Abstract: A display apparatus includes a first sub-pixel electrode, a conductive bank layer including a first opening overlapping the first sub-pixel electrode in a plan view, an insulating layer between a peripheral portion of the first sub-pixel electrode and the conductive bank layer, a first intermediate layer disposed on the first sub-pixel electrode in the first opening of the conductive bank layer, and a first counter electrode disposed on the first intermediate layer in the first opening of the conductive bank layer. The conductive bank layer comprises a first conductive layer, a second conductive layer on the first conductive layer, and a third conductive layer on the second conductive layer. The first counter electrode has a width greater than a width of the first intermediate layer. The first counter electrode is in direct contact with the conductive bank layer.
