Abstract: A display device with increased light transmittance to a functional module includes a substrate, a light blocking layer, an insulating layer, emission elements, and a polarization member. The substrate includes a first display region including a first pixel region and a transmission region, and a second display region surrounding at least a portion of the first display region and including a second pixel region. The light blocking layer is disposed in both display regions on the substrate and includes a first opening overlapping the transmission region. The insulating layer covers the light blocking layer on the substrate. The emission elements are disposed in the first and second pixel regions on the insulating layer. The polarization member is disposed on the emission elements and includes a second opening overlapping die first opening. An area of the second opening is greater than or equal to an area of the first opening.

Abstract: An electronic device includes a display device and an electronic device. The display device includes a base layer, a circuit element layer, a display element layer, an encapsulation layer, a cover inorganic layer, a cover organic layer, an anti-reflection layer, and a filling part configured to overlap the first area. The electronic device is disposed below the base layer and configured to overlap the first area. A module hole is defined in the display module through which the circuit element layer, the display element layer, the encapsulation layer, the cover inorganic layer, and the cover organic layer overlapping the first area passes through to expose the base layer, and the filling part is disposed inside the module hole and is in contact with a portion of the base layer exposed by the module hole.
