摘要： A display device including a first substrate including a display area, and a non-display area, a second substrate on the first substrate, and a sealing member in a sealing area of the non-display area. The first substrate includes a first base portion, a first conductive layer including a first signal line and a lower light blocking layer, on the first base portion, a buffer layer on the first conductive layer, a semiconductor layer overlapping the lower light blocking layer, on the buffer layer, a gate insulating layer on the semiconductor layer, and a second conductive layer including second and third signal lines electrically connected to the first signal line, and a gate electrode overlapping the semiconductor layer, on the gate insulating layer. In plan view, the first signal line is between the second signal line and the third signal line. The first signal line overlaps the sealing member.
