1. An electronic apparatus comprising:
a display panel comprising:
a first display area;
first light-emitting diodes disposed in the first display area;
a second display area;
display element groups comprising second light-emitting diodes, the display element groups disposed in the second display area;
transmission areas disposed in the second display area,
a pixel-defining layer disposed on a substrate and surrounding an emission area of each of the first light-emitting diodes and each of the second light-emitting diodes;
an upper insulating layer disposed above the pixel-defining layer; and
a thin-film encapsulation layer overlapping the first light-emitting diodes and the second light-emitting diodes in a plan view, the thin-film encapsulation layer comprising an inorganic encapsulation layer and an organic encapsulation layer; and
a component disposed on a lower surface of the display panel and overlapping the second display area in a plan view, wherein
the pixel-defining layer and the upper insulating layer form a staircase-shaped step in a boundary portion of the first display area and the second display area, and,
the upper insulating layer comprises at least one protrusion portion disposed in the boundary portion of the first display area and the second display area, the at least one protrusion portion protruding in a direction towards the second display area from an edge of the upper insulating layer.
