Abstract
Disclosed is a full-color LED display device and a manufacturing method thereof. The full-color LED display device includes 1) a plurality of first electrodes formed on a substrate, 2) at least five subminiature blue LED elements attached to each unit pixel site formed on the first electrode, 3) an insulation layer formed on the substrate and the blue LED element, 4) a plurality of second electrodes formed on the insulation layer, and 5) a green color conversion layer and a red color conversion layer formed on the second electrode corresponding to partial unit pixel sites selected from the unit pixel sites. The manufacturing method of a full-color LED display device includes 1) forming a plurality of first electrodes on a substrate, 2) attaching at least five subminiature blue LED elements to each unit pixel site formed on the first electrode, 3) forming an insulation layer on the substrate, 4) forming a plurality of second electrodes on the insulation layer, and 5) successively patterning a green color conversion layer and a red color conversion layer on the second electrode corresponding to partial unit pixel sites selected from the unit pixel sites.
