A display device includes: a substrate including first and second light-blocking areas, and a pixel area; a light-blocking pattern at least partially at the first light-blocking area; a data line at the second light-blocking area; a first insulating layer on the light-blocking pattern and the data line; a semiconductor layer on the first insulating layer and overlapping the light-blocking pattern on a plane; a second insulating layer on the semiconductor layer; a color filter on the second insulating layer at least partially at the pixel area; a third insulating layer on the second insulating layer and the color filter; a gate line on the third insulating layer at the first light-blocking area; a pixel electrode at least partially at the pixel area; and a bridge electrode at least partially at the first light-blocking area. The second and third insulating layers directly contact one another over the semiconductor layer.
