An LCD is provided to check the aligning defect by the unit pixel and prevent the leakage of light due to error of coupling between upper and lower substrates, by forming alignment marks in an active area of the LCD. A plurality of gate lines are arranged in a row direction on a lower substrate(100). A plurality of data lines(103) cross the gate lines to define a plurality of unit pixels. A plurality of switching elements are respectively formed at crossing regions of the gate and data lines. A plurality of pixel electrodes(105) are formed in respective unit pixels. A black matrix(211) is formed on an upper substrate(200) correspondingly to a boundary region between neighboring unit pixels. A plurality of first and second alignment marks(120a,120b) are respectively disposed at left and right sides of the data line above the lower substrate. A liquid crystal layer is formed between the upper and lower substrates. One side of the first alignment mark is aligned with one side of the black matrix, and one side of the second alignment mark is aligned with the other side of the black matrix.
