Disclosed is a technology of preferentially forming an ohmic contact layer and a conductor layer before separating a nanorod light emitting diode (LED) from a substrate, thereby being capable of omitting a heat treatment process performed at high temperature after aligning the nanorod LED, and, accordingly, preventing electrical short while maximizing the quantum efficiency of the nanorod LED and increasing a selection range of a material constituting a light emitting diode (LED) display. More particularly, the nanorod LED includes a first semiconductor layer; a multi-quantum well structure layer; a second semiconductor layer; and a conductor layer formed on at least one semiconductor layer of the first semiconductor layer and the second semiconductor layer, wherein a length and shape of the conductor layer are controlled such that the multi-quantum well structure layer is disposed between two electrodes of the electrode pattern on which the conductor layer is to be aligned.

The present invention relates to a wireless charging system including a boost converter and a transmission coil structure at a transmission side. The wireless charging system includes a boost converterconfigured to boost a first DC voltage input to an input terminal to a second DC voltage, a DC/AC inverterconfigured to receive the boosted second DC voltage from the boost converter to convert the received second DC voltage to AC power, and a transmission coil structurewhich is electrically connected to the DC/AC inverter to generate a temporally variable magnetic field for wireless supplying from the AC power. The first DC voltage and the second DC voltage of the boost convertermay be maintained to predetermined fixed values. The transmission coil structureis formed by winding a wire on a magnetic sheet many times in a spiral shape and the winding coil has a circular shape having predetermined inner radius and outer radius, a pitch, and the turn number. Further, the transmission coil structure may include a plurality of coil structures and the plurality of coil structures may have a laminated structure by connecting wires having different cross-sectional areas in series.
