Abstract: An electronic apparatus comprises a display panel and a component on a lower surface of the display panel. The display panel includes a first display area with first light-emitting diodes, a second display area with display element groups that include second light-emitting diodes, transmission areas in the second display area, a pixel-defining layer surrounding an emission area of each of the first and second light-emitting diodes, an upper insulating layer, and a thin-film encapsulation layer. The component overlaps the second display area in a plan view. In a boundary portion of the first and second display areas, the pixel-defining layer and the upper insulating layer form a staircase-shaped step, and the upper insulating layer includes at least one protrusion portion protruding towards the second display area from an edge of the upper insulating layer.
