire surface of the second substrate including the black matrix layer and the color filter layer; a first alignment film on the overcoat layer, the first alignment film having a first alignment film groove in the first alignment film corresponding to a predetermined portion of the black matrix layer; a first spacer in the first alignment film groove, wherein the first spacer includes a ball spacer; a seal pattern on a non-display region between the first or the second substrate; and a liquid crystal layer between the first substrate and the second substrate, wherein a width of the first alignment film groove is greater than a diameter of the first spacer.
