Abstract
According to one embodiment, a display device includes a first substrate, a second substrate including a common electrode, and a display function layer which is partly switched between a transparent state and a scattering state. The first substrate includes a first scanning line, a first signal line, an insulating layer, a first switching element, and a first pixel electrode. The first signal line includes a first coupling portion and a first line portion. The first scanning line intersects the first coupling portion and is provided in a same layer as the first line portion. The insulating layer is interposed between the first coupling portion and the first scanning line.
