Abstract: A fingerprint sensor for a display device including: a substrate having first and second surfaces; a light transmission layer including a first layer disposed on the first surface of the substrate and having first openings in at least one first conductive layer, and a second layer disposed on the first surface of the substrate and having second openings in at least one second conductive layer; a light emitting element layer disposed on the first layer and the second layer and having at least one light emitting element; and a sensor layer disposed on the second surface of the substrate and having light sensors. At least a portion of the first openings and at least a portion of the second openings at least partially overlap and have different sizes.

Abstract: A display device including a substrate; a display element layer on the substrate, the display element layer including light emitting devices; a circuit element layer between the substrate and the display element layer, the circuit element layer including signal lines and light transmitting areas which are located between the signal lines in a plan view and allow light to be transmitted therethrough; a first light blocking layer between the substrate and the circuit element layer, the first light blocking layer including first openings; and a second light blocking layer on the first light blocking layer, the second light blocking layer including second openings. The second light blocking layer includes second sub-light blocking layers disposed to be spaced apart from each other, the second sub-light blocking layers each having the second openings. The first openings of the first light blocking layer overlaps with an area between the second sub-light blocking layers.
