Abstract
Discussed herein is an organic light-emitting display (OLED) device that may include an organic light-emitting element layer disposed on a substrate; and an encapsulation layer covering the organic light-emitting element layer to block moisture and/or oxygen from permeating, wherein the encapsulation layer includes a barrier film having at least one transmittance adjusting layer that adjusts a ratio at which light emitted from the organic light-emitting element layer exits the OLED device, whereby the use of a polarizer is avoided.
