Abstract
There are provided an organic light emitting display and a method of manufacturing the organic light emitting display. The organic light emitting display includes a lower substrate including a plurality of subpixel regions, a thin film transistor formed on the lower substrate, an organic light emitting element formed on the thin film transistor, an encapsulation unit for covering the organic light emitting element, a spacer formed on the encapsulation unit, an upper substrate disposed to face the lower substrate, and a desiccant between the lower substrate and the upper substrate. Various embodiments of the invention provide an organic light emitting display that enhances a viewing angle by minimizing a cell gap and minimizing a distortion of light, minimizes penetration of water or oxygen from the outside, and realizes a high resolution display by enhancing an aperture ratio, and a method of manufacturing the organic light emitting display.
