Abstract
This invention provides a top-emitting OLED display device that includes a substrate; an array of OLED elements disposed on one side of the substrate; and a desiccant material provided in a patterned arrangement over the array of OLED elements on the same side of the substrate such that the desiccant material does not interfere with the light emitted by the OLED elements.
