Display device

A display device comprising:

• a first substrate including a display area and a non-display area disposed outside the display area;
• a first semiconductor disposed in the display area of the first substrate;
• a second semiconductor disposed in the non-display area of the first substrate;
• a first data conductor overlapping the first semiconductor;
• a second data conductor overlapping the second semiconductor;
• a first shielding part overlapping the first semiconductor and disposed on the first data conductor;
• a second shielding part overlapping the second semiconductor and disposed on the second data conductor;
• and
• an insulating layer disposed on the first shielding part and the second shielding part,
• wherein a second thickness of the second shielding part is larger than a first thickness of the first shielding part, and
• a fourth thickness of a second part of the insulating layer corresponding to the second shielding part is smaller than a third thickness of a first part of the insulating layer corresponding to the first shielding part.
