Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate;
• a first gate line disposed on the first substrate;
• a first common voltage line being substantially parallel to the first gate line, the first common voltage line including a plurality of expanded portions;
• a first data line and a second data line crossing the first gate line and being substantially parallel to each other;
• a first thin film transistor connected to the first gate line and the first data line and having a first channel area;
• a second thin film transistor connected to the first gate line and the second data line and having a second channel area;
• a first pixel electrode connected to the first thin film transistor in a first pixel;
• a second pixel electrode connected to the second thin film transistor in a second pixel;
• 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 defining contact holes in the insulating layer,
• wherein one of the expanded portions of the first common voltage line which is in the second pixel is overlapped by a first contact hole among the contact holes in the insulating layer, and
• wherein an expanded portion of the first common voltage line which is in the first pixel is not overlapped by any contact hole among the contact holes in the insulating layer.
