Abstract
To provide a structure suitable for a common connection portion provided in a display panel. A common connection portion provided in an outer region of a pixel portion has a stacked structure of an insulating layer formed using the same layer as a gate insulating layer, an oxide semiconductor layer formed using the same layer as a second oxide semiconductor layer, and a conductive layer (also referred to as a common potential line) formed using the same layer as the conductive layer, in which the conductive layer (also referred to as the common potential line) is connected to a common electrode through an opening in an interlayer insulating layer provided over the first oxide semiconductor layer and an electrode opposite to a pixel electrode is electrically connected to the common electrode through conductive particles.
