    Abstract: A display device includes a light sensing array layer (LSAL), a substrate, a selective light transmission layer (SLTL), a pixel circuit layer (PCL), a display element layer (DEL), and pixels. The LSAL includes an optical sensor to sense incident light. The substrate is on the LSAL and includes a display area (DA) including pixel areas (PAs), and a non-DA adjacent to the DA. The SLTL is disposed on the substrate and includes through-holes to form a path of light onto the optical sensor, and a light-blocking conductive pattern (LBCP) between the through-holes. The PCL is disposed on the SLTL and includes a conductive layer and an insulation layer. The DEL is disposed on the PCL and emits light. Each pixel includes a pixel circuit disposed on the PCL, and a light emitting element on the DEL in a corresponding pixel area. The LBCP is electrically connected to the conductive layer.

    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.
