Abstract: 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.

Abstract: The present disclosure provides a display device with fingerprint sensor in a manner capable of strengthening a display device integrating the fingerprint sensor. The display device includes a display panel including a display area, a cover panel, a fingerprint sensor, and a reinforcing member. The cover panel is disposed on a rear surface of the display panel and includes an opening. The fingerprint sensor is disposed on the rear surface of the display panel in the opening of the cover panel and includes a sensor layer. The reinforcing member is disposed on a rear surface of the fingerprint sensor. The reinforcing member includes a sidewall surrounding at least one area of the sensor layer while being in contact with the rear surface of the fingerprint sensor, and a bottom surface which extends from the sidewall and is spaced apart from the sensor layer.
