Abstract: A substrate of an electronic device may include a first test region and a second test region to measure resistance at a connection portion. The first test region and the second test region each comprise a plurality of measuring pad portions, a protective layer disposed on the plurality of measuring pad portions, and a contact assistance member disposed on the protective layer. The protective layer in the first test region comprises a first contact hole exposing the plurality of measuring pad portions. The contact assistance member in the first test region contacts the measuring pad portion exposed through the first contact hole. The protective layer in the second test region comprises two second contact holes exposing one measuring pad portion, and the contact assistance member in the second test region contacts the one measuring pad portion through the two second contact holes.

Abstract: A display device includes a first substrate, a flexible printed circuit, and a film. The flexible printed circuit is disposed on a first area of the first substrate. The film is disposed on the first substrate and the flexible printed circuit. The flexible printed circuit includes a second substrate, a pad area, and a dummy pad. The pad area comprises pads disposed on the second substrate. The pads extend in a first direction and are spaced apart from one another in a second direction crossing the first direction. The dummy pad is disposed on the second substrate. The dummy pad is spaced apart from the pad area.
