Abstract: The present invention provides an AC plasma display device using metal nanostructures, including: a front panel and a rear panel which are disposed in parallel to each other and at least one of which is provided with electrodes for gas discharge; an electrode layer, a front dielectric layer and a protective film which are sequentially formed on a side of the front panel which faces the rear panel; a phosphor layer which is formed on the rear panel and which is excited and simultaneously radiated by gas discharge occurring in the electrodes; and metal nanostructures included in the protective film and the phosphor layer, and provides a method of manufacturing the same. The AC plasma display device can improve a secondary electron emission coefficient and photoluminescent intensity using surface plasmon excitation because it is provided with a protective film including metal nanostructures.

Abstract: Disclosed herein is an organic light emitting diode device, including: an organic EL element layer; an electrode layer supplying power to the organic EL element layer; and a metal nanocluster layer which is formed by covering a plurality of metal clusters with media and which is located between the organic EL element layer and the electrode layer to induce a luminescence enhancement effect. The organic light emitting diode device is advantageous in that carriers can be easily injected, so that light output efficacy is improved, thereby enhancing fluorescent emission output.
