Abstract
The present invention relates to a method for manufacturing a light-emitting device and the light-emitting device manufactured using same, which can reduce manufacturing costs, form nanopatterns in a large area, and increase light extraction efficiency. One embodiment of the present invention discloses the method for manufacturing a light-emitting device, comprising: a light-emitting structure preparation step for preparing a light-emitting structure including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer, which are formed sequentially; a light extraction layer formation step for forming the upper part of the second conductive semiconductor layer as a light extraction layer having an uneven pattern; a dipping step for dipping the light-emitting structure having the light extraction layer in a solution in which nanomaterials are dispersed; and an adsorption step for adsorbing the nanomaterials to the light extraction layer.
