Abstract: A dielectric layer (170) faces a surface of alight transmissive electrode (120) opposite to a surface facing an organic functional layer (110). Then, a light transmissive substrate (140) faces a surface of the dielectric layer (170) opposite to a surface facing the light transmissive electrode (120). At least apart of an optical angle change unit (150) is positioned in the dielectric layer (170) in a thickness direction of the light transmissive substrate (140). Light incident on the dielectric layer (170), for example, is reflected by a side surface of the optical angle change unit (150), and thus an incident angle with respect to a first surface (141) of the light transmissive substrate (140) decreases.

Abstract: A light emitting element includes a resonator structure which has a first reflecting member, a second reflecting member, and a light emission layer placed between the first reflecting member and the second reflecting member, and part of light resonated between the first reflecting member and the second reflecting member is transmitted through the first reflecting member or the second reflecting member in the resonator structure. A wavelength at which a resonator output spectrum from the resonator structure has a maximum value is located between a wavelength at which an inner light emission spectrum of the light emission layer has a maximum value and a wavelength at which relative luminous efficiency has a maximum value.
