Disclosed are an LED and an LED module. The LED includes: a first conductivity type semiconductor layer; a mesa disposed over the first conductivity type semiconductor layer and including an active layer and a second conductivity type semiconductor layer; a first ohmic-contact structure in contact with the first conductivity type semiconductor layer; a second ohmic-contact structure in contact with the second conductivity type semiconductor layer; a lower insulating layer at least partially covering the mesa and the first conductivity type semiconductor layer and disposed to form a first opening part at least partially exposing the first ohmic-contact structure and a second opening part at least partially exposing the second ohmic-contact structure; and a current distributing layer connected to the first ohmic-contact structure at least partially exposed by the first opening part and disposed to form a third opening part at least partially exposing the second opening part.
