Abstract

A light emitting element includes a first electrode, a second electrode facing the first electrode, and a plurality of light emitting structures stacked between the first electrode and the second electrode, each of the plurality of light emitting structures including a hole transport region, a light emitting layer, and an electron transport region. At least one of the light emitting structures is a green light emitting structure which emits green light, and the light emitting layer of the green light emitting structure includes a first sub-light emitting layer including a low refractive material having a refractive index value less than or equal to about 1.7 at 460 nm, and a second sub-light emitting layer not including the low refractive material, and disposed on the first sub-light emitting layer, so that the light emitting element may exhibit high light emission efficiency.
