Abstract: A liquid crystal display (“LCD”) device includes: a first substrate having a first area that allows an image to be transmitted therethrough and a second area that blocks an image; a second substrate opposite to the first substrate; a liquid crystal layer between the first substrate and the second substrate; and a polarizing layer on the second substrate. The polarizing layer may include first polarizing patterns and second polarizing patterns, wherein, in a planar view, the first polarizing patterns overlap with the first area and the second polarizing patterns overlap with the second area.
