Display device

A display device, comprising:

• a substrate including a display area and a non-display area surrounding the display area;
• a light blocking pattern disposed on the substrate and including a coupling portion extending in a first direction and a plurality of protrusion portions protruding in a second direction crossing the first direction from the coupling portion;
• a semiconductor pattern disposed on the light blocking pattern and including a source area, a channel area and a drain area;
• a gate insulating layer disposed on the semiconductor pattern;
• a gate wiring including a gate line extending in the first direction on the gate insulating layer and a gate electrode overlapping the channel area;
• an interlayer insulating layer formed on the gate wiring;
• a first contact hole for exposing the source area through the interlayer insulating layer;
• a data wiring extending in the second direction on the interlayer insulating layer and electrically connected to the source area via the first contact hole;
• a first passivation layer disposed on the data wiring;
• a second contact hole, which is disposed between the neighboring protrusion portions of the light blocking pattern so as not to overlap the light blocking pattern, and exposes the drain area through the interlayer insulating layer and the first passivation layer;
• a pixel electrode disposed on the first passivation layer and electrically connected to the drain area through the second contact hole;
• a common electrode, which is disposed between the first passivation layer and the pixel electrode and to which a common voltage is applied;
• and
• a common wiring, which is disposed in a closed loop shape in the non-display area and surrounds the display area, being electrically connected to the common electrode,
• wherein the coupling portion is connected to the common wiring which provides the common voltage,
• wherein the common electrode and the common wiring are disposed on directly on a same layer, and
• wherein the common electrode includes the same material as the common wiring.
