Claim:
1. A core-shell structure semiconductor light emitting device, comprising: a base layer formed of a first conductivity-type semiconductor material; an insulating layer on the base layer and having a plurality of openings; a plurality of light emitting core-shell structures each in a separate opening of the plurality of openings, the light emitting core-shell structures being spaced apart from each other, each light emitting core-shell structure including a core formed of the first conductivity-type semiconductor material, and a separate shell including an active layer and a second conductivity-type semiconductor layer sequentially disposed on surfaces of the core; and a contact electrode spaced apart from the insulating layer and on a portion of the second conductivity-type semiconductor layer, the contact electrode being on at least a tip portion of each respective light emitting core-shell structure; and an insulating protective layer filling a continuous whole space between the plurality of light emitting core-shell structures and contacting lower regions of the plurality of light emitting core-shell structures, wherein the tip portion of each respective light emitting core-shell structure has crystal planes different from those on side surfaces of the respective light emitting core-shell structure.
