A light-emitting diode (LED) and a manufacturing method thereof are disclosed. The LED includes: a substrate, a light-tight reflective layer, an inner epitaxial layer, an outer epitaxial layer, a non-conducting layer, an ohmic metallic body, a first electrode, and a second electrode. The inner epitaxial layer and the outer epitaxial layer are separated from each other by a separation space. In a view made from a top side of the LED, the separation space forms a closed path and surrounds the light exit hole. The separation space provides an effect of blocking an electrical current and a light emission area in the inner epitaxial layer. By redirecting light emitting from a lateral side of the inner epitaxial layer toward a top side of the LED, the LED shows a low side light ratio.
