A display device includes: a first substrate; a second substrate; first signal lines on the first substrate; second signal lines on the second substrate; first lateral wires on a lateral side of a first edge of the first substrate, and connected to end portions of the first signal lines; and second lateral wires on a lateral side of a second edge of the second substrate, and connected to end portions of the second signal lines. The first and second lateral wires are located in at least one first region and at least one second region, the at least one first region and the at least one second region being spaced from each other on the lateral sides of the first substrate and the second substrate. The at least one first region includes the first lateral wires, and the at least one second region includes the second lateral wires.
