Abstract
Display device and fabrication method are provided. The display device includes a first substrate and a flexible circuit board. The first substrate includes a step region, first alignment marks, and a base substrate. The step region includes a bonding region and the bonding region includes a plurality of first pads arranged in at least one row along a first direction. The flexible circuit board is bonded in the bonding region and includes second alignment marks. Orthographic projections of the first alignment marks on a plane of the base substrate do not overlap an orthographic projection of the flexible circuit board on the plane of the base substrate, and do not overlap orthographic projections of the second alignment marks on the plane of the base substrate.
