A semiconductor package includes a first semiconductor chip having a first surface and a second surface. First connection pads are adjacent to the first surface. A second semiconductor chip has a lower surface facing the first surface of the first semiconductor chip and includes second connection pads, Connection bumps contact the first connection pads and the second connection pads between the first semiconductor chip and the second semiconductor chip. An adhesive layer is interposed between the first semiconductor chip and the second semiconductor chip to at least partially surround the connection bumps. The adhesive layer includes a protruding portion protruding from a side surface of the second semiconductor chip. A barrier structure covers a portion of the first connection pads, partially overlapping the second semiconductor chip on the first surface, and contacting the protruding portion of the adhesive layer.

A semiconductor element bonding substrate according to the present invention includes an insulating plate, and a metal pattern bonded to a main surface of the insulating plate. A main surface of the metal pattern on an opposite side of the insulating plate includes a bonding region to which a semiconductor element is bonded by a solder. The metal pattern includes at least one concave part located in the main surface. The at least one concave part is located closer to an edge of the bonding region in relation to a center part of the bonding region in the bonding region.

A display panel includes a first substrate, a second substrate, a plurality of light-emitting components, a bonding layer and a driving component. The first substrate includes a planar portion and a bending portion. The second substrate is disposed on the first substrate. The light-emitting components are disposed on the second substrate. The bonding layer is disposed between the planar portion of the first substrate and the second substrate. The driving component is disposed on a first surface of the bending portion of the first substrate and electrically connected to the light-emitting components. The first surface of the bending portion extends from a surface of the planar portion adjacent to the second substrate, and a projection of the bending portion in a vertical direction falls within the second substrate. A tiled display device including multiple display panels and a manufacturing method of the display panel are also provided.
