Abstract
A liquid crystal display device (LCD) includes an alignment mark in a pixel region. The LCD includes upper and lower substrates; a plurality of gate lines; a plurality of data lines arranged to perpendicularly cross the gate lines on the lower substrate and defining unit pixels together with the gate lines; a switching element at each crossing of the gate lines and the data lines; first and second alignment marks disposed on respective sides of at least one of the gate lines and the data lines; a pixel electrode at each unit pixel; a black matrix on a region of the upper substrate corresponding to a boundary region of the unit pixels; and a liquid crystal layer between the upper and lower substrates. One side of the first alignment mark and one side of the black matrix lie on one straight line, and one side of the second alignment mark and the other side of the black matrix lie on one straight line.
