Abstract: A display device including 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
