Abstract: The present invention relates to a micro LED structure and a method of manufacturing the same. More particularly, the present invention relates to a micro LED structure and a method of manufacturing the same, the micro LED structure including: a micro LED; a circuit board driving the micro LED; and an anisotropic conductive anodic oxide film provided between the micro LED and the circuit board to electrically connect the circuit board and the micro LED. According to the present invention, without applying an external force (thermocompression bonding) to the anisotropic conductive anodic oxide film, it is possible to electrically connect the circuit board and the micro LED. In addition, it is possible to obtain characteristics such as uniform conductivity in a vertical direction and heat dissipation.
