Abstract
A light-emitting device includes a first electrode layer; a second electrode layer; a third electrode layer separated from the first and second electrode layers; a multi-quantum well (MQW) layer between the first electrode layer and the second and third electrode layers; a first material layer between the first electrode layer and the MQW layer and doped with a first conductive type dopant; a second material layer between the second and third electrode layers and the MQW layer and doped with a second conductive type dopant; a gate insulating layer between the third electrode layer and the second material layer; and a current blocking layer configured to at least partially block a flow of a current between the second electrode layer and the MQW layer.
