a metal plate and a filling member which are disposed on a lower surface of the display panel, are disposed on a same layer, and include different materials; and
a fingerprint sensor which is disposed on a lower surface of the filling member and is overlapped by the filling member in a thickness direction, wherein the fingerprint sensor is disposed entirely outside of the metal plate,
wherein the metal plate includes a plurality of outlines extending in different directions in a plan view defined perpendicular to the thickness direction, one outline of the metal plate includes a plurality of sides extending along a first direction and a discontinuous part disposed between the sides, an open part recessed from the discontinuous part in a second direction intersecting the first direction is formed in the metal plate, and the filling member is located in the open part in the plan view, and
wherein the filling member only partially fills the open part in the plan view, a side surface of the filling member is located inward from a first line connecting the sides via the discontinuous part, and a space is defined between the side surface of the filling member and the first line to allow for an expansion of the filling member into the space in at least the second direction.
