[PROBLEMS] To provide a technique capable of suppressing luminance variations in a light emitting element having a resonator structure and a display apparatus even when a film thickness deviates from a design value to increase or decrease a resonator optical path length, by way of example. [SOLVING MEANS] A light emitting 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, part of light resonated between the first reflecting member and the second reflecting member being transmitted through the first reflecting member or the second reflecting member in the resonator structure, and a band absorption filter transmitting the part of the light transmitted through the first reflecting member or the second reflecting member, wherein a wavelength at which the transmission of the band absorption filter has a minimum value is located between a wavelength at which a resonator output spectrum from the resonator structure has a maximum value and a wavelength at which relative luminous efficiency has a maximum value.
