A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage.
