Abstract: A display apparatus includes a substrate, a thin-film transistor, a display element, a pad, a contact layer, and a pad-protecting layer. The substrate includes a display area and a peripheral area outside the display area. Each of the thin-film transistor and the display element is arranged in the display area. The pad is arranged in the peripheral area. The contact layer is electrically connected to the pad. The pad-protecting layer is on the contact layer and exposes a portion of the contact layer to the outside. The pad includes a first pad layer and a second pad layer. The first pad layer is connected to a connection wiring through a first contact hole. The second pad layer is spaced apart from the first pad layer and is connected to the first pad layer through a second contact hole.

Abstract: A thin film transistor (TFT) circuit device comprises a substrate comprising a major surface; a gate line formed over the substrate and extending in a first direction when viewed in a viewing direction perpendicular to the major surface; an insulating layer formed over the gate line; an electrically conductive line formed over the insulating layer and extending in a second direction when viewed in the viewing direction, the second direction being different from the first direction, the electrically conductive line comprising a source line or a data line; and a semiconductor piece formed over the substrate. The semiconductor piece comprises a portion which is located between the substrate and the gate line and overlaps the gate line and the electrically conductive line at an intersection of the gate line and the electrically conductive line when viewed in the viewing direction.
