An organic light emitting display can include a substrate, a first capacitor formed on the substrate, the first capacitor including a first capacitor lower electrode, a first capacitor upper electrode, and a gate insulating layer between the first capacitor lower upper electrodes, a first passivation layer over the first capacitor, a second capacitor on the first passivation layer, the second capacitor including a second capacitor lower electrode, a second capacitor upper electrode, and a second passivation layer interposed between the second capacitor lower upper electrodes, an organic insulating layer over the second capacitor, a pixel electrode on the organic insulating layer, an organic layer on the pixel electrode, the organic layer including at least a light emitting layer, and an opposite electrode on the organic layer, and the width of the second capacitor lower electrode is greater than that of the second capacitor upper electrode.
