The liquid crystal display device includes a first insulation substrate, a gate line which is disposed on the first insulation substrate and extends substantially in a first direction, first and second data lines which are insulated from the gate line, extend substantially in a second direction and intersect the gate line, a pixel electrode which includes first and second sub-pixel electrodes which are each provided with different data voltages via the first and second data lines, respectively, and which are separated from each other by a gap, the second sub-pixel electrode at least partially overlapping the first and second data lines, a second insulation substrate which faces the first insulation substrate, a black matrix which is disposed on the second insulation substrate and includes an irregular shape and extends substantially along the first and second data lines and a liquid crystal layer which is interposed between the first and second insulation substrates.
