ABSTRACT:
A light emitting device includes a plurality of types of light emitting elements including at least a red light emitting element that outputs red light, a green light emitting element that outputs green light, and a blue light emitting element that outputs blue light. Each of the plurality of types of the light emitting elements includes a first electrode, a second electrode that is disposed on a side for outputting light and has semi-transmissive reflectivity or transparency, a function layer that is formed between the first electrode and the second electrode and includes at least a light emitting layer, a reflective layer that additionally serves as the first electrode or is formed separately from the first electrode in a position for facing the function layer through the first electrode and reflects light generated in the light emitting layer to the second electrode side, and a color filter that is disposed in a position for facing the reflective layer through the function layer and absorbs light having wavelengths in a wavelength range other than a wavelength range of the output light. In addition, at least one type of the light emitting element of the plurality of types of the light emitting elements further includes a semi-reflective layer that is disposed between the reflective layer and the function layer and a transparent layer that is disposed between the reflective layer and the semi-reflective layer.
