A light emitting diode (LED) structure includes a substrate, an LED element, a reverse current protection element, a third conductor, and a fourth conductor. The LED element includes a first N-type semiconductor layer, a first lighting layer, a first P-type semiconductor layer, a first transparent conductive layer, a first electrode, and a second electrode. The reverse current protection element is located on the substrate and surrounds the LED element. The reverse current protection element includes a stack layer, a first conductor, and a second conductor. The stack layer is formed on the substrate by sequentially stacking a second N-type semiconductor layer, a second lighting layer, and a second P-type semiconductor layer. The third conductor is electrically connected to the first conductor and the second electrode. The fourth conductor is electrically connected to the second conductor and the first electrode.
