Abstract:
1. An organic light-emitting device comprising: a first substrate comprising glass; an array of organic light-emitting pixels formed on the first substrate; a second substrate comprising glass, the second substrate opposing the first substrate and comprising an interior surface facing the first substrate; and a substantially transparent vapor deposited desiccant layer interposed between the first substrate and the second substrate, said layer consisting of metal oxide particles of one or more alkali metals or alkaline earth metals, said oxide particles having a particle size from 1 nm to 90 nm, wherein at least part of the layer has a transmittance of 95% or higher with respect to visible light and a refractive index of 1.475 to 1.594, wherein the desiccant layer has a thickness of about 200 nm to about 2,000 nm, wherein the desiccant layer is formed on the array, and wherein the metal oxide comprises one or more selected from a group consisting of sodium oxide (Na
