Abstract: A display device includes a display substrate, a main circuit board, and first and second connection circuit boards. The display substrate includes a base layer, an insulating layer on the base layer, a first signal line on the base layer, a second signal line on the base layer, a first pad exposed from the insulating layer and connected to the first signal line, and a second pad connected to a side surface of the second signal line and disposed on a side surface and a bottom surface of the base layer. The first connection circuit board electrically connects the first pad and the main circuit board, and the second connection circuit board electrically connects the second pad and the main circuit board.
