Abstract
An organic light emitting diode display apparatus includes a substrate and a pixel structure disposed on the substrate. The pixel structure includes an active element, a first electrode electrically connected to the active element, a bank layer disposed on the first electrode, a light emitting layer disposed on the first electrode and an opening of the bank layer, and a second electrode disposed on the light emitting layer. The first electrode has a first region and a plurality of protrusions disposed outside the first region. The opening of the bank layer overlaps with the first region and the protrusions of the first electrode.
