A display device includes a display panel, a metal plate disposed on a bottom surface of the display panel and configured to support the display panel, a filling member disposed on the bottom surface of the display panel, the filling member being disposed on the same level as the metal plate relative to the bottom surface of the display panel, and a material of the metal plate being different from a material of the filling member, a fingerprint sensor disposed on a bottom surface of the filling member, and a member-sensor bonding member disposed between the fingerprint sensor and the filling member to bond the fingerprint sensor to the filling member. A hardness of the filling member is greater than a hardness of the member-sensor bonding member.
