ABSTRACT:
An organic electroluminescent display includes a substrate (1), and, in order from the substrate, a hole injection electrode, at least one organic layer, an electron injecting electrode, and a sealing plate, and wherein the substrate further includes thereon an element-isolating structure (7,8) for isolating planar structures of the organic layer and the electron injection electrode from each other during film formation, the element isolating structure being a solid structure containing a base part formed on the substrate side and an overhang part larger in width than the base part, and provided on a portion where the organic layer is isolated from the electron injecting electrode as well as other portions, so that the element isolating structure can function as a spacer for the sealing plate, and at least one type of filter layer (14a-14c) is interleaved between the element-isolating structure serving as the spacer and the substrate.
