Abstract

A light-emitting device, a method of manufacturing the same and an electronic apparatus. The light-emitting device includes a silicon-based base substrate; at least one organic light-emitting diode device at the silicon-based base substrate; a first encapsulation layer, at a side of the at least one organic light-emitting diode device away from the silicon-based base substrate and including one or more sublayers; a color filter layer, at a side of the first encapsulation layer away from the at least one organic light-emitting diode device; and a second encapsulation layer, at a side of the color filter layer away from the first encapsulation layer and including one or more sublayers. A refractive index of at least one sublayer in the first encapsulation layer is greater than a refractive index of at least one sublayer in the second encapsulation layer.
