An organic light-emitting device includes a first pixel electrode disposed on a substrate, a first bank covering an edge of the first pixel electrode, the first bank having a first opening exposing a portion of the first pixel electrode, a second pixel electrode covering the exposed portion of the first pixel electrode through the first opening, the second pixel electrode covering at least a portion of the first bank, an organic light-emitting layer covering the second pixel electrode, and an opposite electrode covering the organic light-emitting layer.
