Abstract: A display apparatus includes a first display area including a plurality of pixel areas, and a second display area including a plurality of pixel areas and a plurality of transmission areas and arranged adjacent to the first display area. The plurality of pixel areas each includes sub-pixels each including a pixel circuit and an organic light-emitting device electrically connected to the pixel circuit. The pixel circuit includes a thin-film transistor and an inorganic insulating layer on the thin-film transistor, and the thin-film transistor includes a semiconductor layer and a gate electrode. The organic insulated layer extends in the transmission areas. The second display area defines a dummy contact hole which passes through the inorganic insulating layer in at least one of the pixel areas and the transmission areas.
