1. A liquid crystal display device comprising:

  • a first substrate;

    a second substrate facing the first substrate;

    a liquid crystal layer interposed between the first substrate and the second substrate;

    a first gate line and a second gate line disposed on the first substrate and being substantially parallel to each other;

    a first common voltage line and a second common voltage line being substantially parallel to the first gate line;

    a first data line and a second data line crossing the first gate line and the second gate line and being substantially parallel to each other;

    a first pixel electrode disposed in a first pixel;

    a second pixel electrode disposed in a second pixel adjacent to the first pixel in a column direction parallel to the first and second data lines;

    a common electrode disposed on the first substrate and overlapping the first pixel electrode and the second pixel electrode; and

    an insulating layer between the first common voltage line and the common electrode and between the second common voltage line and the common electrode,whereinarranged in order along the column direction are the first gate line, the first common voltage line, the second pixel electrode, the second gate line and the second common voltage line, the first gate line and the first common voltage line being spaced apart from each other along the column direction to define a space therebetween,the first common voltage line includes a length portion substantially parallel to the first gate line and the first common voltage line, and an expanded portion which protrudes directly from the length portion and at which the first common voltage line overlaps the common electrode,a portion of the second pixel electrode overlaps the length portion of the first common voltage line and includes an edge of the second pixel electrode disposed in the space between the first gate line and the first common voltage line, the edge being substantially parallel to the first gate line and the first common voltage line, andthe portion of the second pixel electrode which overlaps the length portion of the first common voltage line and includes the edge is spaced apart from the expanded portion which protrudes directly from the length portion, along a direction substantially parallel to the first gate line and the first common voltage line.
