    Abstract: A light-emitting device and an electronic apparatus including the same are provided. The light-emitting device includes a first electrode, a second electrode facing the first electrode, an interlayer between the first electrode and the second electrode and including an emission layer, and a capping layer. The emission layer includes a first emitter, the first emitter emits a first light having a first emission spectrum, the capping layer is in a path on which the first light travels, an emission peak wavelength of the first light is about 520 nm to about 550 nm. The first emitter includes iridium, the capping layer includes an amine-free compound, and the value of ratio of CIEy to reflective index (RCR value) of the first light extracted to the outside through the capping layer is 38 or less, and the RCR value is calculated according to CIEy/R(cap)×100.

    Abstract: Provided is a color filter having improved light efficiency and color reproducibility. The color filter includes: a substrate having a plurality of pixel areas and a light blocking area surrounding the plurality of pixel areas; a light blocking layer on the light blocking area; a first color conversion layer on a first pixel area among the plurality of pixel areas and configured to convert incident light into light of a first color; a first color filter layer between the substrate and the first color conversion layer and configured to selectively transmit the light of the first color emitted from the first color conversion layer; and a light reflection layer between the first color conversion layer and the first color filter layer and including a reflective material.
