1. An organic light-emitting display device, comprising:
a transistor;
a pixel electrode electrically connected to the transistor;
a pixel-defining layer on the pixel electrode, the pixel-defining layer comprising:
an opening overlapping a portion of the pixel electrode; and
a bank portion enclosing the opening and covering edges of the pixel electrode;
a multi-layered structure overlapping the portion of the pixel electrode and comprising a functional layer and an emission layer;
an opposite electrode over the multi-layered structure, edges of the opposite electrode being located over the bank portion of the pixel-defining layer; and
a protective layer over the opposite electrode and extending beyond edges of the opposite electrode, edges of the protective layer being located over the bank portion of the pixel-defining layer.
