The present invention provides a liquid crystal display device having an improved aperture ratio. The liquid crystal display device of the present invention comprises: a pair of substrates positioned to face each other; and a liquid crystal layer interposed between the substrates, wherein the liquid crystal layer contains a liquid crystal molecule having positive dielectric anisotropy, the liquid crystal molecule is aligned in a direction vertical to surfaces of the substrates when no voltage is applied, one of the substrates comprises a first electrode and a second electrode, the electrodes respectively including comb-tooth portions that are alternately engaged at a certain interval, the first electrode comprises an extension in a layer separated by an insulating film from a layer in which an engagement between the comb-tooth portions of the first electrode and of the second electrode is formed, and the extension of the first electrode is positioned more distant from the liquid crystal layer than the comb-tooth portion of the second electrode is, and is positioned along the comb-tooth portion of the second electrode in an overlapping manner.
