Light emitting device for improving the color purity of emitted light and electronic apparatus

A light emitting device comprising:

• a light emitting element which includes a first electrode layer, a second electrode layer, and a light emitting function layer disposed between the first electrode and the second electrode;
• a reflection layer which reflects light emitted from the light emitting function layer toward the light emitting function layer;
• and
• a translucent transflective layer which is disposed opposite the reflection layer with the light emitting function layer interposed therebetween to reflect some of the light emitted from the light emitting function layer toward the light emitting function layer and to transmit the remainder of the light, wherein the translucent transflective layer is centered between a high refractive index layer having a refractive index n3 and being disposed on a side of the reflection layer and an inert gas having a refractive index n4 (where n4<n3) and being disposed opposite the high refractive index layer, the inert gas directly contacts the translucent transflective layer.
