    • PURPOSE: A light emitting diode and a manufacturing method thereof are provided to increase side optical extraction efficiency through an incline plane of the sidewall of the light emitting diode. CONSTITUTION: A column structure body is formed on a substrate(100). The column structure body comprises an N-type layer(102), an active layer(104), and a P-type layer(106). A passivation layer(108) is formed on the surface of the N-type layer. An electrical insulating layer(110) is charged in a section between sidewalls of the passivation layer. A first electrode(114) contacts with a sub-wavelength surface structure of a transparent conductive layer(112). A second electrode contacts with a semiconductor layer of a first type. A semiconductor of a second type is covered by the transparent conductive layer. The semiconductor layer of the first type is the N-type layer. The semiconductor of the second type is the P-type layer.
