Liquid crystal display device

A liquid crystal display device comprising:

• a lower substrate including a display unit and a non-display unit;
• an upper substrate opposing the lower substrate;
• a liquid crystal layer interposed between the lower substrate and the upper substrate;
• a gate line and a data line disposed in the display unit of the lower substrate;
• a light shielding layer defining a pixel region of the lower substrate;
• a pixel electrode disposed in the pixel region of the lower substrate;
• a pixel transistor disposed in the display unit of the lower substrate and connected to the gate line, the data line, and the pixel electrode;
• a driving transistor disposed in the non-display unit of the lower substrate;
• a first protection layer disposed on the pixel transistor and the driving transistor;
• a shielding layer disposed on the first protection layer, the shielding layer overlapping at least one of the pixel transistor and the driving transistor and in an electrically floating state;
• a second protection layer disposed on the shielding layer;
• and
• a common electrode interposed between the first protection layer and the second protection layer to overlap the pixel electrode,
• wherein any electric signal applied to the shielding layer is absent, and
• wherein the common electrode completely surrounds the shielding layer in a plan view.
