Abstract
An organic light-emitting apparatus has a structure capable of reducing defects during the formation of an insulation layer (e.g., a pixel defining layer). The organic light emitting apparatus includes a substrate having a display area and a peripheral area surrounding the display area; a step forming layer on the peripheral area of the substrate; an insulation layer on the substrate across the display area and the peripheral area, wherein the top surface of a portion of the insulation layer corresponding to the step forming layer by covering the step forming layer is higher than the top surface of the remaining portion of the insulation layer; and a first conductive layer on the insulation layer, an end portion of the first conductive layer being close to the portion of the insulation layer corresponding to the step forming layer.
