The invention provides a light-emitting device and an electronic device and a consumer product including the light-emitting device. The light emitting device includes a first electrode, a second electrode facing the first electrode, an intermediate layer between the first electrode and the second electrode and including an emission layer, and a capping layer. The emission layer includes a first emitter that emits first light having a first emission spectrum, and the capping layer has an emission peak wavelength of about 520 nm to about 550 nm on a path along which the first light travels. The first emitter contains iridium, the capping layer contains a compound that does not contain an amine, and a ratio value of CIEy to refractive index (RCR value) of the first light led out to the outside through the capping layer is 38 or less, and the RCR value CIEy/R (capp) x 100 is calculated according to the following formula. 本申请提供了发光装置以及包括发光装置的电子设备和消费品。所述发光装置包括第一电极、面对所述第一电极的第二电极、在所述第一电极与所述第二电极之间并且包括发射层的中间层、以及覆盖层。所述发射
