Abstract: A display device is disclosed that includes a substrate, a conductive layer, and a pixel defining layer. The substrate includes a first display area including pixels, a second display area including the pixels, and a transmissive area formed between the pixels of the second display area. The conductive layer is disposed in the second display area outside of the transmissive area. The pixel defining layer overlaps the conductive layer and is disposed such that an end of the pixel defining layer adjacent to the transmissive area is substantially aligned with an end of the conductive layer adjacent to the transmissive area.

Abstract: An electronic device includes a display panel with a first area including a transmissive area, an element area, and connection areas extending from the element area, and a second area. The display panel includes a first light emitting unit in the element area and including first, second, and third light emitting elements, and a first copy light emitting unit in the connection areas, including copy light emitting elements, and operating in synchronization with the first light emitting unit. The connection areas include a first connection area adjacent to the first light emitting element, a second connection area adjacent to the second light emitting element, and third and fourth connection areas adjacent to the third light emitting element. An emission color of the first light emitting element is different from an emission color of a first copy light emitting element of the copy light emitting elements in the first connection area.
