Display device

A display device comprising:

• a substrate;
• a data line disposed on the substrate;
• a first pattern disposed on the substrate and spaced apart from the data line;
• a light-blocking layer disposed between the substrate and the first pattern;
• an inorganic insulating layer disposed between the light-blocking layer and the first pattern;
• a first insulating layer at least partially disposed on the data line and the first pattern;
• an active layer disposed on the first insulating layer and at least partially overlapping with the first pattern;
• a first gate insulating layer disposed on the active layer;
• and
• a first electrode disposed on the first gate insulating layer and overlapping with the active layer,
• wherein the first electrode does not overlap with the data line in a direction parallel to an upper surface of the first insulating layer,
• wherein the first electrode is in contact with the active layer via a first contact hole passing through the first gate insulating layer so that at least a part of the active layer is exposed via the first contact hole,
• wherein the first electrode, the active layer, the first pattern, and the first contact hole are overlapping with each other in a direction perpendicular to an upper surface of the substrate,
• wherein the first pattern is insulated from the active layer, the first electrode, and the data line, and
• wherein the light-blocking layer is overlapped by the first pattern and the active layer in the direction perpendicular to the upper surface of the substrate.
