1. A display apparatus comprising:
a first display area comprising a plurality of pixel areas;
a second display area comprising a plurality of pixel areas and a plurality of transmission areas and located adjacent to the first display area; and
a peripheral area located outside a display area comprising the first display area and the second display area,
wherein the plurality of pixel areas each comprises sub-pixels each comprising a pixel circuit and an organic light-emitting device electrically connected to the pixel circuit,
wherein the transmission areas and the pixel areas are alternately disposed in the second display area,
the pixel circuit comprises a thin-film transistor and an inorganic insulating layer on the thin-film transistor, the thin-film transistor comprising a semiconductor layer and a gate electrode,
the inorganic insulating layer extends in the transmission areas, and
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.
