Abstract: An organic light-emitting display includes a substrate including a first pixel region, a second pixel region, and a division region disposed between the first pixel region and the second pixel region, an insulating layer disposed on the substrate and including a recess disposed in the division region, the insulating layer including a first inner side wall defining a first portion of the recess and a second inner side wall extending from the first inner side wall, defining a second portion of the recess, and having a curved shape, a plurality of pixel electrodes disposed on the insulating layer, a spacer disposed on a side wall of each of the pixel electrodes and the first inner side wall, and a first organic emission layer disposed on the spacer, wherein the spacer includes a material having an etch selectivity different than an etch selectivity of the insulating layer.
