Abstract

An area of a region arranged on one side of a display region in a direction in which scanning lines extend is reduced. A display apparatus has a scanning line driving circuit and a plurality of scanning lines. The scanning line driving circuit is provided in a region arranged along a side portion on the positive side in the X-axis direction in a display region of a substrate. The scanning line driving circuit includes a plurality of transfer circuits connected to the plurality of scanning lines, respectively. Among the plurality of transfer circuits, the shape of one transfer circuit is different from the shape of another transfer circuit arranged on the negative side of the one transfer circuit in the Y-axis direction.
