Liquid crystal display device

An LCD device, comprising:

• a substrate;
• a gate line, a sustain line, a data line and first through third thin film transistors (TFTs), all of which are disposed on the substrate;
• an insulating layer disposed on the data line, the gate line and the first through third TFTs;
• a first sub-pixel electrode disposed on the insulating layer, connected to a drain electrode of the first TFT via a first contact hole formed in the insulating layer, and connected to a drain electrode of the third TFT via a first sustain contact hole formed in the insulating layer;
• and
• a second sub-pixel electrode disposed on the insulating layer and connected to a drain electrode of the second TFT via a second contact hole formed in the insulating layer,
• wherein:
• gate electrodes of the first through third TFTs are connected to the gate line,
• source electrodes of the first and second TFTs are connected to the data line,
• a source electrode of the third TFT is connected to the sustain line,
• the first sub-pixel electrode includes a first stem electrode which extends in a first direction and a second direction that is perpendicular to the first direction, first branch electrodes which extend from the first stem electrode, and a first extension electrode which is disposed to overlap the first contact hole and is connected to the first branch electrodes,
• the first extension electrode includes a first slit, and
• wherein the first extension electrode includes a portion extending in one direction, the portion including the first slit and overlapping the contact hole.
