1. A display apparatus comprising:
a substrate including:
a first display area including a first pixel area, a second pixel area spaced apart from the first pixel area, and a transmission area; and
a second display area adjacent to the first display area;
a first pixel disposed on the first pixel area and including:
a first pixel electrode;
a first opposite electrode; and
a first intermediate layer disposed between the first pixel electrode and the first opposite electrode;
a second pixel disposed on the second pixel area and including:
a second pixel electrode;
a second opposite electrode; and
a second intermediate layer disposed between the second pixel electrode and the second opposite electrode; and
a bridge electrode electrically connecting the first opposite electrode to the second opposite electrode, wherein
a thickness of the bridge electrode varies in a direction from one of the first opposite electrode and the second opposite electrode toward the other one of the first opposite electrode and the second opposite electrode,
the first opposite electrode, the second opposite electrode, and the bridge electrode are integral with each other such that the first opposite electrode, the second opposite electrode, and the bridge electrode are together made of a single, continuous electrode,
the thickness of the bridge electrode varies such that a top surface of the bridge electrode forms an alternating concave-convex pattern while a bottom surface of the bridge electrode directly below the alternating concave-convex pattern is flat.
