Abstract
An organic light-emitting device including a first substrate with an array of organic light-emitting pixels formed thereon, and a second substrate is disclosed. A transparent moisture absorption layer is disposed between the first and second substrates. The transparent moisture absorption layer efficiently absorbs moisture and/or oxygen, and thus the lifetime characteristics of the organic light-emitting device are improved. The transparent moisture absorption layer has a transmittance of about 85% or higher with respect to visible light. The layer has a thickness of about 10 to about 60,000 nm and a refractive index of about 1.45 to about 1.65 in an inert and/air atmosphere. The layer is formed on the second substrate by using chemical vapor deposition or physical vapor deposition.
