Display panel including light shielding line, display device having the same and method of manufacturing the same

A display device comprising:

• a display panel which displays an image with light, the display panel comprising:
• a substrate comprising:
• a first light blocking area lengthwise extending in a first direction,
• a second light blocking area lengthwise extending in a second direction intersecting the first direction, and
• a pixel area at which the image is displayed, the pixel area defined by the first light blocking area and the second light blocking area which intersect each other;
• a first shielding line and a second shielding line spaced apart from each other on the substrate at the first light blocking area;
• a data line between the first shielding line and the second shielding line at the first light blocking area, the data line spaced apart from the first shielding line and the second shielding line;
• a gate line disposed on the substrate at the second light blocking area, the gate line intersecting the data line;
• and
• a thin film transistor connected to the data line and the gate line,
• wherein
• the first shielding line comprises a first protrusion protruding toward the second shielding line, and the second shielding line comprises a second protrusion protruding toward the first shielding line,
• the first protrusion or the second protrusion is overlapped by the thin film transistor, and
• the first shielding line and the second shielding line are disposed in a same layer of the display panel as the data line among layers disposed on the substrate of the display panel.
