Display device and manufacturing method of the same

A display device comprising:

• a base substrate comprising a first light blocking area extending in a first direction, a second light blocking area extending in a second direction intersecting the first direction and a light transmitting area defined by the first light blocking area and the second light blocking area;
• a gate line disposed on the base substrate at the first light blocking area;
• a data line disposed on the base substrate at the second light blocking area;
• a thin film transistor connected to the gate line and the data line;
• a protective layer disposed on the thin film transistor;
• a black matrix disposed on the protective layer at at least one of the first light blocking area and the second light blocking area;
• and
• a pixel electrode disposed on the black matrix and connected to the thin film transistor through a contact hole defined in the protective layer and the black matrix.
