Abstract:
1. An organic light emitting diode display comprising: a display substrate; an encapsulation substrate arranged opposite to the display substrate; at least one organic light emitting diode interposed between the display and encapsulation substrates; a sealant interconnecting the display substrate and the encapsulation substrate while surrounding the at least one diode such that the sealant, the display substrate, and the encapsulation substrate form an enclosed space therein; a plurality of spacers that are formed in a central portion and in a peripheral portion of at least one of the display substrate and the encapsulation substrate and configured to maintain a predetermined gap between the display substrate and the encapsulation substrate within the enclosed space, wherein heights of the plurality of spacers correspond to a distance from the central portion of the display substrate, wherein the heights of the spacers in the central portion are less than the heights of the spacers in the peripheral portion of the display substrate; and a filler configured to fill at least some of the enclosed space, wherein the filler overlaps at least one of the spacers.
