PROBLEM TO BE SOLVED: To provide an OLED device having improved sealing, and a reduced chip size, especially provide an OLED device formed on a thin or flexible substrate to prevent mechanical damage on an active device layer. SOLUTION: The device includes a barrier layer arranged on the substrate, a sealing dam surrounding a cell region and containing material selected from polybenzoxazoles, polyglutarimid, and benzocyclobutene, a cap supported by the sealing dam, spacer particles in a region of the device for supporting the cap, a sealing region adjacent to an external surface of the sealing dam, and adhesive as a tightly closing material arranged in the sealing region. The adhesive air-tightly seals the device, and the sealing dam reduces a sealing width of the device. The spacer particles are randomly distributed in the cell region. COPYRIGHT: (C)2010,JPO&INPIT
