Liquid crystal display device

A display device comprising:

• a first substrate;
• a gate line disposed on the first substrate and extending substantially in a first direction;
• a gate electrode protruding from the gate line in a second direction crossing the first direction;
• a common voltage line separated from the gate line;
• a data line crossing the gate line and including a source electrode, the data line having two opposing edges each extending substantially in the second direction;
• a thin film transistor including the gate electrode, the source electrode, a drain electrode opposing the source electrode, and a channel area between the source electrode and the drain electrode;
• a pixel electrode connected to the drain electrode of the thin film transistor;
• a common electrode disposed on the first substrate and overlapping the pixel electrode;
• and
• an insulating layer between the common voltage line and the common electrode, the insulating layer defining a contact hole,
• wherein
• the common electrode is electrically connected to the common voltage line through the contact hole, and
• the common electrode defines:
• a plurality of slits overlapping the pixel electrode,
• an enclosed opening overlapping the gate electrode, a portion of the gate line which is adjacent to the gate electrode, an entire width of the source electrode along the first direction, the channel area, and the two opposing edges of the data line in a plan view, and
• an outer boundary of the enclosed opening of the common electrode having a first edge crossing the data line, and a second edge crossing the data line,
• wherein
• the outer boundary of the enclosed opening surrounds the gate electrode, and
• the first edge and the second edge oppose each other in the second direction in the plan view with an entirety of the gate electrode and entire width of the gate line along the second direction between the first edge and the second edge.
