Abstract
The manufacturing yield of a display device is improved. The resistance of a display device to ESD is increased. The display device includes a substrate, a display portion, a connection terminal, a first wiring, and a second wiring. The first wiring is electrically connected to the connection terminal and includes a portion positioned between the connection terminal and the display portion. The second wiring is electrically connected to the connection terminal, is positioned between the connection terminal and an end portion of the substrate, and includes a portion in which a side surface is exposed at an end portion of the substrate. The display portion includes a transistor. The transistor includes a semiconductor layer, a gate insulating layer, and a gate electrode. The semiconductor layer and the second wiring include a metal oxide.
