Abstract
A vertical GaN-based LED includes an n-type bonding pad; an n-electrode formed under the n-type bonding pad; a light-emitting structure formed by sequentially laminating an n-type GaN layer, an active layer, and a p-type GaN layer under the n-electrode; a p-electrode formed under the light-emitting structure; and a support layer formed under the p-electrode. The light-emitting structure has or or more trenches which are spaced at a predetermined distance with the n-electrode from the outermost side of the light-emitting structure and in which the active layer of the light-emitting structure is removed.
