Light emitting elements and display devices with increased light extraction efficiency and front luminance are disclosed. In one example, a light emitting element includes a light emitting unit, an intermediate layer covering the light emitting unit, an optical path control unit disposed on a part of the intermediate layer and having positive optical power, and a covering layer covering an outer region of the intermediate layer surrounding a part of the intermediate layer on which the optical path control unit is formed.

Light emitting element and display device with relationship between refractive indices of lens and covering layer

A light-emitting element () includes: a light-emitting part () including a light-emitting region; a first optical path control unit () which has positive optical power and to which light emitted from the light-emitting region enters; a second optical path control unit () which has positive optical power and to which light exited from the first optical path control unit () enters; and a bonding member () interposed between the first optical path control unit () and the second optical path control unit (), in which an optical axis (LN) of the first optical path control unit () is displaced from an optical axis (LN) of the second optical path control unit ().
