Abstract
A display device includes: a first substrate; a second substrate on the first substrate and exposing a first edge portion of the first substrate, the second substrate protruding beyond a second edge portion of the first substrate; a connection line on the first edge portion of the first substrate, the connection line having a first end portion protruding beyond a first side of the second substrate and a second end portion covered by the second substrate; and a thin-film transistor layer on the second substrate and connected to the connection line. The thin-film transistor layer includes signal lines extending from the first side to a second side of the second substrate. The signal lines extend into contact openings in the thin-film transistor layer and are exposed at a lower part of the second substrate on the second side of the second substrate.
